**Bambuddy 1.2.5**
**⚠ Upgrade Notes — Read Before Updating**
**About the version number.** This is the successor to **0.2.4.9** — the first digit moved from **0** to **1** (0.2.5 became 1.2.5). It is a normal next release on the same code base, not a rewrite; the jump in the leading digit is only a versioning-scheme change. The in-app Apply Update button in Settings → System → Updates works for Docker and for any native install already on the 0.2.x line.
1.2.5 folds in the whole beta cycle, so it is a large release. There are no breaking schema changes beyond auto-migrated column additions (dialect-branched for SQLite and Postgres), and every migration was run against both engines.
**Behaviour-change callouts to know about before you upgrade:**
- **Bed levelling, flow calibration, and nozzle-offset calibration are now three-way Off / Auto / On, and new prints default to Auto.** This matches Bambu Studio (Auto lets the printer skip a calibration it did recently). Your existing queued prints and saved workflow defaults are migrated automatically — anything that was "on" becomes "On (force)", anything "off" stays "Off" — so nothing changes for in-flight jobs until you opt into Auto.
- **Docker now shuts down gracefully.** Previously every docker stop / restart / image update was a SIGKILL after the full grace period — no WAL checkpoint, no MQTT disconnect, no clean teardown. That is fixed (uvicorn is now PID 1 and receives the signal). To also pick up the raised stop grace period, refresh your docker-compose.yml (it now sets stop_grace_period: 30s). systemd/launchd/Windows launchers get the equivalent timeout automatically via the installer.
- **Multi-printer farms dispatch far faster.** Uploads to different printers now run concurrently (new Settings → Workflow → Queue & Dispatch → Concurrent Uploads, default 4, up to 16 — set it to 1 for the old strictly-serial behaviour), and the scheduler re-ticks within seconds after a productive pass instead of waiting a fixed 30 s. A stuck printer is now failed after three attempts instead of retried forever.
- **PostgreSQL pool defaults raised and made configurable.** The pool is now 20 + 80 (100) by default with DB_POOL_SIZE / DB_MAX_OVERFLOW / DB_POOL_TIMEOUT / DB_POOL_RECYCLE overrides, plus a GET /api/v1/system/db-pool gauge. If you run a large farm on Postgres, review your server's max_connections headroom — see the PostgreSQL wiki page.
- **Bambu Cloud sign-in state is now honest.** A lapsed token is properly detected instead of showing "Connected" forever, and a single stray 401 no longer signs you out. If you linked your Bambu account before enabling authentication (or crossed an auth on/off transition on an older build), you may need to re-link once from the Profiles page.
- **Manual jog safety (Bambu firmware bug).** Bambu firmware does not enforce its soft endstops on G-code received over MQTT, so manual jog can overrun a travel limit. Bambuddy no longer disables the endstops globally around a jog (which previously also broke the touchscreen's limits until a power-cycle) and now shows a prominent warning on the jog panel. If your printer currently overruns even from its own touchscreen, power-cycle it once to restore the endstops an older Bambuddy build disabled.
- **P1S / P1P AMS drying is screen-only.** P1 firmware acks drying commands and discards them, so Bambuddy no longer offers Start/Stop for P1 drying — the flame button stays visible but disabled with an explanation. A cycle started at the printer still shows its live countdown.
- **REST smart-plug energy (Shelly users).** If your Energy JSON Path points at a cumulative lifetime counter (anything from a Shelly does), move it to the new Energy JSON Path (lifetime) field so Today/Yesterday/Total populate correctly.
- **Re-take your backups after upgrading.** A Postgres → SQLite backup export previously dropped NOT NULL / DEFAULT / FK / UNIQUE; that is fixed, but backups taken on an older build still carry the degraded schema.
- **Stats.** Reconciled-after-reconnect prints no longer inflate Total Print Time by hundreds of hours. Rows already inflated by the old bug are not auto-corrected (they're indistinguishable from real cancellations) — repair them by hand if needed.
Make a backup before upgrading via Settings → Backup → Create Backup. Native install with update.sh snapshots the database automatically and rolls back on failure. Docker and fully-manual paths don't.
**Docker**
docker compose pull
docker compose up -d
Refresh docker-compose.yml if you want the new stop_grace_period: 30s (recommended, so a slow teardown on a Pi isn't clipped).
**Native install — recommended path**
sudo BRANCH=main /opt/bambuddy/install/update.sh
Snapshots the database first and rolls back on failure. Also carries any custom ReadWritePaths you added (e.g. for NAS backups) forward into the new systemd unit.
**Native install — manual path**
sudo systemctl stop bambuddy
cd /opt/bambuddy
sudo -u bambuddy git fetch --prune --tags --force origin
sudo -u bambuddy git checkout main
sudo -u bambuddy git reset --hard origin/main
sudo /opt/bambuddy/venv/bin/pip install -r requirements.txt
cd frontend && sudo npm i
sudo systemctl start bambuddy
**Windows install**

---
**Highlights**
1.2.5 is a big release that lands several long-requested features on top of a large stability and farm-scale correctness pass.
**New surfaces:**
- **Slicer Pipelines** — save a printer/process/filament/bed-type bundle once and dispatch it with a click. Full production-batch semantics: multi-copy runs, printer-class targeting, three fan-out strategies (max parallel / round robin / fill one first), a runs dashboard with cancel and retry-failed, and live updates (#1425).
- **Cam Wall** — a full-page grid of live camera tiles on the Printers page, with a per-tile print-status overlay, a bookmarkable /camwall URL, and a purpose-built read-only kiosk token for a lobby TV that exposes no serial, IP, or filename (#2531).
- **HMS error actions** — the error dialog goes from read-only to actionable: Resume / Stop / Ignore / Check Assistant and the rest now send the matching command to the printer, so you no longer have to walk to the machine to clear a pause (#1743, #1830).
- **AMS Filament Backup** — read and toggle the printer's auto-switch-to-a-second-spool state right from the card, and a paused runout now names the exact physical slot the printer is waiting for (#2587).
**Farm and stability:**
- Prints on a multi-printer farm no longer start one-by-one up to an hour apart — uploads run concurrently and the scheduler re-ticks as printers free up (#2555).
- A sustained session-hygiene and pool-sizing pass stops PostgreSQL connection-pool exhaustion on large farms, where camera streams, FTP work, and 3MF parsing had been holding DB connections across slow I/O (#2572, #2573).
- Docker finally shuts down cleanly instead of being SIGKILLed on every stop, and a run of multi-plate dispatch bugs that could map the wrong filament, log the wrong plate, or split a dispatch across two printers are fixed (#2551, #2552, #2603, #2614, #2615).
**Smaller-but-useful:** batch/mass edit on the Filament tab (#1795), structured storage-location and user-tag catalogs plus recursive search and per-folder README panels in the File Manager (#1505, #1268), continue-drying-while-printing on capable hardware, a dedicated AI Failure Detection notification event (#1794), sort Printers by ETA
(#1609), admin-configurable session lifetime (#1706), a full Russian translation (#2608, 11 languages total), and much more below.
---
**New Features**
Slicer Pipelines (#1425):
- Save and reuse a preset bundle in one click from the Slice modal (PR A).
- Run a pipeline on a file (library or archive) with one click, with pre-flight eligibility and a progress toast (PR B).
- Multi-copy batches, printer-class targeting, three fan-out strategies, a runs dashboard with cancel/retry-failed, and live WebSocket updates (PR C — completes the v3 design).
Cam Wall (#2531):
- Cam Wall view on the Printers page — a responsive grid of live camera tiles with on-screen/live-budget scheduling so it stays sustainable on a Pi.
- Per-tile print/printer status overlay (Off / Compact / Full).
- Bookmarkable /camwall URL plus a purpose-built read-only kiosk token that serves only what a tile draws — no serial, IP, access code, or filename.
Printer control and status:
- HMS error actions on the dashboard — Resume / Stop / Check Assistant etc. now send the matching MQTT command (#1743, contributed by @Ichicoro).
- AMS Filament Backup status + control on the printer card, read from the print.cfg bit and toggled over MQTT.
- A paused AMS runout now names the physical slot the printer is actually waiting for, with a pulsing highlight on the AMS graphic (#2587).
- AMS drying badge shows the active cycle's filament and target temperature.
- Live print progress for Virtual Printers in Bambu Studio / OrcaSlicer while keeping the Send button enabled (#1887).
Inventory:
- Batch / mass edit on the Filament tab — bulk edit / print labels / reset usage / archive / delete across both built-in and Spoolman modes (#1795).
- Structured storage-locations catalog (shelves, drawers, dryboxes) with Spoolman parity (#1505, closing #1004, contributed by @Poltavtcev).
- By-tag spool lookup readable with a Manage-Inventory API key, for scanner-driven integrations (#1700 closing #1663, contributed by @bambuman).
- Spoolman weight tracking for no-3MF "Untitled" prints, closing a parity gap with built-in inventory (#1820).
File Manager (#1268):
- User-authored tags for cross-cutting file filtering, independent of folders.
- Recursive search inside the selected folder, and a per-folder markdown README panel (collapsible right-hand rail).
- Page-wide drag-and-drop upload (#1510), and sort the folder tree by recent activity (#1770).
Drying:
- Continue auto-drying while a print is running, on capable hardware (opt-in, temperature-capped).
Notifications:
- Dedicated "AI Failure Detection" notification event so Obico detections stop riding the multiplexed Printer Error toggle (#1794).
- Inline finish-photo embed in failure-event emails via the {finish_photo_url} template variable, plus user_print_* template disambiguation (#1792).
Accounts, API keys, and layout:
- QR code on API-key creation that encodes server URL + key together for one-scan mobile setup (#1677, contributed by @bambuman).
- Admin-configurable session lifetime (24h / 7d / 30d, default 24h) (#1706).
- Centralised sidebar layout with per-page hide toggles and an admin default order (#1673, contributed by @EdwardChamberlain).
- Per-VP G-code injection toggle for Studio Send / FTP uploads (#1516, contributed by @phieb).
Other:
- Slice as designed — keep a MakerWorld author's own embedded settings when slicing server-side, when your printer matches the design's target (#2611).
- Sort the Printers page by ETA (#1609).
- Unified print dispatch through the queue scheduler, so every print is queueable, cancellable, and attributable (#1625, by @EdwardChamberlain).
- Sticky upload-progress toast restored for scheduler-driven dispatch (#1625 follow-up).
- Sponsor surfaces now ask a print farm (5+ printers) a commercial question instead of the hobbyist donation ask.
- Russian (Русский) UI translation — 11 languages total (#2608, contributed by @pterodaktil02).
- Appliance endpoints for NTP-gate state and locale/hostname/timezone defaults.

**Fixed**
Dispatch, scheduler, and farm scale:
- Prints on a multi-printer farm started one-by-one, up to an hour apart — uploads now run concurrently (#2555).
- A printer that accepted a file but never started was retried forever — now failed after three attempts (#2555).
- Every job waited up to 30 s after a printer freed up — the scheduler now re-ticks fast after a productive pass (#2555).
- PostgreSQL connection-pool exhaustion on large farms, plus a sustained session-hygiene pass so camera streams, cover/snapshot/timelapse, the print-start and finish-photo handlers, notification snapshots, FTP helpers, and SMTP no longer hold a DB connection across slow I/O (#2572).
- Startup connected printers serially (~100 s to first response on a 93-printer farm) — now concurrent (#2572).
- Queue polling re-parsed every 3MF on each poll — now a single combined parse cached by file revision (#2573).
- Large prints uploaded twice at once and never landed — deadline now scales with file size and actually cancels a too-slow transfer, with a per-printer upload lock (#2529).
- queue_max_concurrent_uploads behaved as a per-batch cap instead of a refillable pool (#2602).
- Reassigning a queue item mid-dispatch split it across two printers (#2615), a start dispatched to an already-busy printer could cancel the running job (#2598), and an unresolved AMS mapping silently dispatched to the empty external spool (#2589).
Multi-plate and filament mapping:
- Skip Objects listed the wrong plate's objects (#2522), and single-plate object lists could crash dispatch.
- Queueing several plates of one file mapped them all through the first plate's filaments (#2551), Filament Override vanished for a multi-plate selection (#2552), and Force color match made every plate wait for every colour (#2551).
- A single plate of a multi-plate 3MF recorded the whole file's filament in statistics (#2614), and multi-plate queue prints lost the selected plate in Print History (#2603).
- A print mapped to a different filament than it was sliced for was logged under the sliced material, not the one used (#2563).
- Multi-nozzle prints no longer collapse all filaments onto one nozzle (#1825), and nozzle sizes other than 0.4 mm are fully supported in the AMS slot picker + a pre-dispatch guard (#1899).
AMS and filament:
- A2L "AMS Lite" slots showed empty and never deducted filament (unit id 16 normalisation).
- The HT-A (AMS-HT) spool vanished a few seconds after power-on (#2594).
- External spool kept its old inventory filament after a type change (#2575), and configuring a built-in/generic filament reverted a moment later (#2604).
- An AMS slot with a non-Bambu (no-RFID) spool showed "Empty" instead of "?" (#2527), and the drying "Rotate spool" toggle is no longer offered when a tray is threaded out.
Camera:
- P1/A1 camera stayed black on load until a ~20-minute self-heal — late-subscriber priming + teardown discipline (#2521, #2521 follow-ups).
- Cam Wall no longer kills shared streams when one viewer closes, and offline tiles show OFF rather than LIVE.
- P2S RTSP timeout could leave the fan-out stream permanently stalled (#2580, diagnosed by @ronaldheft, fix shape from PR #2581).
Cloud, MakerWorld, and connectivity:
- Bambu Cloud dropped to "sign-in expired" and forced constant re-logins (any-401 now narrowed to the documented token-expiry response) (#2530-related, and the #2562 follow-up).
- Enabling authentication silently disconnected Bambu Cloud — the token now migrates onto the admin (and back) across the auth transition (#2530).
- "Please login." during MakerWorld import while showing Connected — cloud status is now authoritative.
- MakerWorld import on Windows failed with a certificate error (S3 hop now verifies against certifi) (#2562).
- MakerWorld import/resolve/status failed under API-key auth even with a valid owner cloud login (#1777).
- H2C prints intermittently recorded no filament — the H2C now gets the TLS 1.2 FTP profile (#2582), and H2C prints now deduct from inventory (#2582).
Shutdown and launchers:
- Docker never shut down gracefully — every stop/restart/update was a SIGKILL (exec uvicorn as PID 1).
- systemctl restart could hang 90 s and end in SIGKILL when a camera stream was open — every launcher now bounds the graceful-shutdown wait.
Smart plugs and energy:
- Energy Summary stuck at zero for Yesterday and Total on REST smart plugs, plus the whole smart-plug subsystem was broken on Postgres (naive-vs-aware datetimes) (#2539).
- Switching off an accessory smart plug at print end knocked the printer into "Unknown" and stalled the queue — plugs now carry a "Powers the printer" flag (#2629).
Other fixes:
- Reconnect/restart inflated Stats → Total Print Time by hundreds of hours (#2592).
- Scheduled backups to a NAS failed with EROFS because of our own systemd ProtectSystem sandbox — installers now carry custom ReadWritePaths forward and the UI diagnoses the real cause (#2544).
- Postgres → SQLite backup dropped NOT NULL / DEFAULT / FK / UNIQUE (#2526).
- Every SpoolBuddy screen crashed when a text field was focused (CJS interop) (#2616).
- The streaming overlay (/overlay) was blank in OBS with login enabled — now a token-authenticated kiosk surface (#2613).
- The AMS slot popup covered the filament dialog it opened, on touch devices (#2631).
- Slicing a single plate failed on a filament slot the plate doesn't use, and a profile could be auto-picked for a printer it doesn't belong to (#2628 and follow-up).
- Pushover Emergency priority (2) was rejected by the API (#2586); progress notification ran off-screen in the iPhone PWA (#2612).
- "Remember Me" appeared broken — an authenticated visit to /login now redirects (#1889).
- Packaging floors that permitted un-runnable resolutions: FastAPI < 0.116 204-route crash, sqlalchemy floor raised to 2.0.38, ruff pinned exactly; printer FTPS/MQTT now declare a TLS 1.2 floor explicitly.
(This is a condensed list — see CHANGELOG.md for the full detail on every entry, including tests and scope.)
---
**Security**
- Bumped linkify-it and dompurify to their patched releases (both build/production-tree hygiene; neither reachable path was exposed).
- Raised the Docker image's pip floor to 26.1.2 (PYSEC-2026-196) — build tooling only.
- Bumped two frontend dev-tooling dependencies (brace-expansion, js-yaml) with denial-of-service advisories — lint/build-time only, not in the shipped app.

📰 As Featured In
"Bambuddy is the companion app that Bambu Lab should have built from day one." — Adam Conway, XDA-Developers
Two leading 3D-printing publications independently concluded that Bambuddy's feature set already exceeds Bambu's own cloud:
"The features seem to exceed those provided by Bambu Lab's own cloud." — Fabbaloo
"The list of functions seems so extensive that it even goes beyond what Bambu Lab offers in its own cloud." — 3Druck.com
🌐 NEW: Remote Printing with Proxy Mode
Print from anywhere in the world — Bambuddy's new Proxy Mode acts as a secure relay between your slicer and printer:
- 🔒 End-to-end TLS encryption — FTP, file transfer, and camera are transparently proxied with the printer's real TLS certificate
- 🛡️ Optional Tailscale integration — per-VP toggle + Docker socket mount surface the host's Tailscale IP on the VP card, so you know which
100.x.x.xto paste into the slicer when you want a virtual printer reachable over your tailnet (setup). Bambuddy's self-signed CA import is still required on the slicer side: Bambu Studio / OrcaSlicer validate printer TLS against a bundled BBL CA (not the system trust store), and their Add Printer dialog is IP-only (no hostname to match an LE cert against), so a publicly-trusted cert can't help on either dimension. Tailscale's role is the private tunnel (reachability from anywhere, no port forwarding), not cert-import elimination. - 🌍 No cloud dependency — Direct connection through your own Bambuddy server
- 🔑 Uses printer's access code — No additional credentials needed
- ⚡ Full-speed printing — Transparent TCP proxy, only MQTT is decrypted for IP rewriting
Perfect for remote print farms, traveling makers, or accessing your home printer from work.
🍰 NEW: Integrated Slicing — Slice & Print, All In One Place
No desktop slicer required. Drop an STL or 3MF into Bambuddy's File Manager, hit Slice, and the result lands as a ready-to-print .gcode.3mf in the same folder — without ever opening Bambu Studio or Orca Slicer.
- 🍰 One-click slicing — Slice from any browser. The job runs server-side in a tiny sidecar container, progress streams back as a toast, and the sliced file appears in your library when it's done.
- 📱 Slice from your phone or tablet — Bambuddy's PWA + the new server-side slicer means you can drop an STL in from mobile and queue a print without ever touching a desktop.
- 🎒 Bring your own profiles — Import a
Printer Preset Bundle(.bbscfg) exported from Bambu Studio: pick a curated printer + process + filament triplet from a dropdown in the Slice dialog, no more juggling JSON files. - 🔄 Re-slice for a different printer in one click — Open any sliced archive in Bambuddy and re-slice it for any printer, including across the single-nozzle ↔ dual-nozzle (H2D / H2D Pro) boundary that BambuStudio's CLI would normally reject. Bambuddy detects the class change and auto-arranges objects laid out for the source bed (e.g. X1C 256×256) so they land safely on the target (e.g. H2D 350×320 with its per-nozzle dead zones).
- 🍱 Slice all plates at once — Multi-plate projects (parted statues, multi-part kits) get a "Slice all N plates" toggle in the Slice dialog. One click produces a single
.gcode.3mfcontaining every plate's gcode, ready for the printer. The toast shows "Plate 2 of 5 — Generating G-code (47%)" as the loop runs. - 🔁 Same dispatch as the rest of Bambuddy — The sliced output flows into the existing queue / plate-picker / AMS-mapping path, so all the regular conveniences (multi-printer dispatch, AMS routing, scheduled prints) just work.
Optional but recommended — drop the slicer-api/ Compose stack next to your Bambuddy install and the Slice button lights up everywhere.
🧩 NEW: Slicer Pipelines — Save a Recipe, Reuse in One Click
Stop re-picking the same printer + process + filament + bed-type combination every slice. Save a Slicer Pipeline once from the Slice dialog, then apply the whole bundle to any file with a single click — from File Manager, Archives, or MakerWorld imports.
- 🧩 One-click reuse — A pipeline captures the entire Slice modal selection (printer + process + per-AMS-slot filaments + bed type) and surfaces as Run with pipeline → <name> on every sliceable row.
- 🎯 Specific printer or printer class — Pin a pipeline to one printer, or to a class (e.g. any X1C) and let the queue scheduler pick the first available match. Identical-fleet farms get a single recipe instead of one-per-printer.
- 🪢 Multi-copy fanout — Slice once, dispatch up to N copies. With class targeting the copies fan out across the matching printers in parallel — Spread (fastest wall-clock), Single printer (minimise colour-change overhead), or First N (one to each).
- 📊 Runs dashboard — A new Pipelines tab on the Print Queue page lists every run with colour-coded status badges (queued / slicing / dispatching / in-progress / completed / partial-failure / failed / cancelled), per-copy detail on expand, filter dropdowns (Pipeline / Status / Target), and a Retry failed button that re-runs only the copies that didn't complete — successful copies are never re-printed.
- 🔒 Permission-gated — Three permissions (
pipelines:read/pipelines:write/pipelines:run) let you split authoring the recipe from spending filament with it.

🚀 Quick Start
Requirements
- Python 3.10+ (3.11/3.12 recommended)
- Bambu Lab printer with Developer Mode enabled (see below)
- "Store sent files on external storage" enabled in Bambu Studio/OrcaSlicer
- Same local network as printer
Installation
Windows (Native Installer)
Self-contained .exe — no Python, Node, Docker, or Git required on the target machine. The installer bundles Python 3.13, the React frontend, ffmpeg, and registers Bambuddy as a Windows service.
Download the latest installer:
https://github.com/maziggy/bambuddy/releases/latest/download/bambuddy-windows-x64-setup.exe
Run it (one-time UAC prompt — admin install) → Bambuddy starts as a Windows service and the dashboard opens at http://localhost:8000 automatically. Data lives at C:\ProgramData\Bambuddy\, install at C:\Program Files\Bambuddy\. To update, just run a newer installer over the existing install — your database and archives are preserved.
SmartScreen warning: until our SignPath OSS code-signing approval lands, you'll see "Windows protected your PC" on first run. Click More info → Run anyway.
See the Windows Installer Guide for service management, logs, and troubleshooting.

Note: WebSocket support is required for real-time printer updates.
Network Mode Host (required for printer discovery and camera streaming):
services:
bambuddy:
build: .
network_mode: host
Note: Docker's default bridge networking cannot receive SSDP multicast packets for automatic printer discovery. When using
network_mode: host, Bambuddy auto-detects your network subnet and can discover printers via subnet scanning in the Add Printer dialog.
Manual Installation (Linux/macOS)
# Clone and setup
git clone https://github.com/maziggy/bambuddy.git
cd bambuddy
python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt
# Run (--loop asyncio avoids a uvloop TLS bug that can truncate VP FTP uploads)
uvicorn backend.app.main:app --host 0.0.0.0 --port 8000 --loop asyncio
Open http://localhost:8000 and add your printer!
Need detailed instructions? See the Installation Guide
Windows Native Installation
Windows PowerShell (run as Administrator — the installer self-elevates via UAC if not):
powershell -ExecutionPolicy Bypass -Command "iwr -useb https://raw.githubusercontent.com/maziggy/bambuddy/main/install/windows-installer.ps1 -OutFile windows-installer.ps1; .\windows-installer.ps1"
Installs Bambuddy natively on Windows using Git, Python, a virtual environment, separate data/log directories, and optional NSSM Windows Service registration. See the Windows Installer Guide for parameters and unattended-install options.
Enabling Developer Mode
Developer Mode allows third-party software like Bambuddy to control your printer over the local network.
- On printer: Settings → Network → LAN Only Mode → Enable
- Enable Developer Mode (appears after LAN Only Mode is enabled)
- Note the Access Code displayed
- Find IP address in network settings
- Find Serial Number in device info
Note: Developer Mode disables cloud features but provides full local control. Standard LAN Mode (without Developer Mode) only allows read-only monitoring.
Slicer Settings
In Bambu Studio or OrcaSlicer, enable "Store sent files on external storage" so that print files (3MF) are saved to the printer's SD card. Bambuddy needs these files to extract thumbnails and 3D model previews.
- Open Bambu Studio or OrcaSlicer
- Go to the Device tab for your printer
- In Print Options, enable Store Sent Files on External Storage

Contributions welcome! Ways to help:
- 📝 Document — Improve the wiki and guides (urgently needed!)
- Test — Report issues with your printer model
- Translate — Add new languages
- Code — Submit PRs for bugs or features
- 🔒 Security review — (specifically wanted, see below)
Not sure where to start? Reach out on Discord or email martin@bambuddy.cool — I'll help you find something that fits.
🔒 Looking for a security-focused contributor
I'm bringing on a contributor whose specific focus is keeping an eye on Bambuddy's security.
Concretely:
Track the dev branch and flag changes touching auth, permissions, token handling, or the CI security backstops. Async post-merge — no gating of in-flight PRs.
What matters more than formal qualifications: fail-closed thinking by default, comfortable reading the auth layer (FastAPI + SQLAlchemy on the backend, a small React surface), willing to push back on except Exception shapes in security-sensitive code.
No fixed time commitment. If you're interested — or know someone who fits — email martin@bambuddy.cool or DM on Discord.
See CONTRIBUTING.md for guidelines.
