Bot accounts (User rows with is_bot=True), scoped API tokens (read:messages, write:messages, manage:rooms) authenticated via Authorization: Bearer on both REST and the WS handshake, live bot WebSocket access on the same /ws/chat endpoint humans use, message editing (WS "edit" envelope -> message_update broadcast, fans out cross-instance for free via the existing broadcaster), incoming webhooks (room-scoped, no auth beyond the URL token), and outgoing webhooks/event subscriptions (HMAC-SHA256 signed, backgrounded delivery, creation-time SSRF validation against private/loopback/link-local targets). Token auth is additive, not a parallel system: a bearer-token-authenticated bot goes through the exact same room-membership/role checks a session- authenticated human does everywhere; only read:messages/write:messages are separately scope-gated (the two message endpoints). manage:rooms scope enforcement, full per-delivery SSRF re-validation, and bot API rate limiting were explicitly scoped out (confirmed with the repo owner) as disproportionate to this phase -- documented as known gaps in backend/README.md rather than silently skipped. Admin portal gains a Bots tab (create bots, issue/revoke scoped tokens, cross-room webhook visibility); RoomInfoPanel gains room-scoped webhook/ subscription management, mirroring how invites already work there. The chat UI also gets a minimal "edit your own message" affordance -- not asked for by the issue, but the only practical way to exercise the edit pipeline by hand instead of only via a scripted bot client. Along the way: fixed a real bug caught while writing the incoming-webhook test -- offline-push notification relied on the sender being "connected" to exclude themselves, true for WS-originated messages but not for the new webhook path, which has no WS connection for the attributed sender at all. Now explicitly excluded. Also discovered the REST-only test fixture never triggered ASGI lifespan, so app.state.broadcaster/presence didn't exist for it; moved their construction out of the lifespan into create_app() itself (Redis client construction is synchronous/lazy) so both the WS and REST-only paths always have them. New tests/test_bots.py, test_message_edit.py, test_webhooks.py (full suite now 78/78, stable across repeated runs) plus a scripted end-to-end smoke test (bot WS join/post/edit, incoming webhook, SSRF rejection, outgoing delivery) and a full browser walkthrough of the new admin/room UI.

KeepItTalking
A web-based team chat service (Mattermost-style, no threaded conversations), invite-only. See ARCHITECTURE.md for the full system design and phased build plan.
Phase 1: auth, open-room CRUD, and single-instance WebSocket chat, backend
- a minimal frontend. Phase 2: private rooms, room roles (owner/admin/ member), and room invites — backend only, see below. Later phases (push notifications, Redis fan-out, the admin portal, the bot/extension system, and production deployment) are tracked as issues in the repo's issue tracker, prioritized.
Structure
backend/— FastAPI + SQLAlchemy 2.0 (async) + PostgreSQL. Seebackend/README.mdfor local setup, migrations, how to create a user (site registration is invite-only — no public sign-up endpoint), and the Phase 2 room-roles/invites API.frontend/— React + Vite PWA (login, room list, chat view). Still Phase-1-only: it doesn't yet call any of the Phase 2 endpoints. A UI redesign is happening separately; frontend work resumes once that lands.
Quickstart
# 1. Postgres (see backend/README.md for details)
docker run -d --name chatapp-postgres \
-e POSTGRES_USER=chatapp -e POSTGRES_PASSWORD=chatapp -e POSTGRES_DB=chatapp \
-p 5432:5432 postgres:16-alpine
# 2. Backend
cd backend
python3 -m venv .venv
.venv/bin/pip install -e ".[dev]"
cp .env.example .env # then set SESSION_SECRET
.venv/bin/alembic upgrade head
.venv/bin/python -m app.cli create-user alice alice@example.com "some-password"
.venv/bin/uvicorn app.main:app --reload &
# 3. Frontend (in another shell)
cd frontend
npm install
npm run dev
Then open http://localhost:5173 and log in with the account created above.
The Vite dev server proxies /api and /ws to the backend on :8000, so no
CORS configuration is needed in development.
Deployment
Not part of Phase 1. The target is two plain Linux servers with no containers — see ARCHITECTURE.md §9 and the corresponding "Production deployment" issue in the tracker.
