The channel sends through the Bot API with httpx only: HTML with escaped text, cut to fit a message, silent for a warning, a short 429 waited out once, and errors that say what to do about a blocked bot, a lost chat or a bad token and never quote the request URL. The bot token is a stored secret: saving a channel refuses a literal one, the card's "Store token" writes the secret and a reference, and no endpoint returns it. A chat id is never typed. Connect starts a ten minute code, and the chat that sends `/start <code>` back through the bot is the one connected, so it is a chat somebody opened a link for. The engine fetches updates only while a code is waiting (no standing poll, no webhook, no inbound address) and ignores everything else without a reply. Connect needs a saved form, and the form takes the connected chat in without touching what was typed since. The token is part of every Bot API URL, so the httpx logger gets the same filter the request lines have, which now also masks an httpx.URL argument.
Fluksio App
Connect a few nodes, give their messages names, and let Fluksio handle the running. Use live flows for automation and batch runs for experiments, with dashboards to see what happened.
This repository holds the FastAPI backend, flow engine and dashboard SPA. The Docker image serves all three on one port.
Layout
backend/ FastAPI + SQLModel + Alembic + SQLite
fluksio/flow/ the flow engine (nodes, pipeline, state backends, controller)
fluksio/cli.py `fluksio serve` / `enroll` / `worker`
worker/ the `fluksio-worker` distribution: the agent and the node runner
frontend/ React 19 + TanStack Router + Tailwind 4 + shadcn/ui
docs/ the public documentation site (zensical), served on docs.${DOMAIN}
compose.yml the single container, as the getting-started guide runs it
docker/ the operator stack: compose.yml → compose.dev.yml → compose.local.yml (+ compose.traefik.yml)
scripts/ generate-client.sh, test.sh
Install without Docker
Start an engine with Python 3.12 or newer on Linux or macOS:
pip install fluksio
fluksio serve
For the optional browser portal, sign up at fluksio.com and add an instance. Use the code it gives you:
fluksio enroll <code>
Your engine also works without enrollment. A machine that only runs nodes for another engine needs just the worker package:
pip install fluksio-worker
FLUKSIO_WORKER_TOKEN='<worker-token>' fluksio-worker \
--url wss://fluksio.example.com/api/v1/workers/attach --labels gpu
Replace the example address with your engine's URL and create a token as described in Remote workers.
Getting started
Needs Docker with Compose v2, on x86-64 or arm64 such as a Raspberry Pi 4 or 5.
docker compose up -d # http://localhost:8080
docker compose logs fluksio # the admin password, printed once
Optional features (MQTT, InfluxDB, mail, …) are build-time extras; see EXTRAS in
compose.yml.
For development, with hot reload behind Traefik on port 80 (also needs make and openssl):
make init # once: .env with generated secrets, `proxy` network, prints the admin login
make dev-local # full stack at http://app.localhost
make down # stop it
Without Docker:
make install # uv sync + bun install
make dev-utils # proxy and mailcatcher only
make dev-backend # FastAPI on :8000, hot reload
make dev-frontend # Vite on :5173
make test # pytest + Playwright (the e2e half on its own stack, behind make dev's Traefik)
make lint # ruff + mypy + biome
make generate-client # regenerate the frontend SDK from the OpenAPI schema
make help lists every target. See Development for stack
options and checks.
Documentation
The public site lives in docs/ and is built with zensical:
make docs-serve # live preview on :8000
make docs # static build into ./site
It is served at docs.${DOMAIN} by the docs service in docker/compose.yml,
and .gitea/workflows/docs.yml builds it with --strict on every push.
