C4: a device's `viewers` (superusers by default, or members) covers the image and video messages its ports publish. Anyone else gets none of their values on the socket, in the catalogue or a flow's state, 403 for their history, for the frames they hold (the last 8 included) and for TURN credentials, no bytes when asking for them, and `bye: forbidden` for a live view. A device credential stays bounded by its dashboards. The device page sets it in its Camera section, and a tile the viewer may not see says "No access to this camera" and asks the camera for nothing. C3: - A volatile upload is held to MAX_FRAME_BYTES (4 MiB, 413 above it, read without extra copies), and so is a frame on a device's socket. - A frame the engine holds in memory is written to the ring directory before a local worker is handed it, so load_artifact finds it. - A socket the bus dropped events for catches up with a snapshot, demand included, and a device's credential is checked again per frame, cached by the flow store revision and its nonce, so a lost event never keeps an unpaired device's frames coming. - A report is at most 64 KB once its named config_schemas are put in place. - A device away for 60 s has its true bool messages set to false. - Refused frames are logged by fixed keys, a frame is named after its message, `fluksio serve` waits 5 s for open connections, a tile with a stream URL creates no demand, the 8-name cap keeps the newest names. - Every container's log rotates (json-file, 3 x 10 MB).
Fluksio App
Fluksio is a node-based automation software that brings trust and reliability to your flow. It just works and looks good.
The core of Fluksio: a node-based, test-driven automation software built to scale. This repo holds the FastAPI backend, the flow engine, and the dashboard SPA, built into one image that 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.${DOMAIN}
compose.yml the single container, as the getting-started guide runs it
docker/ the operator stack: compose.yml → compose.dev.yml → compose.local.yml (+ compose.traefik.yml)
scripts/ generate-client.sh, test.sh
Install without Docker
Get started quickly by running
pip install fluksio
fluksio serve
Then, head over to fluksio.com, sign up and add a new instance. Using the code provided, run
fluksio enroll <code>
and you're ready to rock.
Fluksio is distributed at it's heart. A machine that should only run nodes for an engine elsewhere installs less:
pip install fluksio-worker
FLUKSIO_WORKER_TOKEN=… fluksio-worker --url wss://api.fluksio.com/api/v1/workers/attach --labels gpu
Getting started
Needs Docker with Compose v2, on x86-64 or arm64 such as a Raspberry Pi 4 or 5.
docker compose up -d # http://localhost:8080
docker compose logs fluksio # the admin password, printed once
Optional features (MQTT, InfluxDB, mail, …) are build-time extras; see EXTRAS in
compose.yml.
For development, with hot reload behind Traefik on port 80 (also needs make and openssl):
make init # once: .env with generated secrets, `proxy` network, prints the admin login
make dev-local # full stack at http://app.localhost
make down # stop it
Without Docker:
make install # uv sync + bun install
make dev-utils # proxy and mailcatcher only
make dev-backend # FastAPI on :8000, hot reload
make dev-frontend # Vite on :5173
make test # pytest + Playwright (the e2e half on its own stack, behind make dev's Traefik)
make lint # ruff + mypy + biome
make generate-client # regenerate the frontend SDK from the OpenAPI schema
make help lists every target.
Documentation
The public site lives in docs/ and is built with zensical:
make docs-serve # live preview on :8000
make docs # static build into ./site
It is served at docs.${DOMAIN} by the docs service in docker/compose.yml,
and .gitea/workflows/docs.yml builds it with --strict on every push.
