`resources` was reachable from the SDK and the API and nowhere else, and `node_queued` was published to nothing at all — so a node waiting for a machine looked exactly like a node that had hung, which is the failure the event was added for. The node panel gets a Resources section: a size by name, the numbers for a node that wants its own, and how long it is expected to take. Picking a flavor drops the numbers, because saying both is two answers and the engine refuses it. A queued node draws a neutral dot rather than one of the three status colours — it is not running, it did not go well, and it did not go wrong; it is idle with a reason, which the tooltip gives. And a Workers screen, which is the first UI for any of this: every machine the engine can reach with what is free of each, what is attached, what a cluster has been asked for, and the sizes, editable. `fluksio status` grew a line of the same. The demo's training node already preferred a GPU worker, which was exactly the declaration that used to be dropped, so it now says how much of that machine it takes as well.

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. It is served on
app.${DOMAIN} (SPA) and api.${DOMAIN} (API)
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.${DOMAIN}
docker/ compose.yml → compose.dev.yml → compose.local.yml (+ compose.traefik.yml)
scripts/ generate-client.sh, test.sh
Install without Docker
Get started quickly by running
pip install fluksio
fluksio serve
Then, head over to fluksio.com, sign up and add a new installation. Using the code provided, run
fluksio enroll <code>
and you're ready to rock.
Fluksio is distributed at it's heart. A machine that should only run nodes for an engine elsewhere installs less:
pip install fluksio-worker
fluksio-worker --url wss://api.example.com/api/v1/workers/attach --token "$TOKEN" --labels gpu
Getting started
Normally driven from the workspace root (make init once, then make dev). Standalone:
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 needs the stack up)
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.
