# Fluksio

> Fluksio is a node-based automation engine. A flow is a graph of small
> functions wired by message name, kept running by one resident engine. The
> same engine serves two shapes of work: live flows that never end (buildings,
> labs, homelabs) and batch runs that finish and leave a record (experiments,
> ML pipelines, CI-style jobs). Self-hosted by default; an optional portal
> exists only to reach an instance that has no inbound route.

## Getting started
- [Pick your starting point](/getting-started/): the two setup paths and how to choose
- [Data science](/getting-started/data-science/): pip install, wrap a training script, runs and sweeps
- [Facility automation](/getting-started/facility-automation/): Docker stack, MQTT to dashboard, InfluxDB, workers

## Concepts
- [Flows, nodes and messages](/concepts/flows/): the graph comes from message names, not drawn wires
- [Where a node's values come from](/concepts/values/): ports, settings, flow inputs
- [Keeping state in a flow](/concepts/state/): a message a node both reads and writes
- [Runs: pipelines that finish](/concepts/runs/): batch mode, metrics, artifacts, sweeps, durability

## The interface
- [The dashboard app](/interface/): the shell, Home, health and activity
- [The flow editor](/interface/flow-editor/): canvas, node panel, dock, shortcuts, drafts
- [Dashboards and panels](/interface/dashboards/): widgets, typed bindings, wall screens
- [Secrets, modules and alerts](/interface/operations/): credentials, packages, failure routing
- [Accounts and the portal](/interface/portal/): enrolment, remote users, revoking

## Code and the CLI
- [The fluksio command](/code/cli/): serve, enroll, worker, and the data directory
- [Writing node code](/code/nodes/): process(), generators, fluksio.emit, artifacts
- [The HTTP API](/code/api/): auth, flows, messages, runs, observability, websocket
- [Remote workers](/code/workers/): fluksio-worker, device labels, artifacts across hosts
- [Agents over MCP](/code/agents/): the tool list and the security model

## Reference
- [Node types](/reference/node-types/): every built-in type and its settings
- [Payload types](/reference/payload-types/): float, int, str, bool, json, record, list, series, artifact
- [Configuration](/reference/configuration/): every environment variable
