Make work flow.
Fluxion is a BPMN 2.0 workflow engine in Rust. Build dependable processes, ship them as a single service, and keep every moving part in view.
Less plumbing.
More doing.
When a process gets complicated, your runtime shouldn’t. Fluxion gives every task, decision, event, and variable a clear place to go.
From a single binary to a distributed cluster, the same BPMN graph stays readable, observable, and ready for production.
Fast where it
counts.
Rust means no JVM warm-up and no surprise garbage-collection pauses. Fluxion starts in milliseconds and keeps latency predictable from the first request.

Import a BPMN 2.0 diagram and Fluxion turns it into an executable workflow graph. Service tasks, user tasks, gateways, timers, and messages all speak the same language.

Fluxion ships as a single binary with a REST API. Bring your own PostgreSQL or use the included Compose file.
