Agents
Keep model calls, tool calls, and approvals safe across crashes, with the native Node or Go agent API or a LangGraph checkpoint saver.
Ironflow is pre-1.0: APIs can change between releases. Pin a version. What is ready →

Ironflow is a durable runtime for AI agents and event-driven systems, in one binary.
Quick start
Read https://ironflow.run/start.md and set up Ironflow in this project.
Paste this into your coding agent. The page tells it to show you each command and wait for your approval. Skills only, without the engine: npx skills add sahina/ironflow-releases

Choose a path
Workflows
Run long processes as durable functions that react to events, wait without holding a worker, and derive views from history.
Four primitives behind both paths
Events
Ordered domain facts that functions and projections react to.
Durable steps
Saved results, so a restarted run skips finished work.
Waits
Pause for an event or approval without holding a worker.
Projections
Read models derived from event history, rebuilt when the view changes.
