## Description

Build a graph once, compile it into an immutable runner, and resume from append-only checkpoints.

## Where it fits

Flow is useful on its own when a Go application needs compiled graphs, typed interruption, checkpointing, and resumable execution. Within Looprig, [Workflows](/docs/modules/workflows.md) builds durable workflow services on Flow, while [Flow Store](/docs/modules/flow-store.md) persists checkpoints. Flow owns graph execution, not agent sessions or the backing storage engine.
