Orch8 — Durable Workflow Engine for AI Agents
Durable Workflow Engine for AI Agents
The short version
What is Orch8 — Durable Workflow Engine for AI Agents?
Orch8 is a durable workflow engine designed to checkpoint long-running workflows across crashes, deployments, human approvals, and connectivity issues. It allows workflows to resume from the last completed boundary rather than replaying the entire process. The engine is built in Rust and can run on servers or be embedded in mobile devices.
Orch8 provides a single Rust runtime that operates on both servers and offline-capable mobile devices, enabling durable execution state management where handlers own the business logic and the engine owns the state.
