Score: 8.0/10 (Innovation: 7, Technical: 9, Documentation: 8, Utility: 8)

Orch8 is a self-hosted durable workflow orchestration engine in Rust that runs as a single binary with only Postgres or SQLite as a dependency, providing strong reliability features like state snapshots, retries, dead-letter queues, and crash recovery. It stands out for combining enterprise-grade workflow primitives (Parallel, Race, TryCatch, AI agent support) with minimal operational overhead, making it a promising alternative to heavier systems like Temporal or Airflow.

Target audience: backend devs, devops, data engineers
