bus factor 2 concentrated

top-author share 32% 6 mo

bus factor = how many people it takes to cover more than half the commits (6 months). 1 is a solo project; higher means the work is spread across a team. top-author share is the single busiest author's slice of those commits.

why it's a big deal

Gives developers durable execution so application code is guaranteed to run to completion, recovering partial progress after crashes without re-running steps that already finished.
Removes the need to hand-build fault-tolerance across microservices, serverless functions, event pipelines, and AI agents, since retries, exactly-once delivery, and persistent state are handled by the platform.
Targets teams building durable AI agents, microservice orchestrations, event processing, async task pipelines, and stateful serverless apps.

under the hood

Written almost entirely in Rust, with polyglot SDKs for TypeScript, Java, Kotlin, Python, Go, and Rust.
Combines durable execution with reliable request-response, one-way, and scheduled messaging at exactly-once semantics, plus per-entity key-value state persisted alongside execution progress.
Ships as prebuilt binaries, Homebrew, npm, and Docker with a built-in UI, CLI, and OpenTelemetry tracing, and supports serverless deployment.
