Rivet: Fast, high-density, scalable orchestration for agentic workloads (6.5k stars)
What it does
All text below is quoted directly from the project README.
>Rivet Actors are the primitive for stateful workloads. Built for AI agents, collaborative apps, and durable execution.
What is Rivet?
- 72 KB per Actor: An Actor lives inside a node process you already run, not in its own container or VM.
- 6.9 ms cold starts: A cold start includes scheduling the Actor, creating its storage, and serving the first request. No image pull, no container boot.
- Billions of Actors on one control plane: Actors are scheduled independently, so adding capacity means adding machines.
- Hibernates when idle, wakes on demand: An idle Actor writes its state and unloads. The next request brings it back in 4.4 ms with nothing lost.
- Keep state with each Actor: Every Actor gets its own SQLite database and key-value storage.
- One Rust binary and a bucket: There is no database to run and no message bus.
- Run code agents generate at runtime: Each piece of new, untrusted code gets an Actor of its own, with its own database and filesystem and no reach into anyone else's.
- Works with the tools you already use: Typed SDKs for your backend and React hooks for your frontend.
