Launch HN: Rivet (YC W23) – Scale and Orchestrate Agents on S3
Rivet is a lightweight, scalable orchestrator for agentic workloads that uses the actor model with S3 as its backend.
Key points
- •Instead of running a heavyweight sandbox per agent, each agent is assigned a lightweight actor backed by S3.
- •Actors provide a long-lived process, in-memory state, a WebSocket server, durable SQLite storage backed by S3, and hibernation when idle.
- •The system follows a model similar to Cloudflare Durable Objects.
