The orchestrator for agentic workloads. A fast, high-density and scalable orchestrator for every workload an agent needs.
Rivet is a Rust-based orchestrator for agentic workloads, built around 'Actors' — long-lived processes with in-memory state, a SQLite database, WebSockets, and scheduling. Actors share node processes for high density (72 KB each, ~5 ms p99 cold starts), and all data is stored in S3, letting clusters scale to billions of Actors that hibernate when idle and wake on demand.
Why now: They launched on Hacker News (Launch HN: YC W23) showcasing an S3-backed architecture claiming SSD-speed durability at ~10x lower cost, directly relevant to the current wave of durable AI-agent infrastructure.
Who it is for: Developers building AI agents, multiplayer/realtime apps, workflows, or collaborative tools that need durable per-user/per-session state at scale.
