ActorCore

The easiest way to build stateful, AI agent, collaborative, or local-first applications. Deploy to Rivet, Cloudflare, Bun, Node.js, and more.

• Long-Lived, Stateful Compute: Each unit of compute is like a tiny server that remembers things between requests – no need to reload data or worry about timeouts. Like AWS Lambda, but with memory and no timeouts.
• Durable State Without a Database: Your code’s state is saved automatically—no database, ORM, or config needed. Just use regular JavaScript objects or SQLite (available in April).
• Blazing-Fast Reads & Writes: State is stored on the same machine as your compute, so reads and writes are ultra-fast. No database round trips, no latency spikes.
• Realtime, Made Simple: Update state and broadcast changes in realtime. No external pub/sub systems, no polling – just built-in low-latency events.
• Store Data Near Your Users: Your state lives close to your users on the edge – not in a faraway data center – so every interaction feels instant.
• Serverless & Scalable: No servers to manage. Your code runs on-demand and scales automatically with usage.
