I built this TypeScript agent framework to make it easier to build AI agents that are type-safe end-to-end (client to server). It also lets you package common runtime behavior as plugins and reuse them across agents, like auth, rate limits, and sandboxing (e.g. Daytona, E2B, or other sandbox providers). It’s fully event-driven.

Most setups I tried didn’t handle end-to-end typing well, didn’t fit cleanly into an existing app, or made it hard to reuse behavior across agents. This tries to keep things consistent across client and server, make plugins easy to share, and support stateful, resumable runs without a lot of glue code.
