The TypeScript framework for building, deploying, and observing AI agents
Define agents with instructions, models, tools, and runtime behavior, then compose typed workflow steps with retries and branching in TypeScript.
Give agents long-lived context with observational memory, semantic recall, and thread-aware storage.
Traces, metrics, logs, and datasets show every model call, tool call, and handoff in a searchable timeline.
Score agent runs against repeatable checks and experiments before changes reach production.
Run and scale durable AI agents on your own infrastructure
Every Actor gets a SQLite database and a filesystem, so an agent's memory and progress survive restarts and idle periods without a separate database.
Run untrusted or AI-generated code on your own infrastructure with fine-grained control over network access, filesystem permissions, and resource limits.
A node failure reschedules its Actors elsewhere with state intact, and multi-step work replays after a crash — with no checkpointing harness to build yourself.
Address an Actor directly over HTTP or hold a live WebSocket, and use the React SDK to subscribe components to an Actor's state in real time.
