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.
The versioned filesystem built for AI agents
A 100% POSIX-compatible mount so agents and sandboxes use familiar Unix tools, with persistence, sync and version history handled transparently underneath.
Fork a workspace in milliseconds to run dozens of agents on isolated branches, then pick the best result without file locking.
Snapshot the entire filesystem at every step and restore any past state with a single API call when an agent goes off track.
Pause any agent for review, build approval queues and policy gates, then resume from the exact same workspace state.
