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.
A model-agnostic Ruby framework for building AI agents and automations
Use OpenAI, Claude or Gemini — or plug in your own provider — without locking your app to one model.
Reusable classes for single generation tasks such as code from description or a description from code.
Operations that supply inputs to or act on the output of generators, like writing a file or running a command.
Autonomous entities with triggers such as file changes or time intervals — for example an agent that runs tests and fixes failing code.
