Build something your team can use

Geyser brings people and AI agents together with computers, connected apps, and shared projects. The developer tools let you extend what those agents can do and build applications around their work.

Start locally. Create a tool, test its behavior, and follow a run from request to result. When you're ready, connect to your Geyser workspace with the same SDK and CLI.

What is open

The Python SDK, CLI, local emulator, schemas, and examples are MIT-licensed in Geyser Open. Use them with your existing application or agent framework. The SDK connects to Geyser's API; your workspace supplies the Agent runtime, models, tools, and access.

What you can build on

A task describes the work. A run tracks its execution. Ordered events let your application follow progress and reconnect after an interruption. Checkpoints preserve a known point in the work. Approvals bind a person's decision to a specific action, and effects record what that action did.
