Geyser Developer Platform

Geyser is a framework-neutral control plane for durable agentic work. The public SDK talks to a versioned API; it is not an Agent runtime and does not include or grant a model, brain, provider, browser, tool, credential, policy, or deployment authority.

Start with the five-minute emulator quickstart, then read authentication and projects, SDK clients, and the CLI reference. Exact implemented, published, qualified, production-enabled, and observed-deployed status is recorded separately in the compatibility matrix.

Release consumers should also read release verification and supply-chain trust, including the immutable-artifact, yank, compromise, and revocation policy.

Public authorities

• GitHub — source, examples, conformance, and releases.
• PyPI SDK and PyPI CLI — Python distribution authority.
• Homebrew tap — standalone CLI authority.
• Compatibility status — implemented, published, qualified, production-enabled, and observed-deployed facts.

Production release

Version 0.1.0 supports Python 3.11–3.13. Standalone qualification is limited to Apple-silicon macOS and Ubuntu 24.04 AMD64. A local emulator pass does not grant production capability or authority.
