Sources and review

Checked against public documentation on . Suitability guidance is our editorial judgment; this is not a performance benchmark or an endorsement.

Publisher documentation

Choose the runtime, model and browser deployment

Stagehand v4 documents AI actions, extraction and observation alongside deterministic page control, with TypeScript, Python and Go SDKs. Local Chrome and hosted browser sessions have different setup requirements; the SDK alone does not supply every operating dependency.

Use the selected SDK's current installation guide and configure the browser and model path explicitly. Model inference and optional hosted browser usage can incur separate costs. ASE has not installed the SDK, started a hosted session or tested a browser task.

Documentation checked · Review due

The review date is an ASE reminder, not an upstream guarantee.

Best for

Developers building browser agents who want code-level control alongside natural-language actions and structured extraction.

Avoid if

You need a complete no-code workflow product or cannot use model-assisted browser actions.

About Stagehand

Stagehand is a browser automation SDK from Browserbase. It combines code-driven browser control with model-assisted actions, extraction and observation. The SDK is open source; model calls and hosted browser sessions can have separate costs. It is distinct from the Browserbase hosted platform.

Stagehand is listed in this index, with 26k stars on GitHub. Its latest recorded repository push was in October 2026; that is not an ASE editorial review date.
