Stagehand

Stagehand is an SDK for browser agents that provides a Playwright-style API, self-healing selectors, and multi-language support.

Stagehand is an SDK built specifically for browser agents to control web pages efficiently. It combines familiar Playwright-style methods like goto, click, locator, and screenshot with self-healing actions and natural language commands. The software uses hybrid accessibility tree trimming to reduce token usage and runs as an extension inside the browser to lower latency. It supports complex DOM structures such as out-of-process iframes and closed Shadow DOMs across TypeScript, Python, and Go. Developers use it to build reliable browser agents that handle website changes automatically and execute tasks faster in production.
