About Stagehand
Stagehand is an open source SDK for browser agents, built by the Browserbase team. It offers Playwright-style methods along with natural language actions such as act, observe and extract.
What it does
Developers call familiar methods such as goto, click and locator in TypeScript, Python or Go. They can also describe an action in plain language and get structured data back. When a site changes, the library detects the change and refreshes how the action is found, so scripts need less upkeep. It runs as an extension beside the browser to cut round-trip delay.
Key features
- Playwright-style browser methods
- Natural language act, observe and extract
- Self-healing actions when sites change
- TypeScript, Python and Go support
- OpenTelemetry support
Who it's for
Developers who already know Playwright and want agent-friendly browser control with less maintenance. Teams that run browser automation in production can use the telemetry hooks to monitor it.
Pricing and good to know
The library is open source under the MIT licence. The project links to docs, evals and a showcase of example projects. It works best when you test its actions against the sites you care about, since page layouts change over time.
Highlights
- Use Playwright-style methods like click and goto
- Describe actions in plain language
- Recover actions when page layouts change
- Write code in TypeScript, Python or Go
- Send traces through OpenTelemetry
