Browserbase

Summary

Browserbase is a cloud platform giving AI agents real headless browsers plus search, fetch, proxies, verified identity and a model gateway behind one API key. It also runs managed browser agents and ships the open-source Stagehand SDK.

Best for: Developers building browser agents who want one API instead of managing browser infra
Not for: Teams that need the fastest possible cold starts or free anti-detection out of the box: independent benchmarks show Browserbase's session start (5-10s) trailing Kernel and TinyFish, and its free tier ships with no stealth features at all, unlike Kernel's free tier which includes basic stealth and residential proxies.

What it does

Writes code: PartlyGenerates Stagehand browser-automation scripts from a completed Agent run; not general application code.Use the Optimize tool to turn a completed Agent run into a reusable Stagehand script. Optimize reads the run's steps and generates code that follows…docs.browserbase.com/platform/agents/ge…
Debugs and fixes: PartlyDocuments a CI recipe where a coding agent inspects the live DOM on Browserbase and fixes broken selectors; the fix comes from Claude Code, not Browserbase.This GitHub Action creates a Browserbase session, lets Claude Code inspect the live DOM, and opens a PR with fixed selectors.docs.browserbase.com/integrations/skill…
Writes tests: NoTesting docs cover running end-to-end tests on hosted browsers; no page describes authoring tests.Run end-to-end browser tests in consistent, isolated cloud environments. Browserbase gives you reliable infrastructure for automated testing…docs.browserbase.com/use-cases/building…
Ships it: YesBrowser automations are deployed as hosted Functions, published and invoked from the CLI or API.browse functions publish index.tsdocs.browserbase.com/integrations/skill…
