Our top 3 Browserbase alternatives
Browser Use is an open-source Python library and hosted platform that enables AI agents to control web browsers programmatically. It lives in the AI agent and browser automation ecosystem, built on Playwright and designed to let LLMs interact with websites as a human would—clicking, filling forms, solving CAPTCHAs, and navigating dynamic interfaces. The project provides three deployment paths: a fully hosted cloud service, a command-line interface for existing agents, and a local Python library for custom integrations.

Playwright is a web automation and testing framework published on npm and maintained under the Apache-2.0 licence. Its central promise is one API for three browser engines: the README pins Chromium 154.0.8037.0, Firefox 156.0, and WebKit 26.6, and the same code path drives all of them. The project ships as several entry points rather than one product — Playwright Test as a full-featured end-to-end test runner, Playwright CLI for coding agents, Playwright MCP for LLM-driven automation, Playwright Library for plain automation scripts, and a VS Code extension for authoring and debugging. Documentation and the API reference live at playwright.dev.

Stagehand is a browser automation SDK that puts a model behind three verbs — `observe()`, `act()`, and `extract()` — so an agent can locate elements, work through a flow, and return structured data from the page. It ships as the `@browserbasehq/stagehand` package for TypeScript, a Python package, and a Go module at `github.com/browserbase/stagehand/packages/sdk-go/v4`. It runs against a browser started with `localBrowser.launch({ userDataDir: "./browser-data" })` or against a cloud browser, and it drives headless Chrome over the Chrome DevTools Protocol (cdp). Model configuration is explicit, for example `modelName: "openai/gpt-5.4-mini"` with an API key passed through the environment.
