  Browser Use

  Browser Use

  Open-source browser automation for AI agents.

  MIT-licensed Python framework that connects AI agents to a real browser to navigate, fill forms, extract data, and run multi-step web workflows. It parses the live DOM into a structured view so any model — Claude, GPT, Gemini, Qwen, DeepSeek — can act on it. A hosted Browser Use Cloud adds managed sessions and a fully-hosted agent.

  Worth knowing: Built by two ETH Zurich founders in YC's W25 batch; raised a $17M seed led by Felicis in March 2025.

  Skyvern

  Automate browser-based workflows on any website with AI.

  An AI agent that completes browser workflows — form fills, logins, data extraction, multi-step flows — by combining computer vision with LLMs rather than hand-written selectors, so a single agent generalizes across sites it has never seen. Run it via the cloud app and API or self-host the open-source engine; bring your own model (OpenAI, Anthropic, Gemini, or local Ollama).

  Worth knowing: A Y Combinator S23 startup founded by ex-Faire and ex-Lyft engineers Suchintan Singh and Shuchang Zheng.

  Playwright MCP

  Microsoft

  Microsoft's official MCP server for browser automation, driven by Playwright.

  An open-source Model Context Protocol server from Microsoft that lets LLMs and agents browse and act on the web through Playwright. It exposes 40+ tools for navigation, forms, clicking, network mocking, tracing, and more, operating on structured accessibility snapshots rather than pixels so each interactive element gets a deterministic ref. Works with Claude, VS Code, Cursor, Windsurf, and any MCP client.

  Worth knowing: Maintained by Microsoft's own Playwright team, it's one of the most-starred MCP servers on GitHub (~33k stars).

  Nen Labs

  Open-source browser API for AI agents and apps.

  A batteries-included headless-browser sandbox that lets AI agents automate the web without managing browser infrastructure. Steel handles sessions, cookies, proxy rotation, CAPTCHA solving, and page-to-markdown/screenshot/PDF conversion behind a single API, built on Puppeteer and the Chrome DevTools Protocol. Run the open-source image locally via Docker or use Steel Cloud's managed browser fleet.

  Worth knowing: Operated by Nen Labs, which has raised about $17M to date for its open-source browser infrastructure.
