What OpenBrowser is

OpenBrowser is a free, MIT-licensed framework for browser automation in which an LLM writes Python code to navigate pages, interact with them, and extract information. It communicates with browsers through Chrome DevTools Protocol and can analyze screenshots. Its MCP server provides one execute_code tool that runs Python in a persistent namespace. The maker lists integrations with LLM providers and MCP clients, including Claude Code, Cursor, Windsurf, VS Code, and n8n. Browser sessions can be recorded and replayed, then exported to Jupyter notebooks or API crawler code. Listed uses include research, scraping, form filling, end-to-end testing, page analysis, accessibility audits, and file downloads. The project provides installation instructions for Windows, macOS, and Linux, and supports Docker, Kubernetes, and cloud deployment. A hosted version is offered through a waitlist; described features include a web interface, real-time VNC streaming, saved logins, scheduled workflows, and email notifications. The repository says hosted saved logins are KMS-encrypted.

Who it suits

OpenBrowser may suit developers and teams building browser automations with LLMs, MCP clients, or n8n. Its listed uses also include research, scraping, testing, and accessibility audits.

What it does well

  • Free and MIT licensed.
  • Records and replays browser sessions.
  • Exports sessions to notebooks or crawler code.
  • Offers Windows, macOS, and Linux installation instructions.
  • Supports Docker, Kubernetes, and cloud deployment.

What to know first

  • Hosted access is offered through a waitlist.
  • The MCP server exposes one execute_code tool.
  • The hosted version is not presented as generally available.

Getting started

  1. Visit the OpenBrowser website or repository
  2. Install it on Windows, macOS, or Linux
  3. Use an existing Chrome, Edge, Brave, or Chromium browser
  4. Allow automatic Chromium installation on first run when uvx is available
  5. Connect an MCP client or use the execute_code tool
  6. Deploy with Docker, Kubernetes, or cloud infrastructure if required

Verdict

OpenBrowser combines Python-based browser automation with MCP integrations and session exports. Consider whether its single-tool interface and waitlisted hosted option suit your workflow.
