Chrome DevTools MCP vs SeleniumBase MCP
Two MCP servers from our browser automation ranking, compared on live data - updated nightly, never sponsored.
Bottom line · 2026-09-18
Chrome DevTools MCP records significantly more monthly package installs (9,332,843 vs 2,076,176); both are actively maintained, with commits inside the last month.
How they differ in kind
Chrome DevTools MCP focuses on: Chrome DevTools for agents (chrome-devtools-mcp) lets your coding agent (such as Antigravity, Claude, Cursor or Copilot) control and inspect a live Chrome browser. SeleniumBase MCP focuses on: All-in-one Browser Automation Framework: Web Crawling / Testing / Scraping / Stealth. Implementation languages differ (TypeScript vs Python).
What each one does
Chrome DevTools MCP
Chrome DevTools for agents (chrome-devtools-mcp) lets your coding agent (such as Antigravity, Claude, Cursor or Copilot) control and inspect a live Chrome browser. It acts as a Model-Context-Protocol (MCP) server, giving your AI coding assistant access to the full power of Chrome DevTools for reliable automation, in-depth debugging, and performance analysis.
