Cotlet gives you your own Chrome in the cloud, the Cloud Browser. You sign in there once to the web apps that have no official API, or only a narrow one, and enable them for your agents. Your AI agent then works in your own account 24/7, even when your computer is off. Password saving is off, so Cotlet never saves your password.

  • One MCP server for every app: https://cotlet.dev/mcp/v1. Works with Claude, ChatGPT, Cursor, Codex, GitHub Copilot, Gemini, Windsurf, n8n and any MCP client.
  • A REST API with the same actions for scripts: https://cotlet.dev/api/v1. One key for both.
  • Your browser, driven by your agent over Chrome DevTools (Playwright, Puppeteer, chrome-devtools-mcp) when no tool does the job.
  • 192 apps today, including Skool, Substack, Booksy, Pirate Ship, Partiful, Milanote, Udemy, GetYourGuide, Idealista and Zendesk. Each is tested every 6 hours.
  • No stored passwords, no CAPTCHA solving, no MFA bypass. Every background request is listed. Hosted in the EU.
