+Kernel's browsers are compatible with all browser and Computer Use frameworks.
+
+## Universal compatibility
+
+Kernel browsers work with any framework or tool that supports the Chrome DevTools Protocol (CDP). This means you can:
+
+- **Use any agent framework**: Integrate with popular frameworks like Browser Use, Stagehand, Playwright, Puppeteer, Selenium, and more
+- **Connect via CDP**: All browsers expose a CDP WebSocket URL for direct connection
+- **No vendor lock-in**: Switch between frameworks or use multiple frameworks simultaneously
+- **Standard protocols**: Built on open standards that work with the entire browser automation ecosystem
+
+## Popular Framework Integrations
+
+Kernel provides detailed guides for popular agent frameworks:
+
+- **[Browser Use](/integrations/browser-use)** - Python-based AI browser agent framework
+- **[Stagehand](/integrations/stagehand)** - AI browser automation with natural language
+- **[Computer Use (Anthropic)](/integrations/computer-use/anthropic)** - Claude's computer use capability
+- **[Computer Use (OpenAI)](/integrations/computer-use/openai)** - OpenAI's computer use capability
+- **[Magnitude](/integrations/magnitude)** - AI-powered web automation
+- **[Val Town](/integrations/valtown)** - Serverless function runtime
+- **[Vercel](https://github.com/onkernel/vercel-template)** - Deploy browser automations to Vercel
+
+## Custom Integrations
+
+Kernel works with any tool that supports CDP. Check out our [browser creation guide](/browsers/create-a-browser) to learn how to connect any other agent framework.
