KERNEL

KERNEL is crazy fast, open-source infrastructure for AI agents to access the internet — trusted by Cash App, Framer, and 3,000+ teams.

We spin up sandboxed cloud browsers in under 30ms (benchmarked 5.8x faster cold starts than the nearest competitor), with agent-native features out-of-the-box: automatic agent authentication & session reuse, bot anti-detection, CAPTCHA auto-solvers, live views, MP4 session replays, and browser telemetry streams. Create hundreds of browsers in parallel without managing infrastructure. Compatible with CUA models OpenAI, Anthropic, Gemini, Yutori, and more.
