Kernel is browser infrastructure for AI agents and web automations. Founded in 2025 by Catherine Jue (CEO) and Rafael Garcia (CTO) and backed by Accel and Y Combinator (S25), Kernel runs sandboxed Chromium browsers on a unikernel platform with sub-150ms cold starts, built-in stealth mode, residential proxies, CAPTCHA solving, session recording, live view, persistent profiles, and a serverless app platform that co-locates agent code with browsers. Kernel works with Playwright, Puppeteer, Browser Use, Stagehand, Magnitude, Notte, and the Anthropic/OpenAI/Gemini computer-use loops. The REST API at api.onkernel.com exposes browsers, browser pools, profiles, proxies, replays, extensions, computer controls, filesystem, processes, Playwright execution, managed auth, credentials, apps, deployments, invocations, and projects.
