Managed browser infrastructure purpose-built for AI agents — spin up isolated Chrome sessions in seconds, with recording, captcha handling, and persistent state.
Kernel (onkernel.com) is a browser-as-a-service platform designed specifically for AI agents that need to interact with the web. Instead of engineering your own headless Chrome pool, dealing with fingerprint evasion, or wrestling with rotating proxies, developers hit a single API to launch a fresh Chrome session, connect via CDP, Playwright, or Puppeteer, and get back structured artifacts like video recordings, HAR files, DOM snapshots, and screenshots. Kernel handles the messy operational plumbing — Cloudflare/hCaptcha challenge solving, residential proxy rotation, session persistence for logged-in workflows, and per-tenant isolation — so agent developers can focus on task logic. It integrates cleanly with popular agent frameworks including Browser Use, Stagehand and LangChain, and exposes hooks for MCP so an LLM host such as Claude Desktop or Cursor can call Kernel-managed browser tools directly. Common patterns include running long-horizon research agents, executing checkout flows on behalf of users, scraping behind auth walls without triggering bot defenses, and orchestrating fleets of parallel browsers for training data collection. Pricing is usage-based on browser-minutes, with a free hobby tier for prototyping and volume discounts for high-throughput customers. The platform's replay UI makes debugging non-trivial agent trajectories dramatically easier than tailing logs.
