Kernel

Kernel is browser infrastructure for AI agents and automations. It runs sandboxed cloud Chromium browsers that spin up in under 30ms, with Playwright execution, computer-use controls, managed authentication into third-party sites, reusable browser profiles, proxies, pre-warmed browser pools, session replays, live telemetry, and a serverless App platform for deploying and invoking agent actions. Kernel exposes a REST API (OpenAPI 3.1, 135 operations across 22 tags), first-party TypeScript, Python and Go SDKs, a CLI, and a centrally hosted MCP server so agents can drive real browsers. Backed by General Catalyst.

Kernel publishes 22 APIs on the APIs.io network, including API Keys API, Apps API, Audit Logs API, and 19 more. Tagged areas include Company, Browser Automation, Web Agents, Browser Infrastructure, and AI Agents.

Kernel’s developer surface includes authentication, CLI, changelog, documentation, API reference, getting-started guide, support, and 25 more developer resources.
