KERNEL is browser infrastructure for AI agents. Its features cover five jobs: running browsers, accessing any website, carrying state, logins, and payments into a session, controlling the browser, and seeing what happened afterward.

Run browsers

Browsers

Headful by default, with headless and GPU-accelerated options.

Browser Pools

Pre-configured browsers kept ready, so acquiring one skips start-up latency and the browser create rate limit.

Code Execution Platform

Deploy your agent next to its browser and invoke it on demand or on a schedule.

Access any website

Stealth

Custom fingerprints and anti-bot detection defaults run on every browser, plus a managed CAPTCHA solver.

Proxies

Datacenter, ISP, residential, mobile, or bring-your-own.

Config Registry

Give it a URL and get browser and proxy settings that have worked on that site.

Carry state, logins, and payments

Profiles

Persisted browser state (cookies, storage, logins, history, open tabs) that you can load into any browser.

Vaults

Store credentials and fill them safely in a website form, with provider integrations like 1Password.

Authentication

Fill logins from a vault, or let managed auth log in and attempt to reauthenticate eligible connections.

Payments

Let agents complete checkouts through wallet integrations like Link by Stripe, without card numbers passing through your app or model.

Control the browser VM

Playwright Execution

Run Playwright code inside the browser’s VM and get the result back in one call.

Computer Controls

OS-level mouse, keyboard, and screenshots that match what computer use models emit.

WebMCP

Call the structured tools a website exposes instead of guessing which controls to click.

Browser REPL

A persistent JavaScript runtime next to the browser, so an agent can build on its own helpers across calls.

See what happened

Live View and Replays

Watch or take over a running session, and record any session as an MP4.

Browser Telemetry

Structured events for navigation, network, CDP, captcha, and proxy activity.

Audit Logs

A record of API requests across your organization, searchable and exportable on Start-Up and Enterprise.
