▌
Kernel CLI · kernel bundle
Use the Kernel CLI to manage cloud browsers, apps, profiles, proxies, managed auth, API keys, projects, and organization limits. Use when installing or authenticating the CLI, looking up current command syntax, or choosing the right command group.

Kernel Auth · kernel bundle
Use Kernel managed auth after choosing a browser path that genuinely requires an authenticated website UI or authenticated browser behavior. Prefer a dedicated API, CLI, MCP server, or authoritative local records for operations they support; a URL alone does not require browser auth. Reuse or create auth connections, complete hosted login without abandoning the task, launch profile-backed browsers with telemetry, and handle reauthentication safely.

Generate Video · kernel
Generate crisp, perfectly smooth MP4 videos from a web page or animated visualization by driving headless Chromium over the Chrome DevTools Protocol (CDP) with deterministic frame-stepping, then encoding with ffmpeg and (if remote) sharing via a cloudflared tunnel. Use when asked to make/generate a demo video, explainer clip, launch/marketing animation, social teaser, or any short rendered video from a web scene — especially animated stat/timeline/diagram visualizations — and when you need to iterate on it (tweak, re-render, compare). Solves the common "the recording has hitches / judder / dropped frames" problem.

Kernel Agent Browser · kernel bundle
Best practices for using agent-browser with Kernel cloud browsers. Use when automating websites with agent-browser -p kernel, tuning stealth or proxy behavior, persisting profiles, handling iframes, discovering Kernel session IDs or live views, or cleaning up cloud sessions.

▌
Debug Browser Session · kernel
Systematically debug a Kernel cloud browser session — VM issues, network errors, Chrome crashes, page-load failures, and live-view problems. Use when a browser session misbehaves (e.g. ERR_HTTP2_PROTOCOL_ERROR, "browser not responding", blank/error pages, captcha or "checking your browser" blocks, live view not loading) and you have the session ID. Drives the Kernel CLI to inspect session status, screenshots, page state, VM logs, network connectivity, and telemetry events (which remain readable even after the session is deleted).

▌
Diff Profile Archives · kernel
Compare two Kernel profile snapshots to investigate behavioral differences. Use when an issue (e.g. login failure, captcha, broken automation, vendor mismatch) reproduces on one profile but not another, or when a "good" vs "bad" profile needs to be diffed. Takes two profile IDs/names plus an issue description, downloads and extracts both profiles via the Kernel CLI, and surfaces differences in cookies, storage, preferences, extensions, and login state that could explain the issue.

▌
Kernel Browser Harness · kernel
Best practices for using browser-use's open-source browser-harness with Kernel cloud browsers over CDP. Use when driving a Kernel browser from browser-harness, extracting a CDP URL from `kernel browsers create`, or running multi-step or parallel harness sessions against Kernel.

▌
Kernel Typescript Sdk · kernel bundle
Build Kernel browser automation in TypeScript with server-side Playwright or CDP, including profiles, proxies, and reliable session cleanup.

▌
Profile Website Bot Detection · kernel bundle
Profile a website for bot detection vendors using stealth vs non-stealth Kernel browsers. Use when analyzing bot detection on a website, comparing stealth effectiveness, identifying anti-bot vendors and products, or detecting challenge types.
