About

What's Kernel?

Kernel provides sandboxed, ready-to-use Chrome browsers for browser automations and web agents. This repo powers our hosted services.

Key Features

Sandboxed Chrome browser that Chrome DevTools-based browser frameworks (Playwright, Puppeteer) can connect to
Remote GUI access (live view streaming) for visual monitoring and remote control
Configurable live view settings (read-only view, browser window dimensions)
Controllable video replays of the browser's session

What You Can Do With It

Run automated browser-based workflows
Develop and test AI agents that use browsers
Build custom tools that require controlled browser environments

Implementation

This image can be used to run headful Chromium in a Docker container or with Unikraft unikernels. The unikernel implementation builds on top of the base Docker image and has the additional benefits of running on a unikernel:

Automated standby / "sleep mode" when there is no network activity (consuming negligible resources when it does)
When it goes into standby mode, the unikernel’s state gets snapshotted and can be restored exactly as it was when it went to sleep. This could be useful if you want to reuse a session’s state (browser auth cookies, interact with local files, browser settings, even the exact page and window zoom you were on).
Extremely fast cold restarts (`

export UKC_TOKEN=

3. Build the image

IMAGE=YOUR_UKC_USERNAME/chromium-headless-test:latest images/chromium-headless/build-unikernel.sh

4. Run it

IMAGE=YOUR_UKC_USERNAME/chromium-headless-test:latest images/chromium-headless/run-unikernel.sh or IMAGE=YOUR_UKC_USERNAME/chromium-headful-test:latest VOLIMPORT_PREFIX=official images/chromium-headful/run-unikernel.sh

When the deployment finishes successfully, the Kraft CLI will print out something like this:

Unikernel Notes

Don't lose this

Three weeks from now, you'll want Kernel Images again. Will you remember where to find it?

Save it to your library and the next time you need Kernel Images, it’s one tap away — from any AI app you use. Group it into a bench with the rest of the team for that kind of task and you can pull the whole stack at once.

⚡ Pro tip for geeks: add a-gnt 🤵🏻‍♂️ as a custom connector in Claude or a custom GPT in ChatGPT — one click and your library is right there in the chat. Or, if you’re in an editor, install the a-gnt MCP server and say “use my [bench name]” in Claude Code, Cursor, VS Code, or Windsurf.
