Kernel
A developer portfolio that builds a site as you scroll.
A desk from night to morning on the home page while a project is built on its monitor as you scroll, case studies with before-and-after numbers, services with prices, a career as a git log, writing, an about page with Uses and a contact page with an intro call and a paid code review. Lighthouse 100 out of the box.

AI ready · MCP
Your AI agent knows Kernel
AGENTS.md, CLAUDE.md and Cursor rules explain how the site is built. The WPTom MCP server goes further: Cursor, Claude Code, VS Code, PhpStorm and the other JetBrains IDEs, Codex or OpenCode look up what they need instead of guessing, so their edits fit the first time.
- Every componentprops and docs of all 35, from your project
- Your versionwhich template, version and variant, and when an update is out
- The docssearches docs.wptom.com while it works
$ npx -y wptom mcpContent where you want it
Legal pages, posts, projects and services and every text are typed content, edited in Keystatic, Sanity or EmDash. Pick EmDash with --cms emdash.
Updates keep your edits
npx wptom update merges each new version around your changes, line by line, and marks the rare conflict.
Real photos included
19 photos made for Kernel, yours to use on every site you build with it. Swap them for your own whenever you like.
Ready for more languages
Ships in English. Add a language in one file and translate the content: Kernel adds the language switcher, hreflang links and a sitemap per language, and Keystatic, Sanity and EmDash follow.
Search built in
Press ⌘K and search every page, posts, projects and services included, with no service to set up. Switch to Algolia when you outgrow it.
Make it yours in minutes.
One file holds your brand: three colors, fonts, corners. Every shade for both themes comes from it, and the build stops if a color would be hard to read.
Try accents in the preview above, or live in the demo (opens in a new tab).

Questions
Can I see it before buying?
Yes. The live demo is the template itself with its demo content: every page, the search and the 404 game. Features that need your own keys (AI chat, analytics, booking, media, email, payments, sign-ups) show how to turn them on.
Which CMS can I use?
Out of the box, content is Markdown and JSON in your project, edited in Keystatic. Switch to Sanity with one setting, or create the site with EmDash running inside it. The docs walk through each.
Where can I host it?
It is set up for Vercel, the EmDash version for Cloudflare. Pages are static, so other hosts work with their Astro adapter.
Do I need to know Astro?
Basic HTML and CSS are enough for text, colors and images. The docs and the AGENTS.md file cover the rest, for you and your AI agent.
How do updates work?
Run npx wptom update. It merges the new version around your edits.
Can I use it for a client?
Yes, for as many clients as you like: every paid license includes client projects.
Can my site be in another language?
Yes. It ships in English; add a language in src/i18n/locales.json and translate the content. The language switcher, hreflang links and sitemap follow, in every CMS.
