Tools that sit on top of the pages you work in.

I build them, check every release and upload it to the stores myself.

03How I build

Nothing ships unchecked.

One script gates every merge and every release, and I do the uploads.

Release checks

release/verify.sh runs before every merge and every release, and the release script stops on a failure.

  • Unit tests
  • Typecheck
  • Browser tests
  • Biome
  • Standards gate

Store reviews

Chrome rejected Takelight 1.0.2 for remote code. The build now strips script CDN addresses and fails if one is left.

  • Chrome
  • Takelight 1.0.2
  • 20 Oct 2026

No tracking

Nothing is gathered from users. The only thing that leaves the browser is the licence key, to check a pass.

  • No account
  • No analytics
  • Licence key only

AI writes, I decide

Agents write and review the code. Deploys, store uploads and secrets stay with me.
