Philosophy

I'm a solo builder. Every extension I install is a trust decision. The Chrome Web Store is full of closed-source extensions with broad permissions and no way to verify what they actually do.

So I build my own.

Minimal Permissions No broad "all websites" access. Each extension asks for exactly what it needs.
Zero Network Calls No analytics, no tracking, no telemetry. Everything runs locally.
Inspectable in Minutes Small codebases, plain JavaScript, no bundlers. Read every line.
CWS Ready on Day One Manifest V3, no obfuscation, no remote code. Ships immediately.
