Our Philosophy
Every tool is open source. Read the code, review the manifest, and understand what it does before loading it in developer mode.
No accounts, no servers, no external APIs. Settings and data stay in your browser's local storage and never leave your machine.
Each extension is built to do one thing well with minimal permissions. No background analytics, no telemetry, no ads.
Published under GPLv3. Fork it, audit it, improve it, or contribute a new source. Open by default.
