A simple standard

Useful first.
Quiet by default.

01

One clear purpose

No feature piles. Every tool starts with a specific problem and stays focused.

Privacy without ceremony

No account or tracking unless a feature genuinely cannot work without it.

03

Built in the open

Source code, issues, changes, and known limitations are visible on GitHub.

User-supported work

Help small tools stay useful.
