TOOLS / LOCAL-FIRST

Diagnose. Document. Decide.

Tools for turning a frustrating browser problem into a short series of observable tests—without a login or remote scan.

Why small experiments work better

Browser problems have multiple plausible causes. Changing cookies, extensions, network settings, and browser preferences simultaneously may hide which factor mattered. A simple investigation starts with scope: is the failure one website, one profile, all websites, or the entire device? The tools are intended to organize those observations, not make invisible scans of your computer.

We do not connect to your browser’s private history, access your accounts, or run remote tests. You supply the symptoms. The suggestions are educational; follow your browser publisher’s official help when a setting or menu changes.

Privacy-first design
