I build tiny, focused utilities for the parts of the workflow that quietly waste your attention — and every so often I measure what they are actually worth. All free, all open source, all honest about what they don't know.
Each tool has its own site with screenshots, install steps and full documentation. One entry here is a report rather than a download.
No dashboards, no accounts, no background services you didn't ask for. A tool should do the one thing its name promises.
Nothing is collected or phoned home. What runs locally stays local — the only network call is the one you configure yourself.
Source, issues, and releases are all on GitHub under permissive licenses. Read it, fork it, ship your own version.
