New open-source developer tools, the day they appear.
Most tools worth adopting surface in the noise before anyone writes about them. GH Radar sweeps newly created repositories every day and keeps the ones that look like real developer tooling, so you can filter the flood down to the handful actually worth a look.

Zero-dependency CLI expense splitter — computes minimal settlement transactions
Every repo carries a potential score combining log-scaled stars and forks, recent commit activity, project health, and how deeply it matched the developer-tool topics the collector watches. Stars and forks are log-scaled so a single outlier cannot flatten everything below it, and forks carry their own weight, so a young project people are already building on can outrank a more starred one nobody has adopted.
Age is deliberately excluded. Every repo in the collection is currently the same age, so a growth rate would carry no information and would just rank by raw stars. The weighting is worth revisiting once the collector has covered enough days for velocity to mean something.

I build tools that make other people's work faster, and I ship them in public while I do it.
Most of them started as friction of my own: a component library I needed twice, an automation I was tired of running by hand. They turned out to be useful to people I'll never meet. GH Radar is the same bet. I wanted a way to find what was worth adopting before the noise buried it, so I built one and left it here for anyone else doing the same hunt.
The goal isn't a list of repos. It's a body of open, dependable tools that other developers reach for without thinking twice.
