A few months back I posted here about building FreeToolHub, a set of free browser tools because I was tired of sites that make you sign up just to format a JSON file.
Since then it grew a lot. What started as 81 tools is now 114. I added a whole cluster of chemistry and math calculators (equation balancer, molecular weight, periodic table, trig, stats) after noticing students were the ones actually using the site the most.
Everything still runs the same way. No login. No server. Your data never leaves the browser. If your internet dies mid task, the tool still works because it already loaded everything it needs.
The bigger update: I made the whole codebase public. Anyone can look at how it works, fork it, or use it for their own project.
Repo: github.com/HARISHCEXPERT/freetoolhub
Live site: freetoolhub.app
Still a solo project. No team, no funding, just me building this around a full time job. If you find a bug or want a tool added, open an issue on the repo, I actually read them.
