I Built 750+ Free Developer Tools Using Pure Frontend

No servers. No databases. No backend code. Just HTML, CSS, and JavaScript — 750+ tools, all running in your browser. Every single one is free, no signup required.

The "Why"

I kept bookmarking the same online tools: JSON formatters, regex testers, UUID generators, hashing tools. Each one was on a different site, each with different ads, different layouts, different limitations.

So I built my own collection. And then I kept adding to it.
