TOOlover is a collection of free, browser-based developer tools built to make everyday development tasks faster — without the noise of ads, paywalls, or sign-up walls.
The story
This started as a personal scratch pad. I kept jumping between random websites to format JSON, diff configs, or convert CSV — each one plastered with ads and cookie banners. So I built my own. Then I kept adding tools. Then I figured I might as well share it.
TOOlover is an indie project — built and maintained by one person. No VC funding, no growth team, no dark patterns. Just tools that work.
How it works
Every tool runs entirely in your browser. Your data never leaves your machine. There is no backend processing your JSON, no server reading your CSV. The page loads, you use the tool, done.
What's available
- JSON tools — formatter, validator, diff, query, schema validator, converters
- Text tools — YAML ↔ JSON, CSV ↔ JSON, and more coming
- Code tools — encoders, decoders, hash generators (in progress)
- Utility tools — QR codes, password generators (in progress)
Free forever?
The core tools are free and will stay free. There's a Pro plan for power users who want extras like history, saved snippets, and API access — but nothing is locked behind a paywall just to be annoying.
