About Praticulus
Fast, free, privacy-first tools for developers and everyone.
Why Praticulus?
We got tired of bloated tools with popups, mandatory signups, and trackers everywhere. Praticulus is different:
- 100% client-side: Your data never leaves your browser. Verifiable in DevTools → Network
- No signup: Every tool works immediately, no account needed
- No tracking: No cookies, no analytics pixels, no fingerprinting
- Fast: Lightweight pages, no heavy frameworks. Lighthouse 100 budget held on every tool
- Free: All tools are free to use, forever
Read the full privacy policy for the technical details and how to verify the claims yourself.
