What Makes This Different
100% Private by Default
Every tool runs entirely in your browser. Nothing you type, paste, or upload ever leaves your device or reaches a server. No logs, no uploads, ever.
Instant Results
All processing happens client-side in real time. There are no network round-trips, no waiting for a response, and no rate limits.
Always Free
No account, no subscription, no paywalls. Every tool is free to use as many times as you like.
No Tracking of Usage
We don't track what you paste into tools. Analytics (if enabled) only measure page views and are fully anonymised.
Developer-First Design
Keyboard-friendly, dark-mode supported, fast-loading, and built to handle real-world inputs like minified JSON, multi-line code, and large datasets.
Works Offline
Once the page has loaded, most tools work without an active internet connection. Ideal for use in restricted or low-connectivity environments.
