Urbi Tools is a growing collection of free, browser-based utilities built for developers, designers, and anyone who works with data, text, and code. Every tool runs entirely in your browser — no accounts, no servers, no tracking, no data ever leaves your device.

Urbi Tools is organized into three categories:
Text Tools

Why Privacy-First Tools?
Most online tools send your data to a server to process it. That means your code snippets, JSON payloads, API keys accidentally left in data, and personal text all travel to a third-party server, get logged, and potentially stored.
Every Urbi Tool processes data locally using browser APIs — the JavaScript runs on your machine, and nothing is transmitted. This makes them safe to use with sensitive data and usable offline once the page loads.
What’s Coming Next?
New tools are added regularly. The roadmap includes tools for color conversion, regex testing, hash generation (MD5, SHA), diff comparison, CSV to JSON conversion, and more developer utilities. Subscribe to the newsletter at the bottom of any tool page to get notified when new tools ship.
