What We Built
Every developer has the same frustration: you're mid-debug, you need to quickly format JSON or decode a JWT, and you end up in three different browser tabs, each with ads and a "please subscribe" modal. We built Utilio to fix that.

Our Principles
Privacy First
Every tool that can run locally, does. JSON formatters, converters, generators — none of them upload your data anywhere.
Fast by Design
No waiting for servers. Browser-native APIs and WebAssembly mean most tools respond in milliseconds.
Built for Builders
Every tool we add solves a real problem we hit ourselves. If it feels like busywork to use, we redesign it.
Always Accessible
No paywall for core functionality. The tools that drive the most daily value are and will remain free.
REST API for Developers
Every generator on Utilio — passwords, UUIDs, QR codes, hashes, Lorem Ipsum, URL shortener — is available via a simple REST API. Integrate directly into your apps, scripts and CI pipelines. API Basic starts at $2/month for 2,000 requests/day.

Also known online as Inzi · Software Development Executive · Pakistan
Utilio (also called Inzi Tools, Inzimam Tools or Shafy Dev Tools by friends) started as a personal toolkit I kept bookmarking across different websites. I rebuilt everything in one place that runs privately in your browser. If you found this through a search for "inzimam tariq tools" or "shafy tools" — welcome!
