Our Mission
We believe developer tools should be fast, free, and private. Too many online tools send your code to their servers, wrap features behind paywalls, or bombard you with pop-ups before you can even paste your JSON.
DevUtility Hub is different. Every single tool runs 100% in your browser. Your data never touches a server. No accounts, no limits, no tracking. Just tools that work.
By the Numbers
What Makes Us Different
Privacy by Architecture
Not just a promise — our tools literally cannot access a server because there isn't one. All processing is JavaScript running on your machine.
Tool Pipeline (Exclusive)
Chain multiple tools together into a processing pipeline. Decode Base64 → Format JSON → Extract Path — all in one flow. No other dev tools site offers this.
Smart Paste Detection
Paste any content anywhere and our detector automatically identifies the format (JSON, JWT, UUID, Base64, XML, SQL, cron, CSV) and routes you to the right tool.
Transparent Privacy Dashboard
Every tool page shows a real-time privacy audit — exactly what permissions are used, what data is stored, and what network requests are made (none).
Keyboard-First Design
Ctrl+K to search, ? for shortcuts, H for home. Designed for developers who live in their keyboards.
Hardened Security
15+ HTTP security headers including CSP, HSTS with preload, X-Frame-Options DENY, and a strict Permissions-Policy. No source maps in production.
