About DevUtils
Free, fast, and privacy-friendly developer tools — no signup required.
DevUtils is a growing collection of 20 online utilities for developers: formatters, encoders, generators, converters, and network tools. It was built to be the opposite of the cluttered, ad-heavy tool sites we were tired of using — clean, fast, and respectful of your privacy.
Why DevUtils?
Privacy-friendly
Almost every tool runs entirely in your browser. Your input never touches our servers.
Fast & free
No signup, no paywalls, no clutter. Just open a tool and get your result instantly.
Built for developers
A focused set of utilities for the tasks developers reach for every day.
Clean by design
A calm, distraction-free interface that respects your time and attention.
How it works
Wherever possible, tools are implemented with standard browser APIs and run completely on your device. That means the data you paste in stays with you. A few network tools (such as DNS Lookup and My IP) necessarily query external services to do their job — we explain exactly which ones in our Privacy Policy.
