About Developer Utility

What is Developer Utility?

Developer Utility is a collection of fast, simple and privacy-friendly online tools built for developers. Whether you need to format JSON, decode a JWT, generate UUIDs, or convert timestamps — everything works right in your browser with no data sent to any server.

Our Principles

• Client-side First: Every tool runs entirely in your browser. No server round-trips.
• Privacy First: Your data stays on your device. We never see, store, or transmit your input.
• No Account Required: Just open and use. No sign-up, no login, no friction.
• Fast by Design: Tools are lightweight and load instantly.
• Developer Workflow: Tools are organized by workflow, not by alphabet.

Technology
