About devtoolkit.fyi

Our Mission

devtoolkit.fyi was created to provide developers with fast, reliable, and privacy-respecting utilities for everyday tasks. We believe that simple tools shouldn't require you to compromise your privacy or wade through ads and tracking scripts.

Privacy First

Every tool on this site runs entirely in your browser. We don't have a backend server processing your data. We don't track you. We don't collect analytics beyond basic pageview counts. Your data never leaves your device.

Why Client-Side Processing?

• Security: Your sensitive data stays on your device
• Speed: No network round-trips means instant results
• Privacy: We can't see your data because we never receive it
• Reliability: Works offline once the page is loaded

Our Principles

1. Simple and Fast: Each tool should do one thing well, with minimal loading time
2. Privacy-Respecting: No tracking, no cookies, no data collection
3. Accessible: Works on all modern browsers and devices
4. Free Forever: Core tools will always be free with no paywalls
5. Open and Transparent: Built with standard web technologies

Technology Stack

devtoolkit.fyi is built with:

• Astro: Fast, modern static site generator
• React: For interactive tool components
• Tailwind CSS: Responsive, accessible styling
• TypeScript: Type-safe, maintainable code
• Web APIs: Native browser APIs (crypto, clipboard, etc.)

Future Plans

We're constantly adding new tools based on developer feedback. Upcoming additions include:

• Regex tester with visual highlighting
• Timestamp converter
• Diff checker for text and code
• JWT decoder and validator
• Color converter (HEX, RGB, HSL)
• And many more...

Feedback & Suggestions

Have a tool request or found a bug? We'd love to hear from you. This project is built for developers, by developers, and your feedback helps us prioritize what to build next.

Open Source

We believe in transparency. Many of our individual tools and utilities will be open-sourced for the community to use, learn from, and contribute to.
