About DevTK
DevTK is a collection of free, fast, and privacy-first developer tools. Every tool runs entirely in your browser — we never upload, store, or transmit your data.
Privacy First
Every tool on DevTK runs 100% in your browser. We never upload, store, or transmit any of your data to any server. Your JSON, tokens, passwords, and code stay on your machine.
Free & Open
All core tools are free forever. No account required, no usage limits. Premium features are optional and exist to support continued development.
Built for Developers
Designed with a dark-first UI, keyboard shortcuts, and workflows that developers love. Supports both English and Chinese.
