About
DevToys is a free, open-source, cross-platform desktop application for Windows, macOS, and Linux that provides over 30 built-in developer utilities. It covers tasks like JSON formatting, Base64 encoding, JWT decoding, text comparison, hash generation, and more — all offline and privacy-focused. The app is extensible via an SDK, supports a CLI mode for CI pipelines, and features smart clipboard detection to suggest relevant tools automatically.
Problem
Developers frequently need simple utilities like JSON formatters, encoders, or text comparers but must rely on untrustworthy online websites that may expose their data.

How it works
