DevUtils is a professional suite of free, zero-latency utilities that run entirely in your browser using WebAssembly. Unlike traditional tools, it guarantees maximum privacy by ensuring data—such as JWTs, SQL, and JSON—never leaves your device. The toolkit features specialized categories for DevOps (Docker to Compose, Nginx Config), Data Engineering (JSON to Schema, Mass Relational Mock Data), and Web Development (Socket Client, Curl to Code). Installable as a PWA, it works offline without internet and handles massive files bounded only by your RAM.
