About DevCraft
Engineering a faster, safer, and truly private developer utility suite.
Our Mission
Modern software engineers frequently work with confidential credentials, proprietary JSON schemas, relational database queries, and private architecture diagrams. Unfortunately, most popular web-based converters and diff tools send your data to remote backend servers, exposing sensitive intellectual property to network inspection and third-party logging.
DevCraft (devcraft.run) was founded on a simple principle: Developer tools should execute entirely inside your computer’s RAM.
The In-Memory Architecture
Every single utility on DevCraft (whether it is a 10-megabyte JSON diff calculation, an interactive Mermaid 11 architecture diagram render, a JWT claim evaluation, or an automated SQL query formatter) runs 100% in client-side Web Workers and JavaScript engines. No data ever leaves your device.
Open Source & Air-Gapped Verification
We believe trust is earned through transparency. DevCraft contains no tracking cookies, no Google Analytics tracking pixels, and no backend API proxies. You can disconnect your Wi-Fi or turn on Airplane Mode, and DevCraft will continue working without interruption.
