About

SafeJSON is an all-in-one local JSON toolkit built exclusively for developers. All parsing, comparison, JWT decoding and validation runs 100% inside your browser, with zero user data uploaded to external servers. Core features include standard JSON formatter, visual JSON Diff, JWT token decoder, JSONPath query engine, and JSON Schema validator. It supports huge 50MB+ JSON files powered by Web Workers, dark mode, collapsible tree views, and one-click raw JSON export. Users can independently verify full privacy via Chrome DevTools Network panel — no API keys, tokens or confidential payloads leave your device. The core toolset is permanently free, with advanced features (Diff & JWT) available via SafeJSON Pro ($5/month or $39/year). The full codebase is fully open-source on GitHub for full audit.

About

Eclipse Theia is an extensible platform to develop multi-language Cloud & Desktop IDEs with state-of-the-art web technologies. Not sure whether you need a web or desktop version or both? With Theia you can develop one IDE and run it in browsers or native desktop application from a single source. The Theia project is hosted at the Eclipse Foundation, a not-for-profit corporation, and is developed by a diverse community. Unlike other "open-source" projects, projects hosted at an Open-Source Foundation are protected against single-vendor decisions against the interest of the diverse community. Theia is designed in a modular way to allow extenders and adopters customizing and extending every aspect of it. Composing a custom IDE-like product is as easy as listing all needed extensions in a package.json file. Adding new functionality by implementing your own extensions is easy, too and provides all the flexibility you need.
