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.
