Simple, privacy-first pricing
Core JSON formatting is free forever. Advanced tools for developers who debug JSON every day.
You paste sensitive data into online tools every day. Here's why that matters.
jsonformatter.org leaked 80K credentials in November 2025, including AWS keys, GitHub tokens, database passwords, and banking details.
The JSON Formatter extension was sold, closed-sourced, and turned into adware after reaching 2M users.
Every time you paste an API response, a JWT token, or a config file into a server-side tool, your data makes a round trip through infrastructure you do not control.
SafeJSON Pro gives you Diff, JWT, JSONPath, and Schema - all 100% client-side. Your data never leaves your browser. Prove it: open DevTools while using any Pro tool.
