JSON Brace turns unreadable JSON responses into beautifully formatted, navigable data structures right in Safari.

What it does:

Smart JSON Detection
Automatically finds and formats JSON content on any webpage. No manual activation needed - just visit a page with JSON data and see the difference immediately.

Advanced Navigation
Click to collapse or expand any object or array. Set your preferred expansion depth (1-10 levels) to see exactly the detail you need.
Preview collapsed content at a glance or disable previews if you prefer a cleaner view.

Lightning-Fast Search
Find any key or value instantly. Results highlight as you type, with arrow navigation between matches.
Use Enter or Esc+Enter to jump results while your cursor is in the search bar - perfect for debugging API responses or exploring large datasets.

Keyboard Power User Features

Cmd+Shift+U expands everything at once

Theme Intelligence
Choose between a crisp light theme for clear visibility during daytime work and a soothing dark theme for reduced eye strain at night. Switch whenever you need - both options are designed for maximum readability and user comfort, day or night.

Developer Productivity Tools
Copy any value with a single click. Toggle between the original raw JSON and the formatted view instantly.

Privacy by Design
Everything happens on your device. Your JSON data never touches external servers. No accounts, no tracking, no data collection of any kind.

Who uses JSON Brace:
Frontend developers debugging API calls. Backend engineers testing endpoints. Data scientists exploring API responses. DevOps teams analyzing configuration files. Anyone who's tired of squinting at minified JSON.

Works with Safari 15.0 and later on iPhone, iPad, Mac, and Apple Vision Pro.
