About

Pry JSON Viewer

Features
Read full description

Here's the iOS version: Pry โ€” Native JSON Viewer for iPhone & iPad Pry is a fast, lightweight JSON viewer built natively for iOS. No web views, no compromises โ€” just a native binary that launches instantly and handles your JSON with zero overhead. Paste and Explore Paste any JSON from your clipboard and immediately see it rendered as a collapsible tree. Keys are bold, values are color-coded by type: strings in green, numbers in blue, booleans in orange, and null in gray. Arrays and objects show their item count at a glance. Navigate with Ease Tap any node to expand or collapse it. Pinch-to-zoom and smooth scrolling make it easy to work through deeply nested structures. Nested objects and arrays display with clear indentation and matching closing brackets. Expand all or collapse all with a single tap from the toolbar. Search Across Keys and Values Tap the search icon to instantly filter across all keys and values. Match count updates in real time as you type, and previous/next buttons let you jump between results. Built for Developers Pry shows node count, byte size, and parse time at a glance. Long-press context menus let you copy keys, values, and paths. JSONPath display (e.g. $.data.users[0].name) gives you precise navigation. Long strings are truncated to keep the view clean. Open JSON files directly from the Files app, Safari, or any app that shares .json files. Fast by Design Pry is compiled to a native binary using the Perry framework โ€” TypeScript compiled directly to machine code. It launches instantly, parses JSON in under 1ms, and uses minimal memory. No runtime, no interpreter, no garbage collector.
