Jayson

Native macOS JSON Viewer

A dedicated desktop surface for the JSON you actually touch — API dumps, config blobs, clipboard chaos. Local-first, keyboard-first, Raycast-ready.

What It Does

Most JSON tools are a throwaway website or a buried IDE panel. Jayson is the native macOS cockpit: paste or open a file, query it, diff it, and ship it without leaving the keyboard.

Command palette (⌘K) for files, tabs, tools, and transformers.
jq-lite queries and a path bar, without leaving the app.
Deferred parse and worker offload, so large JSON stays snappy.
History, diff, split view, and a Raycast inbox for snippets from anywhere.
