JSON Master vs Herdwick

JSON Master is a native JSON editor built around what you actually do with JSON every day: find the value, copy its path, understand what a field really contains — and fix the file when it doesn't parse. See the whole document as a tree and as colour-highlighted source, side by side on iPad and Mac. Both are the same file: change one, and the other follows. FIND YOUR WAY • Command palette: type a few letters and jump to any node or run any command — "custcity" finds customer.address.city • Breadcrumbs, back and forward after every jump • Search keys and values, step through matches • Full keyboard navigation on Mac and iPad UNDERSTAND A VALUE • Unix timestamps shown as readable dates • JWT tokens decoded: header, claims and expiry • base64, ISO dates and URLs recognised on sight • Warnings for integers too large for JavaScript • Collapsed branches show their first keys, so you often don't need to open them QUERY, COMPARE, GENERATE • JSONPath queries with live results — tap one to jump to it • Compare two documents by structure, not by line breaks • Generate Swift Codable, TypeScript interfaces or JSON Schema • Summary with node counts, depth and findings worth a look FIX AND EDIT • A broken file shows the exact line and column of the error • One-tap repair for almost-JSON: comments, trailing commas, single quotes, bare keys • Edit keys and values, change types, add, duplicate and delete — every edit undoable • Format, minify, sort keys, expand embedded JSON strings, convert JSON Lines • Copy paths in six notations: dot, JSONPath, brackets, jq, Swift and JSON Pointer MADE FOR LARGE FILES Files of tens of megabytes open without freezing, with progress shown while they load. YOUR WAY Four themes — Midnight, Graphite, Amber CRT and Daylight — and seven languages: English, German, French, Ukrainian, Spanish, Japanese and Portuguese. No account, no ads, no tracking. Your files stay on your device.

Answer your coding agents from your phone. Herdwick connects to herdr on your own Mac or Linux machines over SSH. See what your agents did and reply from iPhone or iPad. ONE INBOX Every agent on your saved hosts, in one list. The ones waiting on you come first. READ THE CONVERSATION Conversations from omp, Claude Code and Codex show as a chat. Tool steps fold into one line; open it for detail. Edits show as diffs, line by line. Other agents, and transcripts that aren't available, open in the terminal. A line marks what's new since you last looked. ANSWER Tap an option on a supported question or permission prompt, or type a reply. The terminal is always there. USE THE TERMINAL Live output, a message box and keys for Esc, Tab, arrows, Enter and Ctrl-C. Typing mode is optional; it takes control and resizes the pane on your host. CONNECT YOUR MACHINES Use SSH with a key made on your device, or a password. Tailscale sign-in and a machine picker are built in; Tailscale SSH needs setup on your host and tailnet. Nothing to install for Herdwick on your host beyond herdr. KEEP YOUR PLACE While Herdwick reconnects, your last view stays on screen. Pick from seven terminal themes, set separately for light and dark. TRY THE DEMO Look around a scripted demo host before you connect your own. No Herdwick account needed. PRIVACY Your SSH private key stays in the device Keychain. Messages and attachments go to your host, not to a Herdwick server. No analytics. If you use Tailscale, its privacy policy applies. REQUIREMENTS iOS 26 or later, and a Mac or Linux host running herdr that you can reach. Your agents run on the host, not on your phone. Herdwick is independent and is not affiliated with or endorsed by the herdr project or Tailscale Inc. Tailscale is a registered trademark of Tailscale Inc.
