JSON Master

Features
Read full description

JSON Master is a fast, native JSON editor for iPhone, iPad and Mac, built around what you do with JSON all day: find a value, copy its path, copy a branch, and understand what a field really contains. The document is shown two ways — as a tree and as highlighted source — and both are the same file. The tree is for reading and restructuring, the source for fixing what does not parse. FIND YOUR WAY • Command palette (⌘K): every command by name and a fuzzy jump to any node • Breadcrumbs, plus back and forward after every jump • Search over keys and values; matching branches open by themselves • Full keyboard control on Mac and iPad READ • A tree with type badges, item counts, indent guides and previews of collapsed objects • Highlighted source that keeps working even when the file does not parse • A broken file explains itself: the exact line and column, one tap away • One-tap repair for almost-JSON: comments, trailing commas, single quotes • Large files open in the background without freezing COPY • Paths in six notations: dot, JSONPath, brackets, jq, Swift and JSON Pointer • Values, whole branches (formatted or minified), keys and key-value pairs UNDERSTAND The inspector recognises Unix timestamps, JWT tokens, base64, ISO 8601 dates, URLs and integers too large for JavaScript — and shows what they mean. TOOLS • Format, minify, sort keys, unwrap JSON embedded in strings • Export as JSON or minified JSON JSON MASTER PRO One in-app purchase, no subscription, for iPhone, iPad and Mac: • JSONPath queries with results as you type • Structural compare: reordered keys and reindentation are not differences • Generate Swift Codable, TypeScript interfaces or JSON Schema • A summary that flags duplicate keys, unsafe integers and JSON hidden in strings • Export as CSV • Graphite and Amber CRT themes EVERYWHERE • Tree and source side by side on Mac and iPad • Midnight and Daylight themes, plus Graphite and Amber CRT with Pro • Seven languages: English, German, French, Ukrainian, Spanish, Japanese and Portuguese. The app follows your system language or the one you choose for it No account, no ads, no tracking.

SkillPilot is a discovery and monitoring client for open-source AI developer tools: agents, Claude skills, MCP servers, CLIs and repositories. It shows you what exists, what changed, and what needs attention, and it links every entry back to its source on GitHub. Find the right tool Browse a catalog organised into 12 categories, from Development, AI Agents and Automation to Marketing, Design, Security, Data and Research, RAG and Knowledge, LLM Ops and Token and Cost Optimization. Search by name or description, open a category to see its subcategory shelves, and tap any card for the owner, type, description, tags, a short README excerpt quoted from the project, and a direct link to the repository. See what is new The New tab surfaces a Daily Winner, the latest releases and the tools that are rising fastest this week, so you can check the ecosystem in a minute. Keep your stack healthy The Browse tab gives your monitored tools a single health score with tiles for updates, breaking changes and security issues, plus a list of priority alerts. My Skills lists every tool you track with its status, installed and latest version and an authority score out of 100. Open a tool to read its health summary and security posture, what changed between versions, a side by side version comparison and a recommended action. Act on alerts The Alerts inbox groups open alerts by severity (Critical, High, Medium, Low), names the alert type, and links to the evidence on GitHub. Mark an alert resolved or start a migration review from the same screen. Read-only by design SkillPilot never installs, runs or changes anything on your machine. It reads public data about open-source projects and presents it; every decision stays with you.
