Code Workspace

Features
Read full description

Code Workspace is a free, agent-first development environment for iPad and iPhone. Explore projects, edit and run code, manage Git and connect to remote development tools from one focused workspace. No account, no subscription and no in-app purchases. AN AI AGENT INSIDE YOUR PROJECT Work with a coding agent that understands your project. Mention files with @, use /explain, /fix, /tests and /review, attach screenshots or photos, and follow its progress, even from the Lock Screen with a Live Activity on iPhone. You remain in control. Review sensitive actions before they run, inspect proposed changes line by line and choose the AI provider you want with your own key: Claude, GPT, Gemini and other compatible services. Keys are stored in Keychain. RUN AND FORMAT ON DEVICE Run Python 3.14 and JavaScript files offline with ⌘R and read their output in the terminal. Format JavaScript, TypeScript, JSON, CSS, HTML and Markdown with Prettier, and preview HTML, CSS and JavaScript offline. A WORKSPACE FOR REAL PROJECTS Create a project, clone a repository, or import folders, ZIP archives and files from Files, iCloud Drive or other apps. Edit with Tree-sitter syntax highlighting in 13 themes that can follow Light and Dark mode, split the editor to see two files side by side, and use optional Vim keybindings. BUILT FOR IPAD Use the iPadOS menu bar and keyboard shortcuts, multiple windows, resizable panels, trackpad hover effects, Split View and Stage Manager. GIT, WITHOUT LEAVING YOUR CODE • Review changed files and visual diffs. • Stage, commit, branch, stash, merge, rebase and cherry-pick. • Resolve conflicts visually and see per-line blame. • Draft commit messages with Apple Intelligence (iOS and iPadOS 26 or later). • Connect GitHub, GitLab or your own Git server, and review pull and merge requests. SSH, SFTP AND A PERSISTENT TERMINAL Use interactive terminal sessions for shells, REPLs, Vim and long-running processes. Create SSH profiles, authenticate with passwords or Ed25519/RSA keys and access remote files through SFTP. PROFESSIONAL LANGUAGE TOOLING Connect language servers on your development host for completion, diagnostics, definitions, references, code actions and rename. Debug with DAP breakpoints, stepping, call stacks and variables. Works with Swift, JavaScript, TypeScript, Python, Dart, Go, Rust, HTML, CSS and Markdown. BUILT FOR IPHONE DUO Unfold iPhone Duo for the full multi-panel workspace on the inner display; fold it to keep working in the compact one-handed layout. LOCAL FIRST, CONNECTED WHEN YOU CHOOSE Files stay on your device unless you choose a Git remote, SSH server, AI provider or iCloud backup. By DVX Labs

About

JSON Master

Features
Read full description

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.
