JS Shell vs HTTP Request

JS Shell is a pocket-sized developer console that lets you write, run, and test web code (HTML, CSS, JavaScript) directly on iOS and macOS. No Xcode, no laptop, no remote server. Paste a page in, tap run, and it loads in a real WKWebView served from a local HTTP origin. A real secure-context origin on iOS, so modern web APIs — from WebRTC to Geolocation — behave the way they should. KEY FEATURES Local HTTP server. An in-process server bound to the loopback interface. Provides a real secure-context origin so modern Web APIs work out of the box. Not reachable from outside the device. JavaScript REPL. A full JavaScript runtime backed by JavaScriptCore. Type js to enter the REPL. console.log, fetch, setTimeout, setInterval, Promises, and async await are all available. Real Promises, real microtasks, real JSON parsing, real URL parsing. Geolocation support. Test navigator.geolocation on a real iOS device. Permissions are handled by the system, just like Safari. Useful for validating location-based web features without deploying to a server. Persistent file system. Files you paste live in your Documents directory and survive app restarts. Each downloaded package gets its own directory. iCloud backup picks them up like any other app data. SQLite key-value store. A real B-tree on disk via SQLite. Read and write from your pages with same-origin fetch. No CORS configuration required. curl. A subset of curl built on URLSession. The flags X, H, d, i, I, o, A, m, v are supported. Pretty-prints JSON responses and saves binary blobs to the virtual filesystem. Archive extraction. In-process tar, tar.gz, tgz, gz, and zip extraction. No shelling out. Download a release tarball with curl, extract it, and run it immediately. Voice commands. Tap the mic, speak a command. Apple Speech framework converts speech to text. Auto-submits on detected silence. Voice commands are saved to the scripts list for one-tap re-run. Saved scripts. Save any sequence of commands as a named script. One-tap to re-run later. Voice-recognized commands are auto-saved to the scripts list for instant replay. Mac Catalyst support. Runs natively on macOS as a Mac Catalyst app. Multi-window, resizable, fullscreen-capable. The same code that runs on your iPhone runs on your Mac. DESIGNED FOR DEVELOPERS JS Shell is a tool for people who want to test web code on a real iOS device without installing Xcode, syncing files, or setting up a tunnel. It is especially useful for: Testing geolocation, camera, and microphone permission flows on iOS. Validating fetch, CORS, and cookie behavior on a real iPhone. Building small offline web tools that need persistent state. Running JavaScript snippets without opening Safari Inspector. Debugging mobile rendering edge cases on the device itself. PRIVACY JS Shell does not collect any user data. There is no telemetry, no ads, no analytics, no third-party SDKs, no remote configuration. Everything you type, paste, or download stays on your device. The local HTTP server only listens on the loopback interface and is not reachable from any network. The app forwards camera, microphone, speech recognition, and location permissions to web pages you load, exactly like Safari does on macOS. The first time a page tries to use them, iOS shows the standard system permission prompt. The first time a page tries to use them, iOS shows the standard system permission prompt.

Build, test, and debug APIs anywhere HTTP Request is a powerful API client and debugger for iPhone and iPad. Create HTTP, GraphQL, WebSocket, and MCP requests, organize them in collections, inspect detailed responses, and catch changes before they become bugs. Build and send - Send HTTP and HTTPS with common methods, headers, query parameters, JSON, forms, multipart data, raw data, and file bodies - Write GraphQL queries and variables, inspect schemas, and review results - Connect to WebSockets, send text or binary messages, and measure ping times - Connect to MCP servers and browse tools, prompts, resources, and templates Inspect and reuse - Highlight JSON, HTML, XML, text, and binary responses; filter JSON and XML with JSONPath and XPath - Review status, headers, size, redirects, timing, ports, HTTP protocol, DNS, and TLS details - Keep searchable history and replay saved requests with their exact sent data - Organize collections, use {{variables}} from environments, and save reusable authentication profiles - Import Postman collections and environments plus OpenAPI or Swagger files; export Postman Collection v2.1 JSON - Send HTTP requests from Apple Shortcuts Advanced Labs with PRO - Compare later runs with a pinned Request Time Machine baseline - Test environments and authentication profiles in one matrix - Detect response and network changes with API Change Radar - Review MCP tool data and prompt-injection risks before a call runs - Pair a Mac and route its requests through this device's network path The free version supports up to 2 collections and 10 requests per collection. HTTP Request PRO unlocks unlimited collections and requests plus all Labs. Monthly and yearly plans renew automatically until canceled.
