Request12 is a focused API debugging tool built for iOS developers, QA engineers, and technical teams that need fast visibility into web traffic. Use the built-in browser to load a page, capture network calls, inspect details, and replay requests with edits in a sandbox environment. What you can do - Browse any target URL in an embedded webview. - Automatically capture `fetch` and `XMLHttpRequest` traffic from pages loaded in the app. - View method, status, timestamp, full URL, headers, request body, and response body. - Filter traffic by method and search by URL/status/error. - Inspect JSON with pretty print and syntax highlighting. - Copy URL, request body, response body, and payload sections in one tap. - Send captured requests directly to Sandbox. - Edit method, URL, headers, and body before execution. - Execute with cookie sync support from the browser context. - Review response status, latency, headers, and body for fast validation. - Switch between Light, Dark, and System themes. Request12 is designed for fast iteration: - Reproduce issues from real traffic. - Validate backend changes quickly. - Compare original vs modified requests. - Test custom headers and payload variations on mobile. Notes Request12 captures traffic generated inside the app browser context and sandbox workflow. It is intended for authorized testing and debugging use cases.

About

JSON Pilot

Features

A native JSON viewer and editor for iPhone, with an on-device AI assistant that explains your data without sending a byte to the cloud. JSON Pilot opens any JSON โ€” from Files, the share sheet, AirDrop, your clipboard, or an HTTP request you fire from inside the app โ€” and gives you three ways to read it: a syntax-highlighted Tree, a tap-to-edit Fields drilldown, and a Text view with line numbers. Edit at any level, prettify or minify, validate with a precise line:col error, and Save the edits back to the original file. โ€” FREE FOREVER โ€” The whole viewer and editor is free with no account, no nags, no cloud sync. View, edit, validate, format, minify, search, Save, Save to Files, Share, Copy. We never gate the basics. โ€” ON-DEVICE AI ASSISTANT โ€” Ask "What is this JSON?" or "Find issues" or "Extract all emails" and JSON Pilot answers locally, using Apple Foundation Models. Your JSON, your prompts, and the model's replies never leave your iPhone. No server, no API key, no cloud fallback. (The AI assistant requires an Apple-Intelligence-capable iPhone โ€” 15 Pro and the full 16/17 family. On other devices the assistant is automatically disabled; everything else in the app still works.) โ€” POWER TOOLS (PRO) โ€” โ€ข JSON Diff โ€” compare two payloads by structure. Reformatting is never a change. Summary view groups Changed / Added / Removed; Unified view shows a GitHub-style line diff. โ€ข JSONPath queries โ€” $, ., [i], [*], .. and more. Matches highlight right on the Tree. โ€ข Format conversion โ€” export to YAML, CSV, or XML. โ€ข HTTP request tool โ€” send GET / POST / PUT / PATCH / DELETE with custom headers, open the JSON response in the same workspace. โ€ข Auto-fix โ€” repair broken JSON: trailing commas, single quotes, unquoted keys, comments, smart quotes. โ€ข Themes โ€” accent color and three syntax palettes. โ€” PRIVACY YOU CAN VERIFY โ€” Zero analytics SDKs. Zero telemetry. Zero crash reporters. The only network traffic the app initiates is StoreKit (your purchases) and HTTP requests you fire yourself. Recents are stored locally โ€” CloudKit is explicitly disabled. JSON Pilot does not request Camera, Photos, Contacts, Microphone, Location, or any other iOS permission. โ€” UPGRADE TO PRO โ€” Two ways to unlock the same Pro features: โ€ข Monthly subscription โ€” billed monthly, cancel anytime. โ€ข Lifetime โ€” one-time purchase, keep Pro forever. Both options unlock the same features. See the App Store listing for current pricing in your region. Manage or cancel anytime in iOS Settings โ†’ Apple ID โ†’ Subscriptions. โ€” REQUIREMENTS โ€” iPhone running iOS 26.4 or later. AI features require an Apple-Intelligence-capable iPhone. โ€” SUPPORT โ€” Questions, bugs, ideas?
