Busymate DevTools vs DevSnoop

Busymate DevTools is a network debugging tool for developers. It captures the HTTP and HTTPS requests made on your device, so you can inspect headers, bodies, status codes, and timing while you build and debug your own apps and websites. It works like a desktop web-debugging proxy, but runs entirely on your iPhone or iPad — no Mac and no Wi-Fi proxy configuration required. WHAT IT DOES • Captures DNS and TCP traffic system-wide using Apple's NetworkExtension (a local, on-device VPN tunnel — nothing is routed through our servers). • Decrypts HTTPS only for the specific domains you add to the SSL-proxy list. Everything else stays end-to-end encrypted and is passed through untouched. • Shows every request/response pair in a real-time feed: method, URL, status, headers, query, and body. • Optionally syncs captures to your private Busymate dashboard at dash.busymate.dev so you can inspect them on a bigger screen, search, tag, and export to HAR. ADVANCED • Traffic rules — block, mock, or rewrite requests and responses that match your own rules, so you can test how your app handles errors, edge cases, and slow or missing responses. • Upstream proxy — optionally route a device's outbound traffic through an external proxy you have configured. • Deep links — open the app straight to a device or a request from a link. YOU ARE IN CONTROL • Capture never starts until you explicitly turn it on and accept the on-screen disclosure. • HTTPS is only ever decrypted for domains you choose. Add and remove them at any time. • Decryption requires installing and trusting a root certificate, used only to decrypt your own HTTPS traffic for the domains you choose — guided step-by-step inside the app. • You can stop capturing and remove the VPN profile from iOS Settings at any time. PRIVACY Busymate DevTools is built for inspecting traffic from apps and sites you own or are authorized to debug. Captured data can include sensitive values such as tokens and credentials, so only inspect domains you understand and control. Synced captures are stored under your own account and can be deleted at any time. See our privacy policy at busymate.dev/privacy. REQUIREMENTS • iOS / iPadOS 16.0 or later. • A free Busymate account (sign in with Apple or email) to pair the device and, optionally, sync captures to the dashboard. Busymate DevTools is intended for developers, QA engineers, and security testers working on their own software. It is not a tool for intercepting other people's traffic.

DevSnoop is a web browser with a full developer tools panel built in, for iPhone and iPad. Build a page, load it in DevSnoop, and inspect it right there — no laptop, no cable, no remote debugging setup. DevSnoop's tools work only on pages you open inside DevSnoop, on your own device. WHAT'S INSIDE Console — Live log stream with filter chips for error / warn / info, keyword search, and a JavaScript REPL for evaluating expressions against the page you're testing. Errors, warnings and logs carry the complete stack trace — tap to expand it, just like a desktop console. Download the whole log buffer to a file in one tap. Smart-quote autocorrect is off, so code runs exactly as you typed it. Network — See every request your page makes. fetch() and XMLHttpRequest calls show full headers and bodies; static resources (CSS, scripts, images, fonts, manifest, the main document) are surfaced via the Resource Timing API. WebSocket connections appear too, with a live log of sent and received frames. Tap a row to load its response body on demand, copy it as a cURL command or a fetch() call to reproduce outside the app, or export the session as a standard HAR file you can open in Chrome or Firefox DevTools. Elements — Walk the live DOM tree, expand nested elements, and tap to highlight a node on the rendered page. Useful for tracking down a stray z-index or unexpected CSS inheritance. Storage — Inspect and edit local storage, session storage and cookies for the page you're testing, including the full cookie attribute set (domain, path, expiry, Secure, HttpOnly, SameSite). Edit a value, refresh, and watch how your page responds. BROWSER ESSENTIALS — Tabs, with private tabs that use a non-persistent WebKit data store: cookies and cache stay in memory and are discarded when the tab closes. — Tab session restoration on next launch. — Bookmarks, browsing history, and an editable Quick Access grid (long-press a tile to rename, change the URL, or delete it). — Search engine choice: Google, DuckDuckGo or Bing. — Clear browsing data selectively — history, cookies and site data, or cache. — Support for the modern web APIs your pages expect: getUserMedia (camera and microphone), navigator.geolocation, and WebKit-backed media playback. — Pull-to-refresh, offline error pages, and a mail-app chooser so links open where you want them. PRIVACY — Your browsing history, bookmarks, open tabs and Quick Access shortcuts are stored only on your device. — No accounts, no advertising SDKs, no selling of your data. — Product analytics are strictly opt-in: you're asked once on first launch, nothing is collected until you agree, the data is anonymous (no account, no URLs, no page content), and you can change your choice anytime in Settings. — Crash reports go to Sentry for stability monitoring and never include URLs, page content or personal data. — Full privacy policy: devsnoop.app DevSnoop is a development and testing tool. Its inspector is intended for debugging and testing your own web pages, for learning how the web platform works, and for accessibility and QA checks on sites you are responsible for. Built for the developer checking a layout fix on a real iPhone, the QA engineer running through a release candidate on a test device, the student learning how the DOM and the network stack fit together — and anyone who has wished mobile Safari had a real DevTools panel.
