DevSnoop - Developer Browser

Mobile Web DevTools

Free · Designed for iPad. Not verified for macOS.

Real DevTools in a mobile browser: live console, network + HAR, WebSocket frames, cookies, storage and the DOM. Inspect any site — no Mac required. DevSnoop is a full web browser with developer tools built in — on your iPhone/iPad. Inspect any page, debug any site, and replay any fetch without reaching for your laptop. WHAT'S INSIDE Console Live log stream with filter chips for error / warn / info, keyword search, and a JavaScript REPL so you can evaluate expressions against the current page. Errors, warnings, and logs capture the complete stack trace — tap to expand the full trace, just like a desktop console. Download the entire log buffer to a file in one tap. Smart-quote autocorrect is disabled so the code runs exactly the way you typed it. Network Intercepts every request the page makes. fetch() and XMLHttpRequest calls capture 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 every sent and received message frame. Tap any row to load its full response body on demand, or export the whole 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 any node directly on the rendered page. Useful for tracking down stray z-indexes or unexpected CSS inheritance. Storage Read and edit local storage, session storage, and cookies — with full per-cookie metadata (domain, path, expiry, secure, HTTP-only, SameSite). Change a session token, refresh, see what breaks. BROWSER ESSENTIALS — Tabs with private (incognito) mode using a non-persistent WebKit data store. Nothing written to disk. — Tab session restoration on next launch. — Bookmarks, browsing history, and an editable Quick Access grid (long-press a tile to rename, change URL, or delete). — Search engine choice: Google, DuckDuckGo, or Bing. — Clear browsing data selectively — history, cookies and site data, or cache. — Full support for the modern web APIs sites expect: getUserMedia (camera and microphone), navigator.geolocation, and WebKit-backed media playback. — Pull-to-refresh, smart offline error pages, and a mail-app chooser so links open in the app you actually use. PRIVACY — Your browsing history, bookmarks, open tabs, and Quick Access shortcuts are stored only on your device. — No user 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 — they never include URLs, page content, or personal data. — Incognito tabs leave no trace. — Full privacy policy: devsnoop.app Built for the developer who needs to debug a payment flow on a customer's WiFi, the QA engineer testing a release candidate on a personal device, and anyone who's wished mobile Safari had a real DevTools panel. If that's you — DevSnoop is for you.
