WebPeek
Web developer tools inside Safari, for iPhone and iPad.
WebPeek brings the four panels you already know to Safari on iOS and iPadOS. Turn it on once and every page gets a small floating button; tap it and the inspector opens over the page you are already reading. No cable, no desktop, no account.
What it does
Elements
Tap the picker, then tap anything on the page. A real DOM tree with a breadcrumb, live attribute/text/HTML editing, matched CSS rules and a box-model diagram.
Console
Every console.* call from the first line of the page, uncaught
errors with stack traces, expandable object trees, and an input line for
running expressions.
Network
fetch, XHR, WebSocket, sendBeacon and EventSource as they happen — status, size, timing breakdown, headers and bodies. Copy as cURL or export HAR.
Storage
localStorage, sessionStorage and cookies with full editing; an IndexedDB browser with paging; Cache Storage including what a Service Worker cached.
Honest about limits
iOS gives Safari extensions a smaller toolbox than a desktop browser, and WebPeek says so instead of pretending. HttpOnly cookies stay invisible, pages with a strict Content-Security-Policy cannot run expressions, static files arrive without headers, and cross-origin responses only show the headers the server chose to expose. The in-app Tips screen explains each one and why.
Privacy
WebPeek reads only the page you are looking at, keeps everything on the device, and has no account, no analytics and no network calls of its own.
