Iframe Detector — Inspect & Highlight Frames

About

Ever wondered what's hiding inside a page? 🕵️

Iframe Detector shows you every iframe on any website — the good, the sketchy, and the "wait, when did that get there?" ones. Open the popup, and you instantly see them all.

✨ What you get
🎯 One-click scan of the page you're on — even iframes tucked away in Shadow DOM

🟢 🟡 🔴 Color-coded by origin so you know what's safe, what's cross-origin, and what's an ad or tracker

✨ Highlight any frame right on the page with a soft pulsing outline

🔎 Search by URL and filter by visible / hidden

📋 Copy a URL with one tap

📊 Export to JSON, CSV, or Markdown — or straight to your clipboard

🔬 Dig into the details
Tap any frame to see:

Where it's loaded from

Its size and visibility

Sandbox settings

A copy-ready <iframe> snippet for your bug report or docs

⏱️ Activity timeline
Iframes come and go. This extension keeps a tidy log of what appeared, what disappeared, and how long each one stuck around. Great for chasing down lazy-loaded ads, flaky embeds, or anything that loads a beat too late.

🎨 Built to feel nice
Light and dark themes

Cozy or compact layouts — pick your vibe

Clean, quiet, and out of your way

Speaks 55+ languages (every locale Chrome supports 🌍)

🔒 Privacy you don't have to think about
Your data stays on your device. Full stop.

No URLs, no page content, nothing ever leaves your browser

Zero third-party requests

Preferences and history live in local storage

Optional anonymous usage counts (off by default) — and even those are just "feature X was opened," nothing about you or the pages you visit

Only two permissions, both earn their keep:

activeTab — reads iframes on the tab you're looking at, only when you open the popup

storage — remembers your theme and history between sessions

👩‍💻 Who's it for?
Devs debugging embeds, analytics, or payment widgets

QA folks checking what actually loaded

Security-curious people auditing cross-origin stuff

Performance nerds hunting down late-injected frames

Anyone who just wants to know what's on the page

Pop the hood on any webpage. You'll be surprised what's in there. 🚀
