Lens 3 · Browser Extension

Run reverse-image search from your own browser.

Some search engines block our datacenter IPs. Install this extension and your browser queries Yandex, Google Lens, Bing Visual, TinEye, and others from your residential IP — the way they expect real traffic. We never see those queries, and your existing scan results get dramatically better recall.

Why this exists

Yandex, TinEye, and Bing Visual challenge datacenter connections by default — even the best proxy infrastructure sees ~30% of reverse-image queries fail with HTTP 403. Your home internet has a residential IP that those engines treat as a legitimate human. The extension queries them on your behalf, ships the results back into your scan tab, and never logs anything we can see.

Install (manual, ~2 minutes)

  1. Download the extension folder from our open-source repo (link pinned in the GitHub badge at the bottom of this page once published).
  2. In Chrome / Edge / Brave: open chrome://extensions, toggle Developer mode (top right).
  3. Click Load unpacked, point at the folder you downloaded.
  4. The Unimpersonationable badge appears in your toolbar. Pin it.
  5. Run a scan on unimpersonationable.com/scan — the extension auto-attaches and harvests engines we can't reach from our servers.

Open source — verify what it does

Every line of code that runs in your browser is published. Read it, audit it, fork it, build your own. We'd rather you trust the source than trust us.

Repository pin coming once we cut the public release. Until then, the source is shipped as part of our main monorepo at /extension.
