Reverse Image Search Anywhere — browser extension

Multi-engine reverse image search that also works where the plain "search by URL" trick fails — Instagram, Pinterest, <canvas>, blob: and data: images — plus clipboard paste, region capture, and a face-search-first flow.

The privacy claims on the product site — plain searches never touch our servers, and uploads (only when you ask) get a link that expires after 15 minutes, and once it does nobody can reach the file; the file itself is deleted automatically about a day after it arrives — are the main reason to install this over an alternative. They are worth nothing if you have to take them on trust. This is the code, so you don't.

Start with entrypoints/background.ts for the context-menu and search routing, lib/config.ts for every server address the extension knows about, and lib/engines.ts for the engine definitions.

Requires Node 24 (the line CI builds against). Add-on-store build notes quote the exact version each submitted package was built with, measured at release time — it does not have to match your local patch version.

npm ci
npm run dev            # launches Chrome with the extension loaded + hot reload
npm run dev:firefox

Then right-click any image on a page → Reverse image search.

npm run compile        # tsc --noEmit
npm test               # vitest

Suites in lib/store-listing-completeness.test.ts and lib/menu-label-parity.test.ts check copy that lives in the private monorepo — store-listing drafts and the Rails view templates — and skip automatically here. Expect about half the suite to skip in this repo; that is correct, not a broken checkout.

npm run zip            # chrome
npm run zip:firefox
npm run zip:edge
npm run zip:opera

Output lands in .output/. With the pinned Node version and the committed package-lock.json, the build is deterministic: a clean rebuild reproduces the shipped bundle byte for byte.

This is a read-only mirror, published with git subtree from a private monorepo that also holds the Rails backend serving reverseimage.app. The monorepo is the source of truth, so commits land there and are pushed here — which is why this repository has no branches other than main and no direct commits.

Issues and pull requests are welcome regardless; a PR here will be applied upstream by hand and credited.

Store performance for this extension — keyword rankings, installs, ratings, and listing changes across the Chrome Web Store and Firefox Add-ons — is tracked with ExtensionDash, extension analytics made for agents: it serves the data over MCP, so a coding agent can answer questions like "which keywords gained rank this week?"
