Fully **local** detection of 82 technologies — frameworks, CMS / site builders, architecture (microfrontends), build tools, state/data, UI, auth, payments, observability, analytics, and hosting hints. No cloud matching, no page upload.

## What’s new in 1.8.0

A full engine and runtime audit ([docs/AUDIT-2026-09.md](docs/AUDIT-2026-09.md)), with every finding fixed and pinned by a test. Details: [docs/RELEASE-1.8.0.md](docs/RELEASE-1.8.0.md).

| Measured on 48 real sites | 1.7.2 | 1.8.0 |
|---|---|---|
| Toolbar badge matches the popup | 21 / 48 | **48 / 48** |
| Confirmed wrong results | 9 | **0** |
| Technologies | 64 | **82** |
| Tests | 134 | **433** + 17 real-browser checks |

- **More precise:** a page element with `id="next"` can’t fake Next.js; words in file names, search queries or page text never count as proof; Tailwind and version numbers are no longer mis-read (no more “Next.js v1.0.0-beta.9” on linear.app or Bootstrap on clerk.com).
- **A badge you can trust:** a background probe runs after each page load, so the badge counts what the popup shows. Rescan re-reads the page, scans time out instead of hanging, and SPA navigation rebuilds the badge.
- **18 new technologies:** Astro, Gatsby, Qwik, Preact, Lit, Polymer, Ember, AngularJS, Alpine.js, htmx, WordPress, Shopify, Webflow, Framer, PostHog, Plausible, Fathom, Amplitude.
- **Proven on real sites:** 46 real pages are captured into a golden corpus and replayed on every `npm test`; CI runs lint, type checks, coverage and the real extension in Chromium.

## Features

- Hybrid scan: light pass on navigate, then a background MAIN-world probe, so the
**badge counts what the popup shows**; the popup always runs a fresh deep scan
- Confidence tiers + expandable evidence (why it matched)
- Evidence from asset URLs (host + path, never the query), runtime objects with the
right shape, and probed DOM flags — never page text, data islands or file names
- Core stack headline + Copy / Markdown / JSON export
- React detection aligned with React DevTools (renderer registered, not bare hook)
- Microfrontend platforms: Module Federation, single-spa, qiankun, SystemJS
- Observability includes Sentry, Datadog, **New Relic**, LogRocket, and more
- **One-click core stack:** a headline such as *Next.js 14.2.32 · React · Webpack*, then every detection grouped by category
- **Confidence you can read:** high / medium / low, with weak signals listed under “Lower confidence — verify before trusting”
- **Evidence for every result:** expand a row to see the exact script, runtime global or DOM marker it matched
- **Badge while you browse:** a light pass on load plus a background MAIN-world probe, so the badge counts what the popup shows; opening the popup always runs a fresh deep scan
- **Proof, not prose:** evidence comes from asset URLs (host + path, never the query), runtime objects with the right shape, and probed DOM flags — never page text, data islands or file names
- **React detection aligned with React DevTools** (a registered renderer, not the bare hook)
- **Microfrontends:** Module Federation, single-spa, qiankun, SystemJS
- **Export** as plain text, Markdown or JSON; **Wrong?** opens a prefilled GitHub issue you review yourself
- **Private:** runs entirely on your device, no account, nothing uploaded
