## Changelog

### 1.0 (2026-10-07)

- First version.
- Detects technologies from the homepage (and up to two more pages that robots.txt allows): HTML, script and link URLs, meta generator, cookie names, response headers, plus MX and TXT records over DNS-over-HTTPS for the email provider and verification records.
- Our own fingerprint file (src/fingerprints.json) with categories and versions where visible; extends the detection that the audit Actors share.
- Lead-list filters: must use / must not use, category filter.
- Free summary row with technology counts across the list.
- Pay per event: `site-analyzed` at $0.002. Sites filtered out and error rows are free.
