## Changelog

### 2026-10-03

- First release: bulk tech stack detection for URLs and bare domains with ~3,600 open-source fingerprints (Wappalyzer 6.10.54, MIT) in 108 categories.
- Detects technologies from HTTP headers, cookies, meta tags, script URLs, inline scripts and styles, HTML and DOM patterns, and public DNS records (MX, TXT, NS, CNAME, SOA).
- Each technology comes with categories, version, confidence (0-100), website and the evidence types that matched.
- Every row has a status: COMPLETE, PARTIAL, VALID\_EMPTY, INVALID\_INPUT or UPSTREAM\_FAILED. Only COMPLETE and PARTIAL websites are charged ($0.003 each); empty, invalid and failed websites are free.
- Polite by design: one page request per website, configurable concurrency, timeouts, retries with backoff, private-network blocking.
- Platform usage included in the price; subscriber discounts on paid Apify plans.
