### \[0.0] - 2026-10-09

#### Added

- First release.
- Detects 3,500+ technologies in 100+ categories from response headers, cookies, HTML, meta tags, script URLs, inline scripts, styles, page text, CSS selectors and (optionally) robots.txt. No headless browser.
- Fingerprints from the MIT-licensed Wappalyzer 6.10.54 data plus curated additions for modern stacks (Next.js, Nuxt, SvelteKit, Astro, Remix, GA4, Segment, Plausible, Hotjar, Intercom, Drift and more).
- Version extraction, confidence scores, implied technologies, `requires`/`excludes` rules and optional detection evidence.
- Page title, meta description, language, emails and social profile links for lead lists.
- Reliability: `www.`/`http://` fallbacks for bare domains, expired-certificate fallback, one retry for dropped connections, optional proxy retry for blocked sites, 4 MB page limit, per-site timeouts. One failing site never fails the run.
- Pay-per-event pricing: one `url-analyzed` event per successfully analysed website ($0.004); failed websites are free. Respects the user's maximum cost per run without overshooting, even with high concurrency.
