BuiltWith Alternatives: Free Website Tech Lookup
BuiltWith shows a site’s tech and market share, but real data starts at $295/mo and the free report is heavily trimmed and sales-oriented rather than developer-oriented. A free alternative for quickly checking one site — the website technology detector.
Free online tool — tech detect checker: instant results, no signup.
What BuiltWith is and its downsides
BuiltWith is a technology profiler and lead-gen database. For the simple job of "what is this site built with", the downsides are: pricey (useful data from $295/mo, trimmed free report), sales-focused rather than dev/audit-focused, and a cluttered report full of marketing metrics.
