BuiltWith alternative
A focused BuiltWith alternative for quick website lookups
Run a free lookup for public stack, hosting, DNS, headers, SSL, registrar, creator, and brand signals without starting from a giant report.
Try:
What this checks
- Tool-first lookup above the fold
- Public technology and infrastructure evidence
- Saved history and deeper comparison paths for logged-in users
How I treat the evidence
BuiltWith is useful. WhosBuilt is narrower: quick public evidence for one domain, with lead-friendly context around who built and hosts it.
Start with one free lookup. If the domain matters, use the full report and save it for comparison.
Is WhosBuilt a full BuiltWith clone?
No. It is a leaner checker for public website signals, creator clues, and infrastructure context.
When should I use this instead?
Use it when you want a fast answer for one domain and enough evidence to decide whether the lead is worth saving.
