WhosBuilt
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.
