Check one domain before paying for broad technographic lists
Use WhosBuilt for lightweight public evidence reports when you need to qualify a small set of sites before buying list, database, or enrichment access.
What this checks
- One-domain stack, hosting, DNS, SSL, header, creator, and contact evidence
- Prospecting context for rebuild, agency, indie, and technical research workflows
- Honest fit for low-volume verification, not enterprise list replacement
How I treat the evidence
If you need millions of records, use a list database. If you have a domain or a small shortlist, start with public evidence and decide whether the lead is worth deeper research.
WhosBuilt avoids price comparisons because vendor plans change. The practical question is whether a lightweight report answers the first qualification step.
Is this cheaper than BuiltWith?
WhosBuilt is a different workflow: one-domain evidence first. It is best for low-volume research, not for replacing a paid database when you need bulk lists.
What should I check before paying for a list?
Run a few target domains and inspect stack, hosting, contact, builder, and freshness clues. If the pattern is valuable, then broader data may be worth buying.
