Tech stack lookup: a BuiltWith alternative for public evidence
Look up a company’s observed vendors with dates and source links. Compare this disclosure-and-job-board approach with website technology detection tools.

Partial covered stack
Public-source observations. Observation dates are review dates, not adoption dates.
BuiltWith offers website technology lookup, trends, and related prospecting data. Wappalyzer also provides website technology detection. VendorCensus’s current lookup searches a small reviewed collection of public recruiting boards and vendor disclosures.
Compare alternatives by the question they answer
Website detection can help answer what is visible on a site. A subprocessor disclosure can reveal a processing relationship behind a service. These approaches overlap in some cases but are not interchangeable.
We do not claim competitors lack history, or that VendorCensus has broader coverage. Check the source type, historical depth, entity matching, and export rights relevant to your question.
BuiltWith pricing and free lookup
The comparison below links to current official pricing and distinguishes individual free lookups from paid datasets. VendorCensus’s public snapshot lookup is free and returns available evidence before any signup. It does not scan an unknown domain live.
A public job board supports an ATS observation. A subprocessor disclosure identifies a provider that may process data for particular services. A vendor customer story describes a published relationship. These sources have different scopes and are labeled separately.
Counts cover the records on these pages, not the whole market. No observation in our covered sources does not mean a company does not use a vendor. Source recency and unresolved conflicts affect confidence; observations do not establish spend, renewal timing, or customer churn.
