Open databaseResearch websites detected using core-js
Use these core-js detections as a starting point for stack research or prospect qualification. Open a domain report to inspect related technologies and observation dates before saving a shortlist.
Combine included and excluded technologies in the database, review estimated country, and verify the signals that matter to your work. A detection does not establish buying intent or a verified company location.
Narrow your shortlist
Country previews require a geography score of at least 70 and 50 qualifying domains. Geography is estimated from website signals, not a verified company address.

How to read this preview
This technology cohort includes domains with a successful stored scan and a detailed observation of this technology scoring at least 70. Country previews additionally require at least five meaningful technologies and a geography score of at least 70. Rows show when core-js was observed; a dated detection is not a live verification. Rule scores summarize fingerprint evidence and are not measured accuracy percentages. The public preview and paid database use different eligibility rules.
Open a website report, check the observation dates and relevant signals, then save matching domains in the database. Pro includes CSV lead-list exports and 500 monthly enrichment credits; Business includes 5,000. Enrichment does not provide contact details or buying intent.
