How to detect Base44 websites
The all-in-one AI app builder acquired by Wix
Base44 is an all-in-one AI app builder (acquired by Wix in 2025) that generates complete applications with hosting, auth and a database included. Because the platform hosts everything by default, Base44 apps carry strong, hard-to-remove fingerprints at both the DNS and HTML level.

- ✓
Subdomain on base44.app (default hosting) - ✓
base44.com asset or API URLs in HTML source - ✓
Built-in Base44 auth widget markup - ✓
Platform API calls to base44 endpoints in bundled JS - ✓

Frequently asked questions
Are Base44 apps always on base44.app domains?+
By default yes, and most stay there — Base44 targets non-developers building internal tools, who rarely attach custom domains. When they do, the platform's API calls in the bundled JavaScript still reveal the origin.
Did the Wix acquisition change Base44 fingerprints?+
The product continues to run on its own infrastructure, so base44.app and base44.com markers remain the primary signals. If migration to Wix infrastructure happens later, Wix's own fingerprints (parastorage CDN, wixsite patterns) would apply.
Is a Base44 app 'vibe coded'?+
Yes — Base44 is squarely a vibe coding tool: users describe the app in natural language and the platform generates and hosts everything. Our detector counts a Base44 fingerprint as a strong positive signal.
