Search4Faces review
A focused face-matching service with social-profile links, scores, and API access.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Search4Faces is a web-based reverse face search engine for finding similar faces in uploaded images. It combines face detection, facial recognition, and machine learning to return similarity scores and links to matching profiles. The service is aimed at users who need social-profile face matching, whether through its browser interface or programmatically through the JSON-RPC 2.0 API. Documented search sources include VKontakte, Odnoklassniki, TikTok avatars, Clubhouse avatars, and a public-persons database.
The browser interface supports free web searching, while the paid offering is built around one-time API packages with 30-day validity. The 5000 plan costs $40 for 5,000 total API calls, up to 2 concurrent connections, and up to 10 calls per minute. The 15000 plan costs $80 for 15,000 calls, 4 concurrent connections, and 15 calls per minute. The 45000 plan costs $160 for 45,000 calls, 6 concurrent connections, and 20 calls per minute. The 135000 plan costs $320 for 135,000 calls, 8 concurrent connections, and 30 calls per minute.
Its strongest fit is a focused workflow that needs face similarity searches, source-specific database coverage, and programmatic access. Face detection in uploaded JPEG and PNG images, result scores, profile links, and PHP and Python client libraries give the service a clear API-oriented shape. The trade-off is breadth: searches center on the named social and public-person databases rather than a broad general image-search ecosystem. Choose Search4Faces when those sources and usage packages match the project; consider an alternative when wider image-source coverage or different API terms matter more.
