PimEyes blurs the match URLs until you pay $29.99 a month. Here are seven alternatives tested on the same portrait — which ones are actually free, which do real face matching, and why none of them can see a dating profile.

Short answer
PimEyes has a free tier, but it blurs the match URLs, so it tells you a face appears somewhere without telling you where. The closest genuinely free substitutes are Yandex Images and Google Lens, which match visually rather than by face. For dating profiles specifically, none of these work — those photos sit behind a login that no crawler reaches.
Partly, and the part that is free is the part you already knew. You can upload a face without an account and see how many results came back, plus thumbnails. The source URLs are blurred until you subscribe. Paid plans start around $29.99 a month for a capped number of daily searches, and climb steeply for the monitoring and takedown tier.
It is worth being clear about why: PimEyes runs continuous crawls of billions of images and stores a face embedding for each one. That is expensive infrastructure. Nobody gives it away.
Useful, in a narrow way. The free search answers exactly one question:
"Does this face appear anywhere on the indexable public web?"
If it returns zero results, that is genuinely informative and it cost you nothing. If it returns forty, you now know there is something to find and you have to decide whether the answer is worth $29.99. For a one-off question, it usually is not — which is why people go looking for alternatives.
Yandex is the only mainstream free engine that behaves anything like face search. It is not doing true face embedding, but its visual similarity model is unusually strong on portraits, and it will surface different photos of the same person often enough to be worth the first two minutes of any search. Interface is rough, results skew heavily toward Eastern European sources, and it is a Russian service — draw your own conclusions about uploading someone's face to it.
Excellent at finding where a specific image file was published. Deliberately not a face search — Google decided years ago not to offer face matching as a consumer product. Crop or filter the photo and its confidence collapses. Use it to check whether a photo was stolen from a stock library or another profile, not to identify a person.
The oldest tool here and still the most honest. It finds exact and near-exact copies of a file and tells you the earliest date it saw one. That is the single best catfish test in existence: if a "new" profile photo first appeared on a website in 2017, you have your answer. It will never find a different photo of the same person.
Actual face matching, with a credit system rather than a hard paywall — you get some free searches and earn more slowly. Its index leans toward news coverage, social media and, notably, criminal record databases, which makes it useful for a safety check before a first date and less useful for general people-finding. Result quality is inconsistent.
Free face search limited to a handful of social networks, mostly VK and Odnoklassniki with some Instagram and TikTok coverage. Genuinely free and genuinely narrow. If the person has no footprint on those networks it returns nothing, which is most people outside Eastern Europe.
Behaves similarly to Google Lens with a different index, which is the whole point of running it. Takes thirty seconds and occasionally surfaces a page the others missed. No face matching.
Not a free alternative in any sense, but it comes up constantly in this search so it is worth placing. It is a people-search service with a reverse image component, priced on a monthly subscription, and part of the work is done by researchers rather than an index. Useful for romance-scam investigations, slow and expensive for a quick question.
This is the part that wastes the most time, so it is worth spelling out. Every face search engine listed here works by crawling pages that are publicly reachable. Tinder, Bumble, Hinge, Feeld, Ashley Madison and the rest all block external crawlers in robots.txt and serve profile images from private CDNs behind rotating, expiring URLs. There is nothing for a crawler to index. A profile can be active today and completely invisible to PimEyes forever.
Searching inside those apps requires querying them directly rather than crawling them. That is what PartnerCheck does: one uploaded photo, a face match run against 50+ dating platforms in a single pass, results in under 60 seconds, nothing sent to the person in the photo. Results are possible matches from public profiles — signals to act on, not proof of identity.
Searches for "PimEyes free" attract a predictable class of website. Two patterns to walk away from:
A photo of someone's face is sensitive data. Upload it to services that state plainly what they store and for how long — and delete afterwards.
Only partially. The free tier lets you upload a face and see how many matches exist along with thumbnails, but it blurs the source URLs — so you learn that the face appears somewhere without learning where. Paid plans start around $29.99 per month to unblur results.
Yandex Images. It is the only mainstream free engine whose visual similarity model is strong enough on portraits to sometimes surface different photos of the same person. It is not true face-embedding search, its results skew heavily to Eastern European sources, and it is a Russian service, which is worth weighing before uploading someone's face.
FaceCheck.ID and Search4Faces both do real face matching with free access. FaceCheck.ID uses a credit system and indexes news, social media and criminal record sources. Search4Faces is free but limited mostly to VK, Odnoklassniki and some Instagram and TikTok coverage, so it returns little for people outside Eastern Europe.
No. Every face search engine works by crawling publicly reachable pages. Tinder, Bumble, Hinge and other dating apps block external crawlers and serve profile photos from private CDNs with expiring URLs, so there is nothing to index. Searching inside those apps requires querying them directly, which is what PartnerCheck does.
For a different job, yes. TinEye matches image files, not faces, and it tells you the earliest date it saw a copy of that file. That makes it the single best catfish test available: if a supposedly new profile photo first appeared online in 2017, you have your answer. It will never find a different photo of the same person.
Be careful. A face is sensitive biometric data. Avoid any site advertising unlimited free face search with no signup — running a face index is expensive, so free access is usually monetised through your uploads or your email. Also avoid sites that show a results count before a search could plausibly have finished, then ask for a card to unlock it.
Use a dating-app-specific search rather than a general face search engine. PartnerCheck runs one uploaded photo against 50+ dating platforms including Tinder, Bumble, Hinge, Feeld and Ashley Madison in a single pass, returns in under 60 seconds, and sends nothing to the person in the photo. Results are possible matches from public profiles rather than proof of identity.
