The 98 sites in the search
The platforms people use most, picked because they return a full profile rather than a yes or no. Each one stays on the list only while it passes a test from our server: a known account has to come back as a profile, and a made-up handle has to come back as missing.
Last tested 14 October 2026. Want more? Seer searches 700+ platforms, including Xbox, Last.fm and ArtStation.
