Catvu is an IMVU tracking and analytics service that brings room activity, snapshots, outfit changes, and social signals into one dashboard, with notifications delivered through Discord. Its tools include room and user searches, live monitoring of public-room participants, activity histories, and a Radar Bot that alerts subscribers when selected users appear in rooms or change their profiles. Additional features track outfits, follows, friend requests, recurring hangouts, and overlap between users, with timelines and weekly summaries to help organize these observations.

Catvu also offers a VIP Music Bot and a private-room tracker, though the site emphasizes that its Radar and chat-monitoring features cover public-room signals; private rooms are described as remaining private. Chat Spy can join a watched user in a public room to capture room conversation and send keyword alerts. The service supports watchlists of up to 25 people, configurable notifications, and quiet hours. Catvu advertises a founder beta subscription at $59 per month, with access arranged through Discord login and PayPal.
