A WhatsApp status checker for your browser tracks contacts' online status without any app install or phone access. InfiniteSpy runs entirely on the web — you add a number in your browser and get online alerts and history from any device, with nothing to install on the contact's phone.
InfiniteSpy is a browser-based WhatsApp availability tool. It shows when contacts come online and go offline, with real-time alerts and activity insights — and never reads messages, calls, or media. Start a free trial →
Each feature reports availability information only — never message content, calls, or media.

Every online session is logged and browsable from any browser you sign in on.

Browser checking shows availability, never location.
InfiniteSpy never accesses messages, calls, photos, media, or location — only online availability.
InfiniteSpy runs in your browser and tracks only online availability — it never reads messages, calls, or media, and never needs access to the contact's phone. Use it for legitimate purposes such as monitoring your children or coordinating with family, and always in line with WhatsApp's terms and local privacy law.
The browser checker reflects a contact's WhatsApp availability, not what they're doing inside the app or who they're speaking with. Alerts depend on the contact's phone being connected and your browser receiving notifications. Status checking works in any modern browser but isn't a native phone app.
Start a free trial, add a contact, and see availability within minutes. Plans start at a few dollars per week and you can cancel anytime.
