Kameleo 5.1, released on August 3, 2026, introduced Fingerprint Inspector, and on August 10 the company described it in detail on its blog. It is a DevTools tab that shows in real time which fingerprinting calls the open website is making.
The inspector is launched from the profile’s context menu. The panel displays rows with the timestamp, API name, parameters, and returned value. Events are grouped into categories: Canvas, WebGL and WebGPU, audio processing, navigator properties, media devices, WebRTC, geolocation, Bluetooth, and speech synthesis voices. The panel collects calls from all tabs in the profile, and events can be searched.
Similar tools such as JShelter and FPMON work as extensions and replace JavaScript functions. A website can detect this and stop running its checks. Kameleo embedded C++ interceptors directly into the Blink engine, so the APIs visible to the page do not change. According to the company, the idea was inspired by a post from the researcher Veritas about their own Chromium fork.
At launch, the inspector worked only in Chroma. According to the browser kernel release page, its capabilities were added to Junglefox 153 on October 5, 2026, while Chroma gained a callerSource field for events, containing the file, line, and column of the script that made the call. As of October 9, the documentation still says that Junglefox is not supported.
Who it is useful for: Anyone trying to understand why a specific website considers a profile suspicious.
