What are the differences between ChatTCP online version and offline app?

ChatTCP Online vs Offline App Differences

There are basically no functional differences between the ChatTCP online version and the offline app.

The online version focuses on instant use without needing to install an app, and supports cross-platform usage. Currently, the app only supports macOS.

The offline app was launched to address users' privacy concerns.

The online version requires uploading pcap files to the server for analysis, which many people worry about data leakage. The app, except for login and subscription functions, does not connect to the internet at all and performs completely local offline analysis.

Local offline analysis has no network transmission delays, providing a better experience than the online version.

We have defined different privacy policies for the online and offline versions!

The online and offline versions also have different Pro benefit restrictions. Because the online version has server costs, we don't impose feature restrictions but only provide one free trial opportunity.

If you have no privacy concerns about using ChatTCP, or trust our privacy policy, you can use the online version with confidence.
