Packet Sender - The UDP and TCP Network Test Utility

Packet Sender is an open source utility to allow sending and receiving TCP and UDP packets. It is available free (no ads / no bundleware) for Windows, Mac, and Linux. It can be used for both commercial and personal use (license). It's designed to be very easy to use while still providing enough features for power users to do what they need.


The native mobile versions have been abandoned to focus on the more popular and more capable desktop version. However, the GitHub projects for both iOS and Android are MIT Licensed and available for forking.
