Packet Sender is an open source utility to allow sending and receiving TCP, UDP, and SSL (encrypted TCP) packets as well as HTTP/HTTPS requests (GET, POST, PUT, PATCH, and DELETE) and panel generation. The mainline branch officially supports Windows, Mac, and Desktop Linux (with Qt). Other places may recompile and redistribute Packet Sender. Packet Sender is free and licensed GPL v2 or later. It can be used for both commercial and personal use. If you find the app useful, please consider donating/sponsoring so development may continue.

iOS Mobile App

The Packet Sender for iOS is fully native, contain bare minimum permissions, and collects no data. This is software that respects you. Thank you for supporting this effort.

The iOS version is located on the Apple App Store (opens in a new tab)

Packet Sender is identical for all the desktop versions. The only difference is its theme to match the operating system.

• A packet has a name, destination address (domain names are default resolved just before sending), port, and data associated with it.
• In the table, there is a list of saved packets. You can double-click to directly edit fields in this table.
• In the bottom right, there are UDP, TCP, and SSL server status and port(s). Clicking on these will activate or deactivate the protocol. Packet Sender supports binding to any number of ports.
