TyTools
TyTools is a collection of tools for uploading firmware to Teensy boards. It nicely handles more than one Teensy and has a very good serial monitor. There is also an option to directly integrate tyTools to the Arduino IDE.

TeensySharp
Teensy Sharp provides some helper classes for C# Windows applications which communicate to PJRC Teensy boards. Currently the following common tasks are handled:
- Uploading of firmware (ihex files) from within the user application.
- Finding all Teensies on the USB tree (get a list with entries for each found board containing its serialnumber and the name of the COM port to which it is connected)
- Provide information when a Teensy is connected or removed from the USB Tree
