ARM-JTAG-COOCOX is an ARM debugger based on CoLinkEx design. It is meant to work out-of-the-box with the free CooCox IDE. It works with older versions of Keil MDK and IAR EW for ARM via a plugin. Its affordable price and the ability to debug via both SWD (Serial Wire Debug) and JTAG interfaces are the product's key points.
