Loads and saves CAN frames in many log formats, including BusMaster, Microchip, CRTD, GVRET, CSV, Vector Trace, IXXAT Minilog and Vehicle Spy.
Captures live CAN traffic through any Qt SerialBus driver, such as socketcan, Vector, PeakCAN or TinyCAN.
Reads CANDump, Kayak, PCAN Viewer and Wireshark socketcan PCAP files, which it can only load, not save.
Recommends the CANDue board from EVTV running GVRET firmware as a capture device, though none is required.
Targets visualization, reverse engineering and debugging of CAN bus traffic.
Has a work-in-progress Qt 6 branch, described as beta quality.
