CANcorder

CAN bus logger and analyzer for automotive diagnostics

CANcorder main window

CANcorder connects to CAN hardware via TCP, J2534 PassThru (Windows), SocketCAN (Linux), or supported USB adapters on macOS, displays CAN frames in real-time, and decodes ISO-TP messages with protocol hints for UDS, OBD-II, and KWP2000. Whether you're reverse-engineering ECU communications, debugging a vehicle network, or analyzing recorded logs, CANcorder provides the tools you need.

Features

Live CAN Frame Capture

Connect to your CAN interface and watch frames arrive in real-time. Filter by arbitration ID, search for specific patterns, and pause capture to analyze traffic.
