A collection of Linux user-space utilities for the SocketCAN subsystem, written in C. It includes tools to display, send, generate, record, replay, and analyze CAN and CAN FD traffic, plus ISO-TP and J1939 tooling.

Use cases

• dump and log CAN bus traffic on Linux
• replay recorded CAN log files
• generate random CAN frames for testing
• sniff ISO-TP messages over CAN
• test J1939 communication on an agricultural vehicle bus
• measure CAN bus load
• bridge TCP/IP to ISO-TP or SocketCAN

When to choose

• you work with SocketCAN on Linux and need standard command-line CAN tools
• you develop or debug automotive or industrial CAN/CAN FD devices
• you need ISO-TP (ISO 15765-2) or SAE J1939 utilities
• you want to record, convert, and replay CAN traffic

When to avoid

• you need CAN tooling on Windows or macOS without Linux SocketCAN support
• you want a GUI CAN analyzer rather than command-line tools
• you need a high-level application-layer protocol stack rather than utilities
