A Windows CAN-bus tool for ESP32 and MCP2518FD hardware, with live decoding, DBC support, session replay, and signal plotting.

Landing page captured for the 2026-11-07 issue.

For: Automotive technicians and CAN-bus hobbyists
Worth noticing: Compare freezes a baseline, then highlights the CAN ID and byte that changed after a control is triggered.

Field notes

The setup instructions specify an ESP32 with an MCP2518FD controller and USB firmware connection at 921600 baud. The page lists session save/replay and signal plots alongside the Compare workflow, and publishes an installer SHA256 checksum. It also describes a FIAT Stilo dictionary add-on as tested; the browser-based Web UI is separately marked as in testing.
