#showdev: CAN Playground — a local-first CAN bus analysis tool

CAN Playground is a local-first desktop CAN bus analysis tool built with Tauri, designed for reverse engineering and security work where signal documentation is unavailable. It offers multiple analysis views including hex dump with delta highlighting, delta graphs for pattern detection, and bit-level timeline maps, all running entirely offline with no telemetry. The tool addresses the workflow fragmentation common in traditional CAN analysis by keeping all exploration within a single context.
