TracePatch

TracePatch is a web app (with an optional lightweight desktop agent) for managing firmware updates and configuration changes across fleets of embedded Linux and MCU-based devices in the field. It focuses on the ugly, expensive part most teams botch: safe rollouts, version traceability, and post-update verification. You get staged deployments (canary to full), device health checks before/after flashing, automatic rollback rules, and a tamper-evident audit log for compliance and customer disputes. It supports common update patterns like A/B partitions (RAUC/Mender-style), signed artifacts, and delta updates where possible. The app also collects crash logs and key metrics tied to firmware versions so you can correlate failures to specific builds and hardware revisions. This is not a consumer app; it’s B2B infrastructure for teams that already ship hardware and are bleeding time and money on manual updates and inconsistent field behavior.
