Trace-X vs WHIMO

Trace-X is an open-source system for tracking parts and their relationships along a supply chain. It can ingest data about serialized parts, batches and child components. Users can search and filter manufactured parts represented by BoM AsBuilt and planned parts represented by BoM AsPlanned. Part details include Asset Administration Shell descriptions and models for serial parts, batches, just-in-sequence processes, planned and built bills of material, and usage. A parts tree shows component relationships, while supplier-network and supply-chain views let users inspect connections. Quality workflows support investigations exchanged between a company and supplier, plus alerts sent by a company to customers. The project aims to support standardized, interoperable and data-sovereign traceability exchange within Catena-X, with access defined for participating companies and people. Its browser frontend is an Angular application served statically through NGINX. REST endpoints are documented with the OpenAPI Specification, and the project provides a Swagger UI path. The installation guide documents deploying the application with a Helm chart. In the local umbrella setup, sending and receiving quality notifications is out of scope because that requires another Trace-X instance.

WHIMO captures and shares supply-chain transaction and geolocation data from origin to destination. It is designed for cooperatives, local aggregators, transporters, processors, and exporters, including people working in low-infrastructure contexts. Users can record buying, collecting, selling, and delivery transactions, track traded volumes, document raw materials becoming processed products, and review transaction history. Farm locations can be added by scanning QR codes, recording GPS locations, dropping map pins, or entering geolocation later. WHIMO can display supply chains across direct and indirect suppliers, measure geodata coverage for transactions, and help users request missing location data. Participants can collect traceability information from suppliers, transfer it to customers, view supply-chain diagnostics, and download data for due diligence. The service is available on Android, iOS, and the web, with an option to self-host. The European Forest Institute hosts a ready-to-use version and manages its data under its data policy; companies and institutions can also replicate and adapt the open-access source code for their own system. WHIMO is free and based in Joensuu, Finland.
