Score: 6.5/10 (Innovation: 7, Technical: 6, Documentation: 8, Utility: 5)

Trier OS is an offline-first, full-stack plant operations system that enables technicians to instantly start work orders by scanning machine QR codes, eliminating keyboard input. It's interesting because it combines a PWA with an embedded IDE for live modifications, deterministic simulation for change validation, and GIS mapping, targeting industrial environments with unreliable connectivity.

Target audience: devops, backend devs
