Only tools with a measurable effect make it into our stack. Below are the nex-m architecture layers and the arguments critical for CTOs in the DACH region.
| Architecture Layer | Tool | Measurable Rationale |
|---|---|---|
| Database | Neon PostgreSQL | Serverless architecture with the ability to instantly create branches for CI/CD tests. Full GDPR compliance (instances exclusively in Frankfurt). |
| UI Interface | Svelte 5 (Runes) | Zero Virtual DOM overhead. Minimal JavaScript bundle size, crucial for data manipulation in catalogs with 5000+ SKUs. |
| AI Backend | Python + Vertex AI | Complete abandonment of no-code tools in favor of proprietary orchestration. Precise fusion of vector data to prevent Attention Drift. |
| ORM | Drizzle | Type safety and ultra-lightweight data access, eliminating the overhead of older libraries (e.g., Prisma). |
Model Context Protocol (Linux Foundation) is the de facto interface between agents and tools. Build integration once — works with Gemini, Claude, GPT, and Copilot. nex-m methodology: Python + MCP layer, no single-model lock-in.
Product discovery shifts from search engines to AI agents. Product data must be structured, machine-readable, and real-time. Headless PIM as SSOT is a prerequisite for Answer Engine Optimization.
EU regulation requires lifecycle tracking — composition, origin, sustainability. PIM becomes a compliance hub, not just a description store. Data architecture must be audit-ready.
