Performance & AI
Modify nothing. Extend everything.
Core is a light dependency
A versioned npm package you install, never fork. Overlays replace behavior at build time so you can always update without fear.
Extend everything
Overrides live in your layer, not the core. Replace modules and workflows safely. The foundation stays intact.
Your agents write code
Specs ship with the repo from day one. Agents write architecture-aware code. Changes stay consistent and safe.

Case Studies
Air&Ocean Logistics ERP
FreightTech.org built a fully owned logistics ERP on Open Mercato in 6 weeks — covering CRM with automated quote handling, estimated vs. actual cost control, and live Track & Trace integration with major shipping lines and AIS vessel positioning data. One platform for the full operational cycle. No license fees, no lock-in. A secure portal where DBAs can't read PII: per-tenant encryption, field-level AES-GCM and a full audit trail — ready for regulated environments.
