Open Mercato

Open Mercato is an AI-engineering foundation framework that ships with hundreds of architectural and domain decisions already encoded as conventions and specifications. Built with modern technologies like Next.js, TypeScript, and PostgreSQL, it provides teams with a strong baseline while maintaining complete flexibility for customization.

The framework includes three core pillars: Security & Infrastructure (multi-tenancy, RBAC, audit trails, AES-256 encryption), Business Logic (CRM, ERP, orders, workflows, catalog management), and Performance & AI (event streaming, search capabilities, Redis caching, AI assistant integration).

Key advantages include:

• Modify nothing, extend everything — The core remains a lightweight npm dependency you never fork, allowing safe updates without breaking changes
• Build-time overlays — Replace behavior and modules in your layer while keeping the foundation intact
• Agent-aware architecture — AI assistants write code that respects your specifications and maintains consistency
• No vendor lock-in — Own your codebase completely with MIT licensing
• Rapid deployment — Launch enterprise products in weeks instead of months

Teams use Open Mercato to escape the traditional infrastructure tax, build regulated systems with field-level encryption, and maintain code ownership while leveraging pre-built patterns for CRM, ERP, and complex workflows.
