Open Mercato
Open-source TypeScript framework for building CRM/ERP apps, AI-coding-assistant friendly.
🔗 Visit Open Mercato
Description
Open Mercato is a foundation for building business software — a CRM, an ERP, an order management system — that arrives roughly 80% finished, so a developer starts from working multi-tenancy, permissions, and business modules instead of deciding those architectural questions from a blank file, the way a house-builder starts from a poured foundation instead of raw dirt.
It's an open-source (MIT), TypeScript framework built on Next.js and PostgreSQL, with pre-built modules for sales, orders, catalog and pricing, plus multi-tenancy, role-based access control, and event-driven architecture already decided as conventions. Its distinguishing design choice is being explicitly built for AI coding assistants (Cursor, Claude Code, Codex) via structured specs and MCP support, so an AI agent can extend the app along existing patterns rather than re-deciding architecture each time.
💬 Our review
The short version: Open Mercato is a genuinely useful head start for developers building custom business software with an AI coding assistant, though it's a young framework you're betting future maintenance on.
Most CRM/ERP options are either fully built SaaS products (Salesforce, HubSpot) you customize within their limits, or roll-your-own frameworks with no opinions at all. Open Mercato sits in between: real architectural decisions are pre-made (multi-tenancy, RBAC, modules), but you own and can modify all the code, and it's specifically designed so an AI assistant extending it doesn't have to re-litigate those decisions. At roughly 1.7k GitHub stars it has real traction for a young project, but it's still early — teams should weigh the productivity gain against the risk of building on a framework that hasn't yet been proven across many years of production use the way Django or Rails have.
