Overview

Open Mercato is a TypeScript framework on Next.js and PostgreSQL that scaffolds a business back office with modules for customers, catalog, sales, warehouse, portal and workflows. Each generated app ships an AGENTS.md, skills and specs in .ai/specs/ so Claude Code, Codex or Cursor know where new modules belong. Cezar, a separate MIT orchestrator, can run those agent tasks unattended.

Who it is for: Teams building business apps and back offices with AI coding agents

Strengths

  • Scaffolds via npx create-mercato-app with classic, crm, wms and empty presets
  • Ships AGENTS.md and om-* skills that route agents to the right code location
  • Specs in .ai/specs/ drive a plan, approve, implement flow with tests
  • Core is MIT with no per-seat licence; REST API docs served under /backend/docs

Weaknesses

  • Enterprise modules are licensed separately from the MIT core
  • Setup needs Node.js 24, Yarn 4 and Docker; Windows requires WSL2
  • Dev server serves scripts to localhost only, not 127.0.0.1 or other hosts
  • Fresh 0.8.0 apps report typecheck errors in agent_examples until next release

What it needs

  • TypeScript, Claude Code, Codex, Cursor, GitHub Copilot (experimental)
  • Needs Node.js 24, Yarn 4, Docker, PostgreSQL 17 with pgvector, Redis 7, Meilisearch
  • Docker
