Platform Architecture

OpenDart applications are built on a three-layer architecture with NocoDB as the central data hub.

How Data Flows​

PathProtocolPurpose
Flutter → NocoDBREST APIRead/write data, auth, queries
Flutter → n8nWebhookTrigger workflows from UI
n8n → NocoDBREST APIAutomated data operations
AI Agents → NocoDBMCPSemantic database access

Why This Stack​

  • NocoDB provides a REST API automatically for every table — no backend code needed
  • n8n handles all async work, integrations, and scheduled jobs
  • Flutter delivers a native experience across mobile and desktop from one codebase
  • MCP gives AI agents direct, structured access to the data layer
