When to choose:
  • You need an open-source, AI-native low-code platform to build internal business dashboards, admin panels, and database interfaces with custom AI agents.
  • You want built-in integrations for PostgreSQL, MongoDB, REST APIs, and modern authentication (SSO, OAuth).
When to skip:
  • You only need a headless background workflow execution engine without a frontend UI; Temporal or n8n are better suited.
  • You want to build public customer-facing consumer SaaS frontends from scratch.
