The free plan is listed at free and includes local diagrams, SQL dialects, and import and export. In the open-source editor, diagrams and custom templates live in browser IndexedDB, tying them to that browser profile. The maker says it can also be self-hosted with Docker. Pro options add cloud storage and sync, public sharing, AI assistance and version history; team options include workspaces, roles, diagram permissions and live collaboration. The AI assistant can create or edit schema elements from prompts, while the MCP server provides read-only access for compatible coding tools to schemas in Pro cloud workspaces. Schema context is sent to the AI service when it operates on a diagram.
