Free Tier Value
This free tier is a capped but genuinely usable starter offering: it lets a user create and edit diagrams, but limits storage/sharing to 3 diagrams and keeps the export set basic. With no paid price shown on the page, a conservative buyer-side estimate is about $2/month for the practical value of a small, perpetual free workspace with API/MCP access and no stated credit-card requirement.
