Is Diagram worth the price?

60/10

This pricing structure is difficult to assess for fairness due to the 'Custom' pricing for the Pro tier.

The Free tier is generous for basic diagramming, but the lack of transparency for advanced features makes it hard to determine value. It's best for individuals or small teams needing basic tools, or larger organizations willing to negotiate for advanced features.
