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.

Hidden Costs & Gotchas

Pro tier price is undisclosed

Potential minimum seat requirements for Pro

Overage fees for advanced features

Integration costs for specific platforms

How Diagram Compares to Competitors

Compared to Lucidchart, which offers a free tier and paid plans starting around $7.89/month, Diagram's 'Custom' Pro tier lacks transparency. Figma, another design tool, has a free tier and paid plans starting at $12/editor/month, making Diagram's advanced features potentially more expensive or requiring negotiation.
