Frequently asked questions
How do you keep these comparisons honest?
Each page names the competitor's genuine strengths and only claims what Diagrams.so actually does today. Plans are metered — Free gives 10 credits that never reset, Pro 75 per month, Power 250 per month — diagrams export as native .drawio, and anything we cannot stand behind is left out.
Which alternative should I pick?
It depends on the job. Some tools are better for live cloud scans or cost views, some for diagrams-as-code in git, some for team whiteboarding. Every comparison page ends with a plain "ideal for" recommendation that says when the other tool is the better choice, not just when Diagrams.so is.
Can I import my diagrams from another tool?
If it is a .drawio file, yes — importing .drawio is free on every plan. Proprietary formats such as Lucidchart, Miro, Eraser, and Whimsical cannot be imported directly; you describe the same system in plain English and regenerate it as an editable .drawio.
What is the free way to try Diagrams.so before switching?
The free tier gives you 10 credits with no credit card. That is enough to generate a few diagrams, export .drawio, and compare the output against your current tool before you decide.
Do you compare on price?
Where it is relevant. Diagrams.so is $0 / $15 / $25 per month, billed per account with usage metered in credits, while many alternatives price per seat. Each page lists the honest pricing shape so you can weigh it for your team size.
