About Diagram Apps

A field guide to 24 diagram apps, sorted by how you draw in them.

Choosing a diagram app usually comes down to a few plain questions: can I draw the way I think, can I use the free version at work, will the export look right in my document, and what does it cost once the whole team needs a seat. This site answers those for every app, side by side.

No maker pays to be listed or ordered. Guides explain each pick with the facts behind it, and anything a maker doesn't state is shown as "Not stated" rather than guessed.
