Diagram AI alternatives

Diagram AI turns a plain-language description of a process or system into an editable diagram that you can refine through chat, edit on the canvas, and export as XML, SVG or PNG. When choosing an alternative, weigh whether you need diagram-as-code, real-time team collaboration, API access, document or image import, or a broader project workspace. Pricing and self-hosting details are missing for several options, so check them directly.
