How we rank & score

The best Design & prototyping

Every option ranked — open-source, self-hostable, and commercial — by our transparent Sovereignty Score, with honest trade-offs so you choose what fits you, not us.

Interface design, prototyping and diagramming. Priced per editor per month, which is how a design team of six becomes a four-figure annual line.
