Choosing Design & Prototyping Tools is awkward because the category mixes UI design editors, whiteboards, website builders, diagramming tools, presentation generators, image editors, and video tools.
The ranking includes open/source-visible tools only and sorts first by ToolVitals score, then uses GitHub stars as a secondary popularity signal when scores are close. GitHub stars help show adoption, but they do not override health and shipping signals; for example, highly starred tools can still rank lower when their shipping score is weaker.

Top 3 Highlights
Penpot ranks first with a ToolVitals score of 100, health score of 100, and shipping score of 100. It is listed as OSI-approved OSS under MPL-2.0, has 49,547 GitHub stars, and is the top dedicated design and prototyping platform in this dataset.
Presenton ranks second with a ToolVitals score of 97, backed by a 95 health score and 98 shipping score. It is OSI-approved OSS under Apache-2.0 and has 8,090 GitHub stars, making it one of the strongest AI presentation tools in the open/source-visible set.
Pascal ranks third with a ToolVitals score of 95, a 98 shipping score, and 16,663 GitHub stars. Its focus is narrower than a general UI editor, but the data shows strong shipping activity for 3D architectural project creation, with OSI-approved OSS licensing under MIT.
