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. This June 2026 section uses the supplied ToolVitals dataset, including ToolVitals score, health score, shipping score, GitHub stars, status, openness_label, license_label, and pricing scope for each ranked tool.
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.
