Top 48 Design & Prototyping Tools — May 2026

Design & Prototyping Tools in May 2026 cover a wide spread of work: website builders, vector editors, whiteboards, presentation generators, icon systems, 3D architectural tools, motion graphics, form builders, and visual development tools. ToolVitals compares the supplied tool records using health score, shipping score, GitHub stars, overall ToolVitals score, and status so readers can quickly separate active, high-scoring projects from tools that may need closer review.

The ranking is sorted by ToolVitals score first, with GitHub stars used as the secondary popularity signal when scores are tied. That means Framer ranks first with the only 97 score, while Penpot, tldraw, Webstudio, and Presenton all score 94 and are ordered by GitHub stars within that tied group.
