Top 37 Design & Prototyping Tools — July 2026

Design & Prototyping Tools cover a wide spread of work: interface design, presentations, diagrams, site builders, image tools, whiteboards, vector editing, video editing, and architecture workflows. This July 2026 section uses the supplied ToolVitals data for each tool, including ToolVitals score, health score, shipping score, openness_label, license_label, GitHub stars, and status.

The ranking includes open/source-visible tools only and orders them by ToolVitals score first, with GitHub stars used as a secondary popularity signal when scores are close. The labels are treated conservatively: tools marked OSI-approved OSS are described with that exact openness_label and their listed license_label, without stretching other licensing models into open source.
