Choosing a design or prototyping tool means balancing practical fit with signs that the project is healthy and shipping. This October 2026 snapshot uses current ToolVitals data to surface open/source-visible options and show their scores, health, shipping, openness labels, and licenses.
The ranking covers open/source-visible tools in descending ToolVitals score, with health and shipping breaking ties on equal composite scores. GitHub stars are context about repository attention only and do not determine the ordering.
