For August 2026, this section uses the supplied ToolVitals records, including scores, health and shipping indicators, status, descriptions, license labels, and GitHub-star counts.
The list includes only tools labeled OSI-approved OSS and orders them by ToolVitals score from highest to lowest, with health and shipping used for equal composite scores. GitHub stars are context only and do not determine the ranking.
