Choosing an identity and access management tool requires comparing project health, shipping activity, licensing, and practical scope rather than relying on name recognition alone. This September 2026 section uses the supplied current ToolVitals facts for each listed tool, including its rank, ToolVitals score, health score, shipping score, openness label, license label, and GitHub-star context.

The ranking covers open/source-visible tools in the supplied set. Tools are ordered by ToolVitals score descending, with health and shipping used for equal composite scores. GitHub stars are context only and are not used as the ranking basis.
