Choosing a product analytics tool requires more than comparing feature descriptions: readers also need a current view of project health, shipping activity, openness, and licensing. This September 2026 ToolVitals snapshot provides those signals alongside each tool’s description and GitHub star count.
The ranking covers open/source-visible tools and orders them by ToolVitals score descending, using health and shipping for equal composite scores. GitHub stars are included as context only and do not determine the ordering.
