Readers comparing AI agent tools face a broad mix of personal assistants, coding agents, and retrieval systems, making it difficult to distinguish project health from popularity. This September 2026 snapshot uses the supplied ToolVitals scores, health and shipping scores, openness and license labels, and GitHub stars.
The ranking covers open/source-visible tools and orders them by ToolVitals score descending, with health and shipping used for equal composite scores. GitHub stars are context only and do not determine the ranking.
