Developer infrastructure teams are choosing from a crowded set of agent frameworks, AI gateways, observability platforms, feature flag systems, internal-tool builders, testing tools, and developer portals. This June 2026 section uses the supplied ToolVitals data for Developer Infrastructure Tools, including rank, ToolVitals score, health score, shipping score, GitHub stars, openness_label, license_label, pricing_scope, and status.

The ranking is limited to open/source-visible tools and is ordered by ToolVitals score first, with GitHub stars used as the secondary popularity signal when scores tie. That means the top group is dominated by tools with perfect or near-perfect ToolVitals scores, while star count separates projects with the same score rather than overriding health or shipping signals.
