Infrastructure as code tools now cover several distinct jobs, from provisioning resources to orchestrating environments and managing cloud-native systems. This July 2026 comparison uses ToolVitals health, shipping, openness, license, and GitHub data to show which source-visible projects appear strongest.
The ranking includes only open or source-visible tools and orders them by ToolVitals score, with GitHub stars used as the secondary popularity signal. OpenTofu, Pulumi, and Meshery each score 100, so their supplied GitHub star counts determine the order.
