Developer Infrastructure Tools can be hard to compare because they span agent platforms, observability, backend infrastructure, testing, API clients, CMS frameworks, terminals, and internal-tool builders.
The ranking includes open/source-visible tools only and is ordered by ToolVitals score first, with GitHub stars used as a secondary popularity signal when scores are close or tied. License and openness are treated literally: OSI-approved OSS tools are identified as OSI-approved OSS, and their license_label values are reported exactly as provided.
