Runtime library choices can create long-lived maintenance risk because they sit close to application code and are expensive to swap later.
The ranking includes open/source-visible tools only and orders them by ToolVitals score first, with GitHub stars used as a secondary popularity signal for ties. Every listed tool here is labeled OSI-approved OSS, with license_label values shown as supplied.
