Languages & package managers
Veln’s agent is focused on dependency flows your teams already use. Today that means JavaScript and Python packaging, with lockfiles and registry behavior the CLI understands.
JavaScript
npm, pnpm, and yarn workflows are in scope: lockfiles, install graphs, and (with gate) npm registry traffic when you configure it.
Python
uv and poetry (and compatible lockfile layouts) are the supported Python surfaces for verify and related flows. Gate can target PyPI as upstream when you use the PyPI enforcement path.
Other ecosystems
Other language registries are not the product’s default focus unless a release explicitly adds them. Check release notes and veln help for your version for the exact matrix.
