How we picked these
We match on what the tool does and how it installs, then order by how widely each project is used. We're not saying these are better or worse than keystone — that depends on what you're building. We're saying they're the projects people reach for in the same situations, and each one has an install command we checked against its documentation.
keystone is developed by its own authors and this page is an independent reference; we are not affiliated with or sponsored by any project listed, and nothing here is a paid placement.
