GitHub Actions and Packages are free for public repositories and packages on all our current per-user plans, while private repositories and packages receive a set amount of free minutes, storage, and data transfer depending on the per-user plan. Legacy per-repository plans (Bronze, Silver, Gold etc) do not come with access to GitHub Actions and Packages but they can be upgraded to a current per-user plan.
