Libre/Starter/Premium/Ultimate are the names of plans for our distributions. CE and EE are distributions of GitLab. CE has _only_ FOSS code in it for users (e.g. self-hosting open source projects) who don’t want to run any proprietary code whatsoever. Libre features are any features that are in the CE distribution by default.

The Free/Bronze/Silver/Gold plans are for GitLab.com specifically (all open source projects get Gold features by default).
