This new year GitHub is Announcing the unlimited free private repository and unified Enterprise offering for everyone. This will increase user base of Github and daily commits. Now GitHub more accessible to developers: unlimited free private repositories, and a simpler, unified Enterprise offering.
At the end of December 2018, 31 million developers in the GitHub community building our collective future and developing software.
GitHub Free now includes unlimited private repositories. For the first time, developers can use GitHub for their private projects with up to three collaborators per repository for free. Many developers want to use private repos to apply for a job, work on a side project, or try something out in private before releasing it publicly. Starting today, those scenarios, and many more, are possible on GitHub at no cost. Public repositories are still free (of course—no changes there) and include unlimited collaborators.
GitHub Enterprise is the new unified product for Enterprise Cloud (formerly GitHub Business Cloud) and Enterprise Server (formerly GitHub Enterprise). Organizations that want the flexibility to use GitHub in a cloud or self-hosted configuration can now access both at one per-seat price. And with GitHub Connect, these products can be securely linked, providing a hybrid option so developers can work seamlessly across both environments.
