Both OwnCloud and NextCloud are the two main cloud platforms. They both are open source.
Let us examine which one suits you best:
Both solutions are scalable and can handle large numbers of users and files. NextCloud, however, offers better scalability for complex deployments.
The NextCloud has a modern and user-friendly interface when compared to OwnCloud. This makes it easier to use and navigate it.
NextCloud provides more customization options and third party apps. This allows users to use the platform according to their needs.
NextCloud has a vibrant, active community and extensive documentation. OwnCloud also has good support but is more commercially focused.
NextCloud is ideal for collaborative environments, schools, and community projects. OwnCloud is good for business that need stable and enterprise-ready solution.
