nextcloud
A self-hosted, open-source platform for file sync, sharing, and collaboration with calendar, contacts, mail, and video chat apps.
What is nextcloud?
Nextcloud Server is an open-source, self-hosted platform that provides file synchronization, sharing, and collaboration tools. It acts as a private cloud solution, allowing users to store and access their data—including files, calendars, contacts, and more—from a server they control. The platform solves the problem of data privacy and vendor lock-in by offering a secure, extensible alternative to commercial cloud services.
Individuals, organizations, and enterprises seeking a private, self-hosted productivity suite with full data control. It's ideal for those who prioritize security, data sovereignty, and avoiding reliance on proprietary cloud providers.
Developers choose Nextcloud for its strong emphasis on security, privacy, and open-source ethos. Its unique selling point is complete data ownership combined with a rich ecosystem of apps, allowing customization without sacrificing functionality compared to commercial alternatives.

Cons
