Nextcloud
#10 in Cloud File Sharing & Storage · Rated 4.4
Self-hosted, open-source file sync and share for enterprises
Nextcloud is an open-source, self-hosted collaboration platform that combines Files, Talk, Groupware and Office integration with strong security and audit capabilities. Enterprises can deploy it on their own infrastructure or choose partner-hosted private clouds, enabling full data control and sovereignty. It supports SAML, AD/SSO, data residency, and a broad app ecosystem (ONLYOFFICE, Collabora, etc.). While highly flexible and privacy-friendly, Nextcloud requires internal IT management and a self-hosted deployment model, which suits organizations with strong governance needs and the resources to operate it.
