Nextcloud's open-source community edition is free to self-host, covering core file sync, sharing, collaboration, and a broad app ecosystem. Nextcloud's paid enterprise plans, starting at €1,900 per year for 100 users on the Basic tier, add official support, guaranteed reaction times, and optional integrations like Outlook. The Standard tier (€3,400) includes phone support and custom consulting options, while the Premium tier (€4,900) unlocks 24/7 and on-site support, clustering, and branding. G2 reviewers frequently note that community users rely on forums and documentation, while enterprise customers gain structured SLAs and faster issue resolution unavailable in the free version.
