OpenCloud, Nextcloud, and ownCloud Compared in 2026 Lab Tests
A recent lab test compared OpenCloud, Nextcloud, and ownCloud Infinite Scale across various metrics, revealing key differences in resource usage and performance.
The study evaluated OpenCloud and Nextcloud alongside ownCloud Infinite Scale, highlighting architectural differences: OpenCloud and ownCloud share a Go codebase, while Nextcloud relies on PHP and requires additional components like MariaDB and Redis. These differences significantly impact resource consumption, upgrade processes, and file storage methods.
Benchmark results showed Nextcloud consumes considerably more idle memory and disk space compared to the Go-based servers. While Nextcloudâs CPU usage varied due to internal services, OpenCloud demonstrated faster small-file uploads, although ownCloud exhibited inconsistent performance with occasional retries.
The test recommends OpenCloud for users prioritizing a lean file server, Nextcloud for those needing a comprehensive groupware suite, and advises ownCloud users to plan a migration to Infinite Scale or Nextcloud, particularly given the impending end-of-life for ownCloud Classic in January 2027.
