Audience: Self-hosters choosing between Nextcloud and ownCloud


Shared Heritage

Both projects share the same origin. In 2010, Frank Karlitschek started the ownCloud project. In 2016, Karlitschek and key developers forked ownCloud to create Nextcloud, citing concerns about open-source commitment and commercial focus. The split created two distinct philosophies.

Performance & Architecture

Nextcloud Architecture

  • PHP-based (traditional LAMP/LEMP stack)
  • Database: MySQL/MariaDB, PostgreSQL, SQLite
  • Cache: Redis, APCu, Memcached
  • Web server: Apache/Nginx
  • Strength: Mature ecosystem, thousands of apps
  • Weakness: PHP resource usage, scaling limits for 10K+ users

ownCloud Architecture (Classic)

  • PHP-based (same stack as Nextcloud historically)
  • Being phased out in favor of Infinite Scale (oCIS)

ownCloud Infinite Scale (oCIS)

  • Go-based (microservices architecture)
  • Database: Built-in (no external DB needed)
  • Storage: S3-compatible backends
  • Web server: Embedded (no Apache/Nginx needed)
  • Strength: Modern, fast, scalable, container-native
  • Weakness: Newer ecosystem, fewer apps
