OwnCloud Infinite Scale vs Nextcloud: Which file server should you choose?
A practical guide comparing two open-source file platforms. Performance benchmarks, feature breakdown, pricing, and the real cost of switching. Pick the one that fits your workflow.
You're evaluating two solid platforms
Nextcloud is the comprehensive suite: files, calendar, mail, video conferencing (Talk), office editing, and AI. 37,000 GitHub stars. Proven. Mature ecosystem with 400+ community apps.
OwnCloud Infinite Scale (oCIS) is the lean alternative: fast file sync and share, written in Go, deployed as a single binary. Smaller community (2,100 stars), but it's where ownCloud Inc. is moving for performance-critical deployments.
Both are open-source. Both support WebDAV. Both store files as files, not proprietary blobs. The choice is not about lock-in—it's about what you need to run and how much you want to tune it yourself.
The performance gap is real
A 2026 benchmark test (Hetzner CX31, 4 vCPU, 8GB RAM, Postgres + Redis) measured both platforms under realistic load with 12 concurrent users over 30 minutes.
Throughput: oCIS achieved 71.3 requests per second. Nextcloud achieved 46.8 req/s. oCIS is 52% faster.
Latency: oCIS median response time (p50) was 97 milliseconds. Nextcloud was 183ms.
Memory: oCIS idles at 420MB RAM. Nextcloud idles at 1.8GB. Under peak load, oCIS used 1.6GB vs Nextcloud's 4.2GB.
File upload: A 4GB photo upload took 8 minutes 15 seconds on oCIS, 11 minutes 40 seconds on Nextcloud.
The catch: Nextcloud can match oCIS performance—but only with expert tuning (Redis configuration, connection pooling, PHP-FPM worker counts). oCIS performs well out of the box.
At scale: When you reach 10,000+ concurrent users, oCIS's microservices architecture lets each component scale independently. Nextcloud requires aggressive database optimization and caching strategy. The complexity grows.
What each platform includes, and doesn't
Nextcloud is a kitchen sink. Files, calendar (CalDAV), contacts (CardDAV), mail, tasks, notes, video conferencing (Talk with screen sharing and SIP support), collaborative office editing, and an AI assistant that runs locally or integrates with external APIs. 400+ community apps extend it further. One login. One place to look.
oCIS is a scalpel. File sync and share only. Calendar, mail, chat, and video conferencing are deliberately not built-in. You bring your own tools (Outlook, Zoom, Mattermost, Radicale, SoGo) or integrate them separately. Fewer features, fewer dependencies, easier to maintain.
For teams replacing Google Workspace, Nextcloud is the faster decision—everything you need in one place.
For teams who already use Outlook, Zoom, and Mattermost, oCIS is the simpler choice—a fast file backbone, nothing more.
Licensing: Nextcloud is AGPL v3 (no feature gates; all code is open). oCIS is Apache 2.0 (more permissive; some enterprise features are paywall-gated). If you're embedding either into a commercial product, oCIS's license is more business-friendly.
Why the implementation matters
Nextcloud runs on PHP + Symfony. You need Apache or Nginx, MySQL or Postgres, and Redis for caching. More moving parts. More to configure. More failure points. A simple deployment has 5+ services running.
oCIS is written in Go and deploys as a single binary. No PHP daemon to babysit. No separate database service (can use embedded SQLite or external Postgres). You can run it on a Raspberry Pi.
Storage is pluggable in both: local disk, S3-compatible object storage, WebDAV, network shares. Both support external authentication (LDAP, OIDC, Keycloak).
What this means for you:
- Small setups: oCIS idles at 420MB. Nextcloud idles at 1.8GB. Budget matters.
- Large setups: oCIS scales horizontally; Nextcloud requires careful database tuning and Redis optimization.
- Operations teams: oCIS is simpler to deploy and monitor. Nextcloud needs more specialized ops knowledge.
What it costs to switch between platforms
Files are portable via WebDAV. Metadata is not.
If you migrate from Nextcloud to oCIS (or vice versa):
- Files: Portable via WebDAV. No data loss.
- User accounts, permissions, group memberships: Rebuild manually. No automated migration.
- Calendar events, mail folders, chat history, settings: Stuck in the old system.
Real migration plan: Run both servers in parallel for 1-2 weeks. Reconfigure sync clients on every device (desktop, mobile). Verify nothing was lost. Budget 1-2 weeks of operational work for a 50-person team.
The good news: Both platforms support WebDAV. You can extract files to Nextcloud, oCIS, Seafile, Synology, or any WebDAV-compatible service. You are not trapped.
The bad news: The switching cost is in operations time, not dollars. So the platform you pick today will probably stay your platform.
Choose based on your needs for 3-5 years, not on price or reversibility.
If you don't want to operate it yourself
Both platforms have managed hosting options. Pricing is nearly identical.
Nextcloud One (Germany-based): EUR 13-15/user/month for teams 5+. 30-day free trial. 24/7 support. 30-day deleted file recovery. GDPR-compliant German hosting.
ownCloud.online (Germany-based): EUR 13-15/user/month for teams 5+. 14-day free trial. 24/7 support. 180-day deleted file recovery (better for accidental deletions). GDPR-compliant German hosting. Optional Cloud Office add-on for EUR 4/user/month.
Pricing parity means the decision is feature fit, not cost. Choose Nextcloud One if you want all-in-one (calendar, mail, video included). Choose ownCloud.online if you want lean (file sync only, bring your own tools).
Opsily also offers managed Nextcloud hosting at comparable pricing, often with better support responsiveness and more granular control over your instance configuration.
Why Opsily's managed hosting removes the complexity
