// What it is

A closer look.

Nextcloud is the most comprehensive self-hosted productivity suite — file sync & share, real-time collaborative editing (OnlyOffice / Collabora), calendar, contacts, mail, chat, video calls, password manager, and a 200+ app ecosystem. The most mature open-source alternative to Microsoft 365 and Google Workspace, with first-class GDPR / EU sovereignty positioning.

The Nextcloud Hub is what most "European cloud sovereignty" initiatives end up specifying. It's not flashy — it's the boring, reliable choice that ships every quarter.

  • 200+ official apps — covering virtually every workspace need
  • E2E encryption — for sensitive files + groups
  • Federation — cross-instance file sharing without re-uploading
  • AGPLv3 — with commercial support tiers — clear OSS commitment

// Tips & operations

Run it properly.

Operational guidance from running this in production — what to do before you scale, what to lock down, what surprises people.

// PERFORMANCE
Run cron via systemd timer, not AJAX fallback
the default AJAX cron silently breaks under load and stops background jobs
// SECURITY
Use Redis for file locking
set redis_cache_class in config.php; without it, sync conflicts compound under concurrent users
// OPERATIONS
Pretty URLs require nginx rewrite
straight from the Docker image, several share/index links break; copy the official rewrite block
// RELIABILITY
trusted_domains must list every URL
including www / non-www variants; mismatch yields blank-page errors on first request
// DEPLOYMENT
Run occ files:scan --all after bulk uploads
external storage / SFTP imports don't surface until indexed
// SCALING
Talk needs coTURN
without a TURN server, video calls fail behind strict NAT; ship coTURN alongside Talk
