Nextcloud

App in the BluixApps catalog

What it is

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.

What it's for

  • Replace Dropbox / OneDrive / Google Drive — desktop + mobile sync, encrypted-at-rest file storage
  • Replace Google Docs / Office 365 — real-time collaborative editing on docs, spreadsheets, presentations
  • Replace Google Calendar / Contacts — CalDAV / CardDAV for any client
  • Replace Slack / Zoom for small teams — Nextcloud Talk for chat + video
  • Privacy-compliant file collaboration — healthcare, legal, government, education
  • Multi-tenant agency offering — resellers branding Nextcloud as their own "cloud workspace"

Who it's for

  • European public sector / government bodies under data sovereignty mandates (BWI, French state IT, Italian PA agencies)
  • Schools & universities under GDPR / FERPA for student data — files and collaboration on owned infrastructure
  • Healthcare & legal firms requiring on-prem document collaboration with full audit trail
  • Privacy-conscious SMBs replacing Microsoft 365 / Google Workspace at predictable per-month VPS cost
  • Agencies offering white-label "branded cloud workspace" to clients as a higher-margin SKU

Why teams pick Nextcloud over alternatives

  • Most mature self-host workspace — 14+ years of development, multi-petabyte deployments in production
  • 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
  • EU-grade compliance — used by German, French, Dutch government bodies; cited in EU sovereignty roadmaps

Integrations

  • Document editors — Collabora Online + OnlyOffice for real-time co-editing
  • Calendar / contacts — CalDAV / CardDAV (Apple, Thunderbird, Outlook, mobile native clients)
  • Desktop / mobile sync — official clients for Windows, macOS, Linux, iOS, Android
  • Identity — LDAP / SAML / OAuth (Authelia, Authentik, Keycloak), SSO via reverse proxy
  • External storage — S3-compatible, WebDAV, SMB, FTP backends for primary or auxiliary storage
  • Chat / video — Nextcloud Talk with coTURN for WebRTC behind NAT
  • App ecosystem — 200+ apps in the official store (mail, deck, forms, polls, password manager, AI assistant)

Notable users & community

  • 30k+ GitHub stars (Server only — the org has many repos)
  • Production deployments: German federal IT (BWI, Bundeswehr), French state IT, Italian PA agencies, CERN, universities worldwide
  • Bi-annual Nextcloud Conference; active forum, weekly developer calls
  • Backed by Nextcloud GmbH (Germany) — strong European OSS company with verified sovereignty references

Tips & operations

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

What we ship in BluixApps

  • Docker compose: Nextcloud (apache variant) + MariaDB + Redis + cron
  • Pinned nextcloud:30.0.4-apache, monthly upstream tracking
  • HTTPS via Let's Encrypt — WebDAV / CalDAV / CardDAV endpoints all correctly proxied
  • Storage volume at /var/www/html/data — sized per VPS allocation
  • Admin user with random password + suggested follow-up apps (Talk, Calendar, Contacts) listed in install report
  • Optional Collabora Online container for document editing (Enterprise tier — RAM intensive)
  • Backup hook covers MariaDB + the data volume (files — opt-in due to size)
