Self-host Nextcloud
Self-hosted file sync, sharing, calendar, and collaboration suite — the most complete Dropbox/Drive replacement.
Key facts
Pick Nextcloud when you want one server that replaces Dropbox, Google Calendar, Contacts, and Office behind a single login — and you'll give it 4 GB of RAM, a real database, and the occasional afternoon of upkeep. If you only need files synced, ownCloud or Syncthing is less to run.
Follow the Nextcloud deploy guide →What you need
- Any VPS with at least 1024 MB of RAM
- A domain you control — most self-hosted setups need HTTPS in front of them
- About an afternoon — budget time for troubleshooting

Install with Docker Compose
Save this as compose.yml and run docker compose up -d:
# Nextcloud + MariaDB
services:
db:
image: mariadb:11
environment: { MARIADB_ROOT_PASSWORD: changeme, MARIADB_DATABASE: nextcloud }
app:
image: nextcloud:apache
ports: ["8080:80"]
depends_on: [db]
# docker compose up -d → http://SERVER_IP:8080Two ways to run it
The project's own nextcloud:apache image — you supply the database, Redis, and a reverse proxy. Maximum control, the most pieces to wire up.

Running Nextcloud yourself means owning the three things a SaaS quietly handles for you:
An alternative to
Head-to-head
The PHP collaboration platform vs. the Go file server with no database.
All-in-one platform vs. lean file sync.
The all-in-one platform vs. the focused sync engine.
Peer-to-peer file sync vs. the all-in-one file platform.

Common questions
How much RAM does Nextcloud need?
Nextcloud's manual asks for at least 128 MB per PHP process and recommends 512 MB; our catalog floor is 1 GB for a small instance. Give it more if you turn on resource-heavy apps like full-text search or the built-in office suite for several concurrent users.
Can I self-host Nextcloud with Docker?
Yes — the standard setup pairs the official nextcloud:apache image with a MariaDB container in a docker-compose.yml. Running docker compose up -d brings it up on port 8080.
Is Nextcloud a good Dropbox alternative?
Nextcloud covers Dropbox's core file sync and sharing and adds built-in calendar, contacts, and document editing, all under the AGPL-3.0 license on a server you control.
Is Nextcloud hard to maintain?
It's a mid-difficulty stack (PHP plus a database that needs periodic updates and backups), but the official Docker image keeps day-to-day operation to pulling new image tags and running compose up.
