Deploy Seafile on Ubuntu with Docker — a high-performance self-hosted file sync and share platform with desktop and mobile clients, file versioning, team libraries, and end-to-end encryption support.
Grab the automated bash script from GitHub to follow along with the video.
wget https://raw.githubusercontent.com/mhmdali94/Docker/main/files/seafile/seafile-ubuntu.sh
chmod +x seafile-ubuntu.sh
sudo bash seafile-ubuntu.sh
The script installs Docker and starts the full Seafile stack: Seafile server, MariaDB database, and Memcached for caching — all pre-configured and ready to use.
wget https://raw.githubusercontent.com/mhmdali94/Docker/main/files/seafile/seafile-ubuntu.sh
chmod +x seafile-ubuntu.sh
sudo bash seafile-ubuntu.sh
Open your browser and navigate to the Seafile web interface:
http://<your-server-ip>:8090

Click 'New Library' to create a workspace (libraries are like Dropbox folders — they sync to desktop clients). Upload files from your browser by dragging and dropping. Install the Seafile desktop client on your computer for automatic background sync with any library.
| Port | Purpose |
|---|---|
| 8090 | Seafile Web UI (Seahub) |
| 8082 | Seafile HTTP file transfer (internal) |
| 3306 | MariaDB — internal only, not exposed |
Seafile is a high-performance, self-hosted file synchronization and sharing platform designed for both individual and team use. Unlike simple file managers, Seafile uses a library-based model (similar to Dropbox) where each library syncs independently to desktop and mobile clients. It stores files in a unique block-based storage format that enables efficient delta sync — only changed blocks are transferred, not entire files. Seafile CE (Community Edition) is fully free and open-source, while the Pro edition adds more features for large organizations.
Seafile outperforms Nextcloud in raw file sync speed due to its purpose-built block-based sync engine. For teams whose primary need is reliable, fast file synchronization with desktop clients and file versioning, Seafile delivers Dropbox-equivalent performance on self-hosted infrastructure. Its end-to-end encrypted libraries mean even the server administrator cannot read protected data — a strong privacy guarantee for sensitive documents. Desktop clients for Windows, macOS, and Linux make it invisible to end users who are accustomed to Dropbox.
Seafile uses port 8090 for the Seahub web interface and port 8082 for internal file transfer (FileServer). Both should be proxied through Nginx Proxy Manager on port 443 — never expose them directly to the internet. MariaDB runs on port 3306 internally and must never be exposed externally. In UFW: allow only 80 and 443 for the reverse proxy, and deny direct access to 8090 and 8082. Configure Seafile's SERVICE_URL and FILE_SERVER_ROOT in the configuration to point to your HTTPS domain for file transfers to work correctly.
Nextcloud is the most feature-complete Seafile alternative with file sync, calendar, contacts, office editing, and hundreds of apps — choose Nextcloud if you need the broader collaboration ecosystem beyond file sync. FileBrowser is a simpler web-based file manager without desktop sync clients. Syncthing is a peer-to-peer file sync tool that syncs directly between devices without a central server — no web UI, no sharing links, but highly decentralized. Owncloud is Seafile's closest competitor with similar file sync focus. For pure high-performance file sync with desktop clients in a self-hosted environment, Seafile's block-based engine typically outperforms Nextcloud.
Don't use Seafile if your team needs built-in document editing (like Collabora or OnlyOffice) — Nextcloud includes these integrations. If you need a simple web file browser without desktop sync, FileBrowser is lighter and simpler. Seafile CE doesn't include enterprise features like LDAP sync, Audit Log, or clustering — use Seafile Pro or Nextcloud if those are required. If your team is already on Google Drive or SharePoint and doesn't need to leave the cloud, the operational overhead of self-hosting Seafile may not be worth it for small teams.
PrismaTechWork provides end-to-end infrastructure services — from initial deployment and security hardening to ongoing monitoring, automated backups, and dedicated support. Whether you need a single-server setup or a multi-site network, our team ensures your infrastructure is built right, secured properly, and maintained reliably.
Seafile is optimized purely for high-performance file sync and share with excellent desktop client performance and file versioning. Nextcloud is a full collaboration suite with files, calendar, contacts, office editing, and hundreds of apps. Seafile is faster for large file sync workloads; Nextcloud is better if you need the broader ecosystem.
Yes. Download the Seafile desktop client for Windows, macOS, or Linux from seafile.com. Log in with your server URL, username, and password. Select which libraries to sync — the client automatically downloads files and uploads changes in the background, just like Dropbox.
Yes. Seafile maintains a full version history for every file. Browse version history, compare versions, and restore any previous version from the web interface or desktop client. Version history is kept by default and you can configure retention duration in the admin settings.
Seafile supports end-to-end encryption for individual libraries. Enable it when creating a library and set a passphrase. The client encrypts files locally before uploading — not even the server administrator can read contents without the passphrase. This is true client-side encryption.
Seafile CE has no hard user limit. Performance depends on server hardware. A 4-core/8GB RAM server comfortably handles 50-100 active users with typical file workloads. For larger deployments (500+ users with heavy sync), Seafile Pro adds clustering and better notification delivery.
Seafile requires MySQL or MariaDB for metadata storage (user accounts, library metadata, file version history). The install script automatically sets up MariaDB and Memcached alongside Seafile. Actual file data is stored in the filesystem in Seafile's object storage format, not in the database.
Yes. Generate a public share link for any file or folder — links can have a password, an expiry date, and download-only or upload permissions. External users download files without logging in. Upload links allow external users to submit files to your server without creating an account.
Install the official Seafile mobile app on Android or iOS. Tap Add Account, enter your Seafile server URL, username, and password. Browse libraries, upload photos, download files, and enable auto camera upload so new photos automatically back up to your Seafile server.
