## Server

For best performance, stability and functionality we have documented some recommendations for running a Nextcloud server.

Note

If you plan a setup for your organization and you rely on professional deployment consulting (e.g. efficient and reliable scaling) and support, we strongly recommend you to check out our enterprise support.

Platform | Options
--- | ---
Operating System | Ubuntu 18.04 LTS (recommended) Red Hat Enterprise Linux 7 (recommended) Debian 8 (Jessie), 9 (Stretch) SUSE Linux Enterprise Server 11 with SP3 & 12 openSUSE Leap 42.1+ CentOS 7
Database | MySQL or MariaDB 5.5+ (recommended) Oracle Database 11g (only as part of an enterprise subscription) PostgreSQL 9.5/9.6/10 SQLite (only recommended for testing and minimal-instances)
Webserver | Apache 2.4 with `mod_php` or `php-fpm` (recommended) nginx with `php-fpm`
PHP Runtime | 7.1 7.2 (recommended) 7.3 (recommended)

See Installation on Linux for minimum PHP-modules and additional software for installing Nextcloud.

### Memory

Memory requirements for running a Nextcloud server are greatly variable, depending on the numbers of users, apps, files and volume of server activity.

Nextcloud needs a minimum of 128MB RAM, and we recommend a minimum of 512MB.

### Database requirements for MySQL / MariaDB

The following is currently required if you’re running Nextcloud together with a MySQL / MariaDB database:

- InnoDB storage engine (MyISAM is not supported)
- “READ COMMITED” transaction isolation level (See: Database “READ COMMITTED” transaction isolation level)
- Disabled or BINLOG_FORMAT = ROW configured Binary Logging (See: https://dev.mysql.com/doc/refman/5.7/en/binary-log-formats.html)
- For Emoji (UTF8 4-byte) support see Enabling MySQL 4-byte support

## Desktop client

We strongly recommend using the latest version of your operating system to get the full and most stable experience out of our clients.

- Windows 7+
- macOS Lion (10.7)+ (64-bit only)
- Linux (CentOS 6.5+, Ubuntu 14.04+, Fedora 21+, openSUSE 13, SUSE Linux Enterprise 11 SP3+, Debian 8 (Jessie)+, Red Hat Enterprise Linux 7)

## Mobile apps

We strongly recommend using the latest version of your mobile operating system to get the full and most stable experience out of our mobile apps.

- iOS 10.x+
- Android 4.x+

Note

The separate Nextcloud Talk app requires iOS 10.x+ or Android 5.x+.

## Web browser

For the best experience with the Nextcloud web interface, we recommend that you use the latest and supported version of a browser from this list, or one based on those:

- Microsoft Internet Explorer 11 (latest version)
- Microsoft Edge
- Mozilla Firefox
- Google Chrome/Chromium
- Apple Safari

Note

If you want to use Nextcloud Talk you should use Mozilla Firefox 52+ or Google Chrome/Chromium 49+ to have the full experience with video calls and screensharing. Google Chrome/Chromium requires a additional plugin for screensharing.
