Nextcloud allowed us to replace many other services from different providers, now we have almost everything in one place.

- simple to setup, configure, update and use - customizable - many apps and themes available - well documented - possible to connect with other services

- many features you expect to work by default are only available after installing 3rd party extensions - encryption can be difficult to setup - some features can be configured only from command line

It was an easy PHP web app to setup that is fairly extensible. It has a large selection of plugins that let you add basically all functionality you’ll need to parallel something like DropBox Enterprise. I have only used the self-hosted version, so I can only speak to that, but so far, it has been fairly stable, running on an 8core 12GB VM with Ubuntu 18.04 (past 6 months) and Ubuntu 14.04 (for the past 3-4 years). Given that it’s self-hosted though, you’ll get no official support, except from the community forums which have been friendly and helpful. The devs are also fairly active there, so you’ll get good answers. It maintains great integration with iOS and desktop devices (can’t speak for Android), and using it together with a SAML setup is quite a breeze. So far, it has scaled to about 150K small files and 1.5TB of storage. It’s built-in authentication system is also quite robust, with support for TOTP and FIDO 2FA via the plugin system. It also maintains solid integration to Collabora Online and OnlyOffice, allowing real-time document editing with multiple users and guests, which has come in handy quite a few times. Great software overall!

Can be a bit difficult to set up initially. You’ll need a solid understanding of SysAdmin basics to even get off the ground, since it’ll rely on you having a properly configured web server. You’ll also need to know how to properly secure both the installation, as well as the database Nextcloud runs on. A compromise to either of those points would cause a security issue.

We use this as an Intranet solution in our church. The most important functions are booking of locals and for filesharing between groups. We also use PicoCMS for the internal communication of news in the organisation. It works as expected but there has been some resistance to change. We plan to set up social login which should facilitate the use. Setting up and keeping your own server is of course an obstacle. You need some computer and server knowledge to keep this running. We use an external VPS-provider for the production server and another for backup. A local NAS-server for testing. This costs us about 7 EUR/month.

Easy to add new users Easy to upload and download files Possibility to read and edit documents also in the phone Possibility to add blogg-pages for intranet with the PicoCMS app Calendar app works very well Sync with laptop and desktop using the desktop client

The e-mail app is rudimentary The coupling between Contacts and E-mail app is incomplete Creating and editing documents and adding photos is possible in the phone but a bit slow The risk for conflicting versions if using desktop client, but this may be soved in version 18 as you can locck the file while editing You sometimes need to specifically check that the files are synced, but this also happens to me with other sync solutions (like Box Sync) The calendar app cannot be "swiped" or "scrolled" to the next week or month in the webb-browser. But this works with other optional calendar apps.

Open source, high level of security and privacy, fully configurable without software restrictions. Great support

Although Nextcloud is well documented and a big community is providing support, setting up Nextcloud from scratch requires some IT skills and knowledge.
