Open-source Microsoft 365 alternative: Nextcloud

Microsoft 365 is billed monthly, per user, and the cost grows with every colleague you add. For most teams, Nextcloud covers the same needs, run on your own VPS: you pay for the server once, no matter how many people use it.

What Nextcloud replaces

• OneDrive and SharePoint: file storage with desktop and mobile sync, shared folders and share links.
• Outlook (calendar and contacts): shared calendars and a contacts address book, CalDAV/CardDAV compatible.
• Word, Excel, PowerPoint: collaborative document editing right in the browser (via Nextcloud Office).
• Teams (partly): chat, calls and screen sharing through Nextcloud Talk.

Why self-hosted

Your company data stays on your server, in the EU, GDPR compliant. There are no license-imposed user limits, and the cost is predictable: just the VPS price, billed hourly.

Which plan you need

For a small team, a plan with 2 vCPU and 4 GB RAM is a good starting point; add disk as your file volume grows. You can start small and resize anytime.

How to install it

Pick Nextcloud from the one-click app catalog when creating the server. In a few minutes you have a working instance with the access details on the server. Then enable free HTTPS for secure access.
