Are you looking for alternative to GSuite from Google ?
You can use Only Office. It has several features that also available at GSuite. They are :
- Online editor
- Document management
Few of them are paid and few others are available in community edition (which is free to download).
The server (core/base server?) it self, document, and mail server area available for free. These server can be installed on Linux or Docker platform.
Other Only Office tool that also available for free is Desktop Editors. This tool supports more wide-range platform, including Windows and MacOS. Still need other? The portable version is there. But, only Linux user can use it.
The bad news is all of them are only available for 64 bit platform only. Except Windows Vista that is also supported in 32 bit.
You have to try.
Poor me 😦
