INDI Library is the standard astronomical equipment driver for Linux and macOS.

You can install INDI with the packages provided by your Linux distribution, but as this is a rapidly moving project it is best to get the latest version directly from the project.
For example for Debian/Ubuntu see https://launchpad.net/~mutlaqja/+archive/ubuntu/ppa
It is also easy to build INDI from source. You can get the script I use myself:build_indi.sh. Be sure to install the prerequisites and add the drivers you need in the setup section at the beginning of the script.

INDIWebManager and INDIStarter distribution include the INDI server and the drivers.

Install INDIWebManager from: https://github.com/rlancaste/INDIWebManagerApp/releases
or
Install INDIStarter from: https://sourceforge.net/projects/indistarter/files/

There is no INDI server for Windows but you can run CCDciel on Windows to connect to a INDI server running on a remote computer, a Raspberry Pi for example.

You can use IndiStarter to help to manage the INDI server and the drivers.
Download for Linux and macOS are available from https://sourceforge.net/projects/indistarter/files/

If you use a EQmod mount it can be useful to install EQmodGUI to easily control the main options. This also give you a virtual handpad to move the mount.
Download for Linux and macOS are available from https://sourceforge.net/projects/eqmodgui/files/

The Indigo server variant may work by using the INDI protocol compatibility but is untested.
