Is this a client or a service?
A service. Lumobix Server runs on the PC that's meant to be the server. The client is Lumobix, the app on the PC or laptop you connect from. Both come from Lumobix and are made to work together.
Do I need Lumobix to connect?
No. Every user can also connect with any terminal (ssh user@address) or fetch files with an SFTP program. Lumobix makes it more convenient: click the server from your account, and it sets up the key and fingerprint by itself.
Does my data go through Lumobix?
No. The connection always goes directly to Lumobix Server. It only talks to Lumobix for the account. There it stores its address so that Lumobix can find it on the go. Only the owner can see this address.
Does the PC have to be on all the time?
Yes, it's the server after all. The service keeps it awake; the screen can be off. If you stop the service in the app, the PC can go to sleep again.
Does it also run on Linux or Mac?
Lumobix Server is currently available for Windows 10 and 11. You can connect from Windows, from a Mac and from any device with a terminal.
