screego is described as 'For developers, screen sharing shouldn’t be optimized for low bandwidth or presenting some slides. It should be high definition, that you still can read the tiny font of your colleague. No more, “wait a minute, the stream isn’t updating”' and is an app in the Remote Work & Education category. There are more than 10 alternatives to screego for a variety of platforms, including Mac, Linux, Windows, Android and iPhone. The best alternative is TeamViewer. It's not free, so if you're looking for a free alternative, you could try Chrome Remote Desktop or DWService. Other great apps like screego are AnyDesk (Paid), UltraVNC (Free, Open Source), X2Go (Free, Open Source) and Apache Guacamole (Free, Open Source).
DWService is an open source project which offers a service that allows access to remote systems (Windows, Mac, Linux, Raspberry...) using a standard web browser - without any component required on the client side.
UltraVNC is easy to use and free software that can display the screen of another computer (via the Internet or a local network) on your own screen. The program allows you to use your mouse and keyboard to control the other computer remotely.
X2Go is an open source remote desktop software for Linux that uses the NX technology protocol. X2Go can be used to access PC desktops, but its main use case is providing secure standalone remote sessions via ssh.
Apple Remote Desktop is the best way to manage the Mac computers on your network. Distribute software, provide real-time online help to end users, create detailed software and hardware reports, and automate routine management tasks — all without leaving your desk.
