The original
Apollo
A Sunshine fork for self-hosted game and desktop streaming at the client device's native resolution.
Replacements
Listings that take over the same core job as Apollo.
Sunshine
The open source host that replaced NVIDIA GameStream, so Moonlight can stream from any PC.
Sunshine is the upstream host Apollo builds on, with Windows, Linux, macOS and FreeBSD support and a web interface, but without Apollo's native-resolution and virtual display features.
Parsec
A low-latency remote desktop app for reaching a work or gaming computer from another device.
Parsec is a proprietary freemium app for Windows and macOS with its own client and 4K 60 fps streaming, instead of a self-hosted host without a vendor account.
