Splashtop does not currently support linux OS. However, since Splashtop Business does support a "Chrome app", a linux user can use the Chrome Business app to make connections to other computers (Windows/Mac) with the streamer program installed and logged in.
If you need to have remote access into a linux computer, there is an old unsupported alpha/beta build that you can try at your own risk. It only has features for the Personal service.
Due to priorities, there is no near-term schedule for a linux streamer. Please vote on the linux feature request or add a feature request in our Community area:
