Use your computer from anywhere, at full quality, for free.
Both sides need Tailscale, logged into the same account. That is what lets them find each other on any wifi. Apollo sends the screen, Moonlight shows it.
Open this page on the computer you want to reach, download the app, and choose “This PC stays at home”. It installs Apollo and Tailscale, stops the machine from falling asleep, makes closing the lid harmless, and pins streaming to the graphics card. Then it asks you to make up an Apollo password and shows you the address for your phone.
It opens straight away without asking for administrator rights. It only asks when it actually installs something.
From then on it is one tap in Moonlight. Test it once on mobile data before you travel: if it works there, it works anywhere.
Only Tailscale has an account. Every device logged into your account forms your own private network and can see the others. Apollo and Moonlight have no accounts at all.
They get their own separate private network. They control their own computer from their own phone. They cannot see your machines and you cannot see theirs. Nothing is shared by accident, so handing the app to a friend is safe.
Two ways. Either add them to your network as a user (the free plan covers up to 6 people), or better, use Tailscale's Share feature on just that one machine. Sharing is free, they keep their own account, and they get access to that machine only, nothing else of yours.
No, there is a second lock. Even someone on your network still has to pair with a PIN typed on your computer before Apollo will stream anything. No PIN, no picture.
No. A sleeping computer cannot be woken reliably over wifi, so EASY REMOTE turns sleep off on the home machine. The screen can still go dark, that costs almost nothing.
