I’ve been using this website for a while now: https://dlpsgame.com/category/ps4/

Though I’ve mainly use it for PS3 DLCs

Always use an adblocker. With ublock, no issues at all.

Right now I’m using InstaPro. It’s receiving frequent updates and as for now, I don’t have any major complaints about it.

If you want to download it, its official website is instamod.net. Watch out for fake links you may find on Google.

You can use Parsec. It’s free and closed source, but it has an optional driver that, if you install it (you will be asked during the main installation) it will allow you to use Windows in remote without an attached screen. I tried it and it worked quite well. In the remote device you can even select at what resolution you want your host computer to cast when there is no screen plugged in…
