Valve does an insane amount of testing and lists Steam Deck compatibility in its listings.
But it’s essentially as simple as downloading a file and installing it.

Get ProtonDB information right into your Steam Deck library with this simple, yet highly useful plugin.
Tap on this, then tap on the little icon that looks like a shop.
Then just tap onInstall.
What the plugin does is add a ProtonDB rating badge to any game in your library.

The ProtonDB Badges plugin for Steam Deck is available through Decky Loader.
They don’t have to be installed to your Steam Deck, either.
You have a couple of options to customize the look, as well.
It’s a simple touch but a serious quality of life improvement.

That little Gold badge comes directly from ProtonDB and will take you to its listing if you tap on it.
As someone who’s been gaming on Linux for a number of years, ProtonDB is an essential.
This just makes it so much more convenient to use for Steam Deck gaming.

There aren’t many settings, but you can customize how the badges will look.
