How Much Of My Steam Library Is Compatible With Steam Deck?

I recently published an easy guide showing you how to track the growing list of Steam Deck “Verified” and “Playable” games. But what if you want more personalized results? Wouldn’t it be cool to cross-reference Valve’s growing list (we’re currently at 520!) with your own Steam library? It’s relatively simple to do thanks to a web app called “CheckMyDeck.”

UPDATE, Feb 23rd 2022: Valve just launched an official tool for checking your library against the Steam Deck compatibility ratings. Read about it here.

Wait, Remind Me What “Deck Verified” Means

A quick point of clarification before we get into it: just because your game isn’t listed in Valve’s Deck Verified program (yet), doesn’t mean it won’t be playable. Steam has an enormous catalog of games, and Valve’s QA testers are qualifying these by hand.

Valve isn’t merely evaluating if games are playable on Linux (which is what powers the Deck). After all, more than 20,000 native Linux games already exist according to SteamDB. And many thousands more Windows-exclusive games run flawlessly on Linux thanks to Valve’s Proton (which also powers the Deck)!

Rather, Valve is evaluating the experience of playing these games on Steam Deck. Is in-game text legible? Does the default graphics preset perform well? Does the game display Steam Deck controller icons? Is every game function available and working? (As an example, Halo: The Master Chief Collection campaigns run great on Linux, but online matchmaking is broken.)

So, what we’re talking about today is discovering how much of your Steam Library runs well on Deck, according to Valve. And that number is going to be a constantly ascending target.

How To Check Your Steam Library Against The Deck Verified List

To discover how much of your Steam Library is Deck Verified, you'll need this number.
To discover how much of your Steam Library is Deck Verified, you’ll need this number.

Redditor Flexxyyy created a straightforward web app that only asks for your SteamID. Then it checks your Steam library against the growing list of Steam Deck Verified and Playable games. The result: hopefully a decent percentage, and a list of every game you own that falls under each category.

Here’s how to do it!

  1. Visit and enter your Steam Profile name. That’s the name listed when viewing your community profile. Mine is “TheGameTechnician” (future Deck owners: feel free to add me) so I entered that into the box.
  2. On the results page, look for the “SteamID64 (Dec)” field. Copy the number that’s there.
  3. Now that you have your SteamID64 number, visit the CheckMyDeck website at
  4. Paste that number into the box and click GO!
  5. Profit?

Hopefully a decent percentage of your Steam library is already deemed “officially playable” on Deck. We’ll all have some games that just aren’t (looking at you, Apex Legends and Lost Ark), at least until game developers switch on EAC and BattlEye anti-cheat support for Proton and Linux. (Valve has worked with anti-cheat developers to make this easier.)

Keep checking every few days and I bet you’ll the number climbing. The data is pulled from SteamDB which is the most current source for all things Steam.

Hopefully you found this guide useful! If you can’t get enough Steam Deck content, check out my dedicated category for Valve’s handheld console. And stay tuned for Episode 3 of Games For Everyone!
