Our verdict on ProtonDB

ProtonDB is a free web database for evaluating how Windows and native games run on Linux through Valve’s Proton compatibility layer. It is aimed at Linux players, Steam Deck owners, and anyone researching compatibility before purchasing or installing a game. Visitors can browse a Steam catalog covering 32,163 games, review aggregate compatibility ratings, and read reports submitted by users. Those reports can include Proton versions, hardware, Linux distributions, performance observations, and suggested workarounds.

Its strongest value is evidence depth at the individual-game level. A report can connect a result to a specific Proton version, hardware configuration, or distribution, while the aggregate rating provides a quick summary. Steam Deck verified and playable indicators, Chromebook-ready status, and anti-cheat filtering add useful signals when narrowing a search. Because the service is web-based and cloud-deployed, it works as a reference alongside an existing Linux or Steam Deck setup rather than as an installed compatibility utility.

ProtonDB suits buyers who want practical community evidence and troubleshooting ideas before committing to a game. The crowdsourced model means report detail and consistency can vary between titles, so a rating is best read with the underlying reports and workarounds. Its scope is also deliberately narrow: it concentrates on Proton-based Linux gaming and Steam catalog discovery, not compatibility across every operating system or console. Choose it for Linux and Steam Deck research; users seeking a native app or broader platform coverage should look elsewhere.
