About ProtonDB for Steam

ProtonDB for Steam adds proton badges to the Steam game pages. This way, you know how well a game runs on Linux before you actually buy it. The extensions shows you the proton rating, if available, and also if a game has a native Linux version alongside it. The project is open-source and can be found on GitHub. Credits to MostwantedRBX on GitHub for founding the project Version 1.6.4 Changelog: - Added the ability to toggle badges in a new settings page - Added the ability to change badge colors in the settings page - Added steamdeck verification badges - Fixed some broken features Coming Soon: - Badges on the front page
