SilverSteam (v2) is a successor of DarkSteam, but unlike it it's not aimed at downloading game files, although some meta data can be downloaded, indeed. This is more about an alternative way to provide Steam Library content. While there is SteamDB service, it's more for tech guys, rather than general users and Steam itself may seem a bit cluttered some times or in need of addons like EhancedSteam. This is a try to find a middle ground.
