    This is literally roblox from 2007-2011, except it is open source and self hosted. While there are other old-roblox launchers, this has the most reputation.

    Novetus is an open-source archive of early ROBLOX builds. You can insert rblx files and either try them by yourself or self-host a server to play it with others. If you want an alternative to ROBLOX, like the style of old ROBLOX, and don't like the alternatives on the market, then this is for you.

    This is mainly a revival of old Roblox but it's perfect and very accurate, it has 2007-2011 but has 2013-2015 coming soon, can't wait.
