TeamExtreme Launcher is very well known European offline launcher that supports servers like Play.TeamExtremeMc.com but also all offline / non-premium servers in general.
Before shutting down the server was running on Minecraft version 1.10 and was hosting up to 500 players at the same time. Since TeamExtreme shut down, the only alternative launcher that is working with offline mode and all versions of Minecraft can be found here: ExtremeLauncher
Even supports latest 1.16.1, enjoy
