 The [ENLIVEN project](https://github.com/expertmm/EnlivenMinetest) (aka EnlivenMinetest) includes tools for installing and maintaining the server and client for internet and LAN use, and now includes the mtanalyze (formerly minetest-chunkymap) project which includes many tools including chunkymap. The server and client are just the Minetest server and client repackaged (or just web installer scripts in the case of the server), and therefore 100% compatible with other copies of Minetest server and client of the same version--including using other subgames, which client will download from servers as usual.
