Rust server hosting is here

You can now create a vanilla Rust server on Crafty Servers. Choose 12 GB RAM or more for a persistent world with console access, file management and SFTP.

The preset uses a 3000-size procedural map. First installation and map generation can take several minutes. Game and query ports are assigned automatically, and every server gets a unique RCON password. Rust+ is disabled.

This option is for new PC Rust servers. Existing servers and worlds are unchanged. See Rust hosting and start a server.

Launch validation: Steam dedicated-server build 25902425 on the public branch passed installation, a ten-minute stability test, public server queries and a save/restart check.
