We do support plugins, data packs, as well as 3rd party Minecraft Server runtimes such as Spigot, Paper, and Forge. You will need to purchase Standard FTP Access to gain access to the server's files to install any plugins or runtimes. With a support agreement for the server, our support staff can also help in the setup and configuration of any plugins or runtimes. Support agreements entitle you to a White-Glove Onboarding process for your new game server upon request through Discord, live chat, or a Support Ticket.
Note: We do not guarantee the performance of any tier game server when mods are installed, and we highly recommend only installing mods on Large or above sized game servers due to the extra processing power available with the 4+ vCPUs and extra memory overhead added.
