SunRealms is a free Minecraft server for Java and Bedrock players, offering three custom-coded realms: Gens, Dungeons and Prison. Players can join at web.sunrealms.net and choose the style of play that suits them. In Gens, they build generator empires and compete to increase production. Dungeons focuses on fighting through challenges, improving gear and climbing the ranks, while Prison lets players mine, rank up and work toward breaking out.

The realms share Sunbits, a global currency that can be used across all three and does not expire unless spent. SunRealms also offers store items such as ranks, crates, lootboxes, bundles and Sunbits packs. Ranks are lifetime purchases, while some items, including crates and sellwands, may expire when used or when a season ends. Each realm runs its own seasons, with monthly updates and fresh items; maps reset between seasons.

Players can find server information, rules, voting, guides and updates on the website. Support is available through Discord, and content creators can apply to participate.
