Rust servers with a group limit of 2

A duo server sets its published group limit to two. The game enforces the cap when you form a team, so you and one other player are the maximum. Every fight you take is at most two versus two, unless several duos arrive together.

Yes. The filter checks the group limit the server publishes, not its name. A server can call itself duo and still allow four players; that server will not appear here. If a listed server changes its limit, it leaves the list at the next scan.

Every server on Rust Server Now is rescanned every five minutes. Population, rank, wipe dates and settings in the table come from the public server list. Tier is recalculated from the last seven days of player hours, so it moves as the week does.

It varies. The map resets at the monthly force wipe, but blueprint wipes are each owner's choice. Some duo servers wipe blueprints monthly, some never do. Check the server's own page or its Discord before you pick one.
