Best S&Box Servers 2026

Players decide it, not us. Servers are ordered by the votes they collected this month, and every vote is screened for VPNs, proxies, bots and repeat device fingerprints before it counts, so the order reflects real people. Totals reset on the first of each month, which suits S&Box especially well: game modes here are hobby projects that come and go, and one that empties out drops off the list instead of coasting. Sort by Top Rated to weight player reviews over raw vote volume.

S&Box is Facepunch's newer sandbox platform, built on Source 2 rather than the original Source engine that Garry's Mod runs on. The biggest practical change for players is the code: game modes and addons are written in C# instead of Lua, and content is published as packages through S&Box's own system rather than the Steam Workshop. It looks and behaves like a modern engine, with better lighting, physics and asset tools, but the idea is unchanged, in that the community supplies almost everything you actually play.

Expect the same spread that made Garry's Mod popular, rebuilt from scratch: open sandbox worlds for building and physics experiments, shooters and deathmatch arenas, hide-and-seek or prop-hunt style party modes, horror and co-op projects, racing, and roleplay servers with their own rules. Because each mode is its own C# package, the server you join is effectively a separate game, so read the listing description and the owner's Discord before you commit an evening to it.

Get S&Box itself first, from Facepunch through their own channels, because this site hosts no downloads at all. Once the client is installed, open a listing here and follow the link to the server's website or Discord, then use whatever the owner posts: most modes are started from inside the game by picking the package and joining an open lobby, while some communities publish their own connection details or a session time. Reading the Discord rules first avoids an instant kick on roleplay servers.

Joining any server on this list costs nothing, and the list itself is free to browse and free for owners to list on. Most S&Box game modes are published by their creators rather than sold, so what a server asks for varies: many are hobby projects with no shop at all, some run donation links to cover hosting, and a few sell cosmetic extras. Nothing here is paid placement, so a server sitting at the top bought no advantage; it simply collected more verified votes.

Look at this month's vote count before anything else, because it only covers the current month, so a high number means people were logging in within the last few weeks. Each listing also has a public vote-analytics page showing votes per day and the countries they came from, which tells you when the server's peak hours fall. After that, open the Discord: a mode with recent bug-fix posts and people asking for a lobby is alive, one with a dead announcements channel is not.

Joining is low-risk, because you play through the official client and its package system rather than installing a stranger's executable. The sensible rules still apply: take any extra tool only from the server's own website or Discord, never hand over your Steam login or trust a bot that asks you to verify with it, and treat a server that wants your antivirus switched off as a hard no. The player reviews and Discord activity on each listing are worth two minutes of your time.

You can vote once every 24 hours for each server, and the same account can support several different game modes on the same day. Every vote runs through VPN, proxy, bot and device-fingerprint checks, so a server cannot inflate itself with a rented box full of clicks, and blocked attempts show up on its public analytics page. Counts wipe on the first day of the month. Many owners add a vote-return link that hands you something in-game afterwards, which is entirely their choice.

Yes, and that is the whole point of the platform. Facepunch built S&Box so anyone can write a game mode in C#, publish it as a package and let other people load it, and opening a session for friends happens from inside the client itself. Once it is running and you want players you did not already know, adding it here is free: there is no paid placement, and new entries turn up straight away under the Newest sort.
