What Is a Dedicated Server? (Game Servers Explained, 2026)

A dedicated server is a separate program that runs a multiplayer game's world, rules and saves without anyone playing on it, so every player, including the owner, connects to it like a guest. Because it does not depend on a player's game being open, the world stays online 24/7 and performance does not hinge on one person's PC.

That is the short version. Below is what actually happens inside one, the two different things people mean by the phrase, and how to tell whether your group needs one. If you want the head to head with co-op hosting, read dedicated server vs peer to peer first. This page is about the server itself.

What does "dedicated server" mean?

The phrase gets used for two different things, and mixing them up causes a lot of confusion.

When a game says "supports dedicated servers", it means the first one: a server program you can run on any machine. It does not mean you need to rent an entire computer. A single physical box in a data center usually runs many dedicated game servers side by side, each with its own reserved memory.

How a dedicated game server works

A dedicated server is the game with everything visual removed. No graphics, no sound, no menus. What is left is the simulation:

1. It loads the world from save files on disk.
2. It listens on a network port, usually UDP, for players to connect.
3. It runs the game loop a fixed number of times per second. Each loop moves creatures, grows crops, checks hits and applies rules. That rate is the tick rate.
4. It sends updates to every connected player about what changed.
5. It saves the world on a timer and when it shuts down.

Your game client does the drawing. The server decides what is true. That split is why a dedicated server can run on a machine with no graphics card at all, and why it is the authority on who hit whom.

Because there is no window, you control it through a console: a text input where you type commands like save, kick <name> or whitelist add <name>, plus config files for settings that are read at startup.

Where do dedicated servers come from?

Almost every game that takes multiplayer seriously gives its server away for free. On Steam most of them are separate apps you download with SteamCMD, Valve's command line downloader:

steamcmd +force_install_dir ./valheim +login anonymous +app_update 896660 validate +quit

Games outside Steam do it their own way. Minecraft Java's server is a single .jar file from minecraft.net, Bedrock has its own Bedrock Dedicated Server download, Factorio's headless server comes from factorio.com, Terraria ships TerrariaServer.exe with the game, and FiveM uses the FXServer artifacts from Cfx.re.

What hardware does a dedicated server need?

Less than the game itself in some ways, more in others.

• RAM is the big one. Light games run on 2 GB, big Unreal Engine survival games want 12 GB or more. The full table is in how much RAM a game server needs.
• CPU single thread speed matters more than core count. Most game loops run mostly on one thread, so one fast core beats eight slow ones.
• Fast storage helps with saves and loading new areas. NVMe is ideal, a hard drive is painful for large worlds.
• Upload bandwidth and a stable connection. Every player receives a constant stream of updates from the server.
• No graphics card. The server never draws anything.

Where can a dedicated server run?

Three places, each with a different trade off:

A VPS sits in between: rented hardware you set up yourself. We compare that option honestly in game server hosting vs VPS.

Do I need a dedicated server?

You do if any of these are true:

• People in your group play at different times and want the same world.
• The game's co-op mode caps players lower than you need. Palworld co-op stops at 4 players, a dedicated server goes up to 32.
• The game has no other way to host. Rust and DayZ community play is all dedicated servers.
• You want mods, plugins, whitelists, bans or custom rules.
• The host's PC lags when it runs the game and the world together.

If two friends always play at the same time and the game has a host button, you probably do not. Start there and move to a server when schedules drift.

What you get with a hosted dedicated server

On GamezServers you pick a game and a plan, pay, and the server is live in about 60 seconds with its own address and port. The panel gives you the parts of a dedicated server people actually touch: a live Console that accepts any command, one click buttons for common jobs, a Files tab for configs, SFTP for big uploads, and 3 one click backups. Every server has DDoS protection. Plans start at 4.99 USD a month for 2 GB, and you can see every game on the games page.

FAQ

Is a dedicated server the same as a private server?

Not exactly. A private server is any server only your group can join, usually through a password or whitelist. A dedicated server can be private or public. Most private servers people rent are dedicated servers with a password set.

Can I play on my own dedicated server?

Yes. You connect to it like anyone else, using its address. On the same PC you can usually connect to 127.0.0.1 or localhost with the server's port.

Does a dedicated server reduce lag?

Usually, if the alternative is one player hosting on a busy PC with weak upload. It does not fix a player's own bad connection, and it can still lag if it is short on RAM or CPU. See why is my game server lagging.

Is a dedicated server free?

The software almost always is. What costs money is the machine it runs on and the electricity, or a monthly hosting fee if you rent one.

Do dedicated servers need a powerful PC?

They need plenty of RAM and a fast CPU core, not a graphics card. A modest PC with enough memory can run a small server well.
