Garry's Mod Servers: The Complete Guide

Garry's Mod is not a game with servers. It is a platform on which people have built about a dozen different games, all of which happen to share a menu.

This is the thing that confuses everyone arriving from anywhere else. Picking a Garry's Mod server is not picking where to play, it is picking what to play, and the difference between two servers can be larger than the difference between two entirely separate titles.

The gamemodes, and what each one is

The gamemode is the whole decision. Everything else is detail.

Sandbox. No objective. Build things, spawn props, experiment with the physics gun. This is the original mode and the reason the game exists. Sandbox servers explained covers what people do on them.

DarkRP. Roleplay in a town, with jobs, money, drugs, police and an economy. By a distance the most played gamemode and the most misunderstood. DarkRP explained covers the jobs and the rules, both of which are considerably more structured than they appear from outside.

Trouble in Terrorist Town. Social deduction: a handful of traitors among innocents, in a shooter. Excellent, and heavily dependent on the server being well moderated. TTT explained.

Prop Hunt. One team hides as scenery, the other seeks. Silly, forgiving, and one of the best modes to arrive on as a newcomer. Prop Hunt explained.

Deathrun. One player triggers traps along a course, everyone else tries to reach the end. Deathrun explained.

Murder, Hide and Seek, Cinema, Zombie Survival, Jailbreak and a long tail of others, some with dedicated communities of a few hundred people who have been playing together for a decade.

Garry's Mod gamemodes explained is the fuller map. The point to take from it before browsing is that filtering by gamemode is the first thing to do, not the last.

The download

Garry's Mod servers download custom content on first join, and the amounts are the largest of any game in this directory. Servers accumulate workshop collections — models, maps, sounds, weapons, and a large DarkRP server can ask for several hundred items before you can play.

This is worth planning around rather than being surprised by:

Expect minutes, not seconds, on a first join. Start it while you are doing something else.

Check the population before you commit. A four-minute download that ends on an empty server is the most common bad first experience in this game.

It is one-off. The second visit is instant, and the third. Do not clear your download cache to save disk space; it is the thing that makes returning painless.

A stalled download is usually the server. Content served from a misconfigured host crawls or hangs; there is nothing you can change. Why modded servers take so long to join covers both sides.

Reading a listing

Gamemode first. If the listing does not say, the name usually does, DarkRP servers announce themselves.

Player count against slots. Garry's Mod servers often run large caps. 20/128 is a quiet server; 60/64 is a busy one.

Peak hours. Gamemode communities are small and regional. TTT and Prop Hunt in particular are near-empty outside their peak and full inside it. Peak hours is the check that stops you dismissing a good server.

The store. DarkRP servers are where the most developed monetisation in this directory lives, and some of it affects play significantly. Spotting a pay-to-win server is a minute well spent before you invest in a character.

The rules. More consequential in Garry's Mod than almost anywhere, because most gamemodes here are held together by rules the code does not enforce. A DarkRP or TTT server with vague rules is a server where disputes are settled by whoever is loudest. The rules worth reading before you join applies directly.

Why moderation matters more here

In most games, breaking the rules means playing badly. In Garry's Mod it frequently means ruining the round for everyone else — killing without a valid reason in TTT, random deathmatch in DarkRP, blocking a course in Deathrun.

None of this is prevented by code. It is prevented by an admin being present, which means the quality of a Garry's Mod server is almost a function of whether staff are around at the hour you play.

The practical test: connect at peak and see whether anyone with a coloured name says anything. A server where admins are visible and talking is a different experience from one where the same map has been running unattended for six hours.

The addons you will meet

Garry's Mod servers are assembled from workshop content, and a handful of addons appear so often that recognising them tells you what a server is.

Wiremod and Advanced Duplicator on a sandbox server mean building is the point: contraptions, machines, and saved constructions people bring with them. A sandbox server without them is a prop-spawning server.

PAC3 lets players customise their model in detail. Common on roleplay servers, occasionally disabled because it is also the easiest way for someone to make themselves an eyesore.

ULX or ServerGuard are the admin frameworks. Their presence means someone thought about moderation; the commands are visible in chat when staff act.

A custom HUD and inventory on a DarkRP server usually means a well-resourced operation rather than a default install. Servers running stock DarkRP with no modifications tend to be somebody's first server.

Prop protection. Essential on sandbox and frequently missing. Without it anyone can delete anything you built, and a sandbox server with no prop protection is functionally an anarchy server.

Voice and text chat modifications, 3D voice, radio systems, proximity chat. Common on roleplay, and they change the social feel considerably.

You cannot see most of this from a listing. You can see all of it within five minutes of connecting, which is a good argument for treating your first visit to any Garry's Mod server as reconnaissance rather than commitment.

What the download size tells you

Worth reading as a signal rather than only as a cost.

A very large download usually means a server with years of accumulated custom content and a community around it. A very small one on a DarkRP server usually means a near-default install. Neither is decisive, but a server asking for six hundred workshop items has been somebody's project for a long time, and that correlates with the things you want; active staff, established regulars, and a place that will still be there next month.

The exception is a large download on an empty server, which is the worst combination available: maximum cost, unknown reward. Check the population first.

If you want to run one

Garry's Mod is a rewarding first server to run and a demanding one to run well.

Content discipline is the whole job. Every workshop item you add is added to every new player's first-join download. Collections grow, nobody prunes them, and eventually your join time is the largest thing standing between your listing and your player count. Audit it quarterly.

Set up fast downloads properly. Serving content from the game server's own connection is several times slower than from a web host. Many servers still do not, and the owners have never noticed because their own files are cached.

Addons break on updates. Garry's Mod updates regularly and the Lua ecosystem is large and unevenly maintained. Updating without breaking things is the discipline; the specific Garry's Mod version is that an addon whose author disappeared in 2021 will eventually stop working and nobody is coming to fix it.

Pick one gamemode. Running a DarkRP server and a TTT server and a sandbox server splits a population that was too small for one. When to run a second server covers the arithmetic, and the answer for a new Garry's Mod community is essentially always "not yet".

Staff are not optional. See above. A gamemode that depends on rule enforcement and has nobody enforcing rules degrades quickly, and moderating a community is the part that decides whether the server lasts a year.

Why the game refuses to die

Garry's Mod came out in 2006 and has a larger community-server population than most games released in the last five years. The reason is structural rather than nostalgic.

Every other game in this directory has a fixed thing you do, and servers vary how you do it. Garry's Mod has no fixed thing. When a gamemode gets stale, someone writes a new one, and the game becomes something else without any involvement from the developer. TTT did not exist at launch. DarkRP did not exist at launch. Prop Hunt did not exist at launch. All three now have communities older than most games.

This also means the game has no version churn in the way a live-service title does. A server running a gamemode from 2013 works, has its regulars, and will still be there next year. Games everyone says are dead covers the broader pattern; Garry's Mod is the clearest case of a game whose community-server population is the whole game rather than a supplement to it.

The practical consequence for someone arriving now: the depth is real, it is in the gamemodes rather than the game, and nothing you learn about one gamemode transfers to another.

Getting started

1. Pick a gamemode, not a server. Read the explainers if you do not know which you want.
2. Filter to it and sort by population.
3. Check peak hours for the three that look plausible.
4. Join the one with visible staff at its peak, and let the download run.
5. Watch a round before playing. Every Garry's Mod gamemode has conventions the rules do not state, and five minutes of observation covers most of them.
