Renting is the better default for most public Garry’s Mod communities: you get a provisioned game-server instance, datacenter connectivity and a control panel without maintaining the underlying computer. Self-hosting can cost less for a small private group that already owns suitable hardware, has dependable upload capacity and is comfortable managing SteamCMD, firewalls, updates and reboots.
The right choice depends on total monthly cost, required control, concurrent players, gamemode and addon load, uptime expectations, and how much maintenance you are willing to do. The comparison below shows exactly what each model requires and how to choose without relying on a misleading universal RAM, bandwidth or break-even figure.
What is the difference between self-hosting and renting a Garry’s Mod server?
Self-hosting runs the dedicated server on a computer and internet connection you control. Renting places the server on a provider-managed instance in a datacenter; you pay a recurring fee for allocated resources and access through the provider’s tools.
| Decision factor | Self-hosting | Renting |
|---|---|---|
| Up-front cost | Use an existing computer or buy one, then provide storage and networking. | Usually little or no hardware purchase. |
| Ongoing cost | Electricity, internet, repairs, storage, backups and the value of your administration time. | Recurring plan fee, plus any separately priced backups, extra slots or add-ons. |
| Control | Full operating-system, server-file, launch-flag, backup and network control. | Control-panel and file access within the provider’s limits and policies. |
| Setup | Install SteamCMD and the server, configure a token, firewall and router, and maintain updates. | Provision through the provider’s panel or support process. |
| Reliability | Depends on your power, ISP, router, machine and maintenance. | Depends on the provider’s location, hardware, network and outage handling. |
| Scaling | Replace or upgrade hardware and upload capacity yourself. | Change plans when the provider supports a suitable upgrade. |
| Best fit | Technical owners, private groups and workloads needing operating-system access. | Public communities, quick launches and owners who want a clear support boundary. |
Neither model guarantees a particular tickrate or player count. Garry’s Mod performance changes with gamemode, map, physics and prop activity, addon behavior, tickrate, concurrent players and other services sharing the machine.
How do I self-host a Garry’s Mod dedicated server?
Self-hosting is a repeatable process, but every part of it becomes your responsibility. Facepunch’s Windows and Linux instructions use SteamCMD to install Garry’s Mod AppID 4020, then start the srcds server with launch parameters.
Windows installation
- Install SteamCMD and choose a permanent server directory such as
C:gmodserver. - Open a command prompt and install or validate the dedicated server:
steamcmd +login anonymous +force_install_dir C:gmodserver +app_update 4020 validate +quit - Open the required game-server port in Windows Firewall and your router. The exact port and transport should match your server configuration and ISP capabilities.
- Create a launch shortcut or batch file. A basic Sandbox example is:
srcds.exe -console -game garrysmod +maxplayers 16 +gamemode sandbox +map gm_construct +sv_setsteamaccount YOUR_GSLT - Replace the token and settings with your own values. A Workshop collection can be supplied through the appropriate launch parameter; keep the collection ID in your startup file so a restart uses the same content.
- Run the server, join from another connection, and confirm that the server appears and that addons load before inviting a full group.
Facepunch documents a Game Server Login Token (GSLT) setup as mandatory for ranking. Treat the token as a secret: do not publish it in screenshots, repositories or shared configuration files.
Linux installation
- Use a supported Linux installation with enough disk space, a command-line session and basic command-line skills.
- Install SteamCMD, then download AppID 4020 into a dedicated directory:
./steamcmd.sh +login anonymous +force_install_dir /home/gmodserver +app_update 4020 validate +quit - Start the server with
srcds_run, for example:./srcds_run -game garrysmod +maxplayers 16 +gamemode sandbox +map gm_construct +sv_setsteamaccount YOUR_GSLT - Configure the host firewall and router, and place server settings and launch arguments in a script that can be reviewed and backed up.
- Create an update script that stops the process, runs SteamCMD validation, and starts the server again. Test the script manually before scheduling it.
- Add a reboot-start mechanism. Facepunch’s Linux guide demonstrates using
crontab; without an explicit service or scheduled start,srcds_runwill not automatically return after a machine reboot.
Use a service manager or another supervised process if you need automatic restarts after crashes, but understand how it handles logs, environment variables and shutdowns before putting it in production.
What you must operate after installation
- SteamCMD updates and validation, including checking that an update did not break a gamemode or addon.
- GSLT creation, rotation and protection.
- Workshop collections, manually installed addons, server configuration and launch flags.
- Operating-system patches, disk monitoring, log review and malware protection.
- Router and firewall rules, port forwarding and testing from outside your home network.
- Planned reboots, crash recovery, backups and restoration drills.
What does renting change?
A rented plan moves the physical machine, datacenter network and much of the provisioning work to a hosting company. You still choose the gamemode, map, player limit and addons, and you remain responsible for the content and configuration inside the server account.
A provider control panel commonly exposes file management, console or RCON access, server.cfg editing, Workshop collections and restart controls. Confirm those features before ordering; “managed” does not mean every operating-system package, binary or custom service is available.
Example plan sizes
Flux lists the following Garry’s Mod examples in 2026. They illustrate one provider’s offers, not a market-wide capacity standard or a guaranteed player count.
| Advertised player count | vCores | RAM | SSD | Listed price |
|---|---|---|---|---|
| 16 | 2 | 3 GB | 20 GB | $4.99 per month |
| 32 | 2.5 | 4 GB | 30 GB | $5.99 per month |
| 64 | 3 | 5 GB | 40 GB | $7.49 per month |
Actual headroom depends on the map, gamemode, physics activity and addon set. A plan labeled for 64 players is not proof that every 64-player DarkRP or heavily scripted server will maintain the same performance.
How much does each option really cost?
Compare a complete monthly equivalent rather than comparing a hosting invoice with zero dollars. For self-hosting, include the equipment and every recurring input:
Self-hosting monthly equivalent = (hardware purchase ÷ expected months of use) + electricity + incremental internet cost + storage/backups + administration timeFor renting, use:
Renting monthly cost = current plan fee + separately charged backups, extra slots or add-onsSelf-hosting cost inputs
- Hardware: Amortize the purchase over the period you realistically expect to use it. If you already own a spare computer, count its electricity, replacement risk and the value of using it for another purpose.
- Power: Measure or estimate the machine’s actual draw while the server is online, then apply your local electricity rate.
- Internet: Include any higher tier needed for upload capacity, data allowance or a public address.
- Storage and backups: Budget for a second copy of configurations, maps, addon data and logs. A backup on the same disk does not protect against disk failure.
- Administration: Assign a realistic value to update windows, troubleshooting, player support and recovery after an outage.
Rental cost inputs
- Check whether the advertised price is recurring, promotional or tied to a billing term.
- Verify the server location, included storage, backup policy, extra-slot pricing and resource limits.
- Ask whether support covers only the host platform or also configuration and addon problems.
- Check export and cancellation procedures before you build a large community around the account.
Flux reports about 175 MB idle memory on a Sandbox server with a 21-addon Workshop collection. It also reports about 7 GB for a base installation, with addons ranging from hundreds of megabytes to several gigabytes. Those are Flux’s 2026 measurements, not universal requirements; active players, props and large addon packs can raise both memory and storage use substantially.
How should I size hardware for a self-hosted server?
No authoritative source establishes one CPU, RAM or bandwidth number for every Garry’s Mod population and addon set. Size from the workload you intend to run, then measure during a busy session rather than buying from a player-count slogan.
CPU and simulation load
Prioritize strong per-thread performance and cooling when the gamemode runs substantial Lua, NPC or physics work. More cores help when the computer also runs databases, monitoring, web panels or other services, but a high core count does not automatically fix a saturated game-server thread.
Memory
Reserve memory for the operating system and other services, then leave headroom above the server’s observed peak. Measure after the full Workshop collection is mounted and several players are creating props or entities; an idle reading is only a baseline.
Storage
Use an SSD for the operating system and server files when possible. Account for the base install, downloaded Workshop content, maps, logs, crash dumps and at least one separate backup destination. Addon collections can grow from hundreds of megabytes to several gigabytes.
Network capacity
Upload requirements vary with player count, gamemode, entity activity and network settings. A stable, reachable connection matters more than a headline download speed. Watch upstream utilization during peak play and leave margin for other household traffic.
Physical host choice
A mini PC or small desktop can be a sensible category for a small private server, but select the model from its CPU performance, RAM capacity, SSD, cooling and Ethernet capability. Do not treat a specific form factor as a universal recommendation.
What networking and uptime work does home hosting require?
A home server must remain reachable while your router, ISP and computer are operating. Configure the server’s listening port, create a matching firewall rule, forward the port on the router and test from a connection that is not on the same local network.
Common reachability failures
- Local-only testing: A server can appear reachable from the host’s own network while outside players cannot connect. Test from a mobile connection or another location.
- Changing address: If the home’s public address changes, the connection details shared with players may stop working. Use an address or name that your ISP and router support, and document how it is updated.
- Carrier-grade NAT or blocked inbound traffic: Some ISPs do not provide usable inbound connections on consumer plans. Ask the ISP for an appropriate option or use a rented instance.
- Router reboots: A reboot can remove a port-forward rule or change the host’s local address. Reserve the host’s local address and recheck the rule after firmware changes.
- Household congestion: Upload saturation causes latency even when the server process has spare CPU. Schedule large backups outside play sessions and monitor upstream use.
Wired Ethernet is a reasonable optional accessory for a home host because it avoids wireless interference. Cat 6 is not mandatory; the requirement is stable, reachable connectivity.
Which option is more reliable for a public community?
Renting removes your home power, router and ISP from the server’s physical path, but it does not eliminate outages. You still need to evaluate the provider’s location, network history, maintenance communication, backup limits and recovery process.
Self-hosting can be highly reliable when it uses a dedicated machine, stable power, monitored storage and a tested restart procedure. It is also vulnerable to a single household failure: an ISP outage or a failed router takes the community offline until you intervene.
For either model, write down who can access the console, where backups live, how to restore the latest configuration and what players should be told during maintenance. Reliability is an operating practice, not a feature label.
How do addons, Workshop collections and custom services affect the choice?
Workshop collections simplify distribution but can make startup time, storage and memory unpredictable. Keep a record of collection IDs and versions, remove unused content, and add new packages one at a time so you can identify a faulty addon.
Self-hosting is preferable when you need operating-system services, custom daemons, unusual file access or a database alongside the game server. Renting is simpler when the provider explicitly supports your gamemode, collection, RCON and server.cfg workflow. Ask about file and process restrictions before assuming a rented account can run arbitrary software.
Which choice fits each use case?
| Situation | Better starting point | Reason |
|---|---|---|
| Small private group and an unused computer | Self-hosting | You can avoid a new hardware purchase if upload capacity, reachability and uptime are adequate. |
| Public or rapidly growing community | Renting | Provisioning is faster and the underlying network and hardware are outside the home. |
| Heavy addons plus custom operating-system services | Self-hosting, or a specialized provider | You need confirmed OS-level control; choose a provider only if it explicitly supports those files and limits. |
| Uncertain demand | Rent month to month | Measure real CPU, memory, storage and network use before committing to hardware. |
| Strict data-location or access requirements | Whichever offers verified controls | Check the provider’s region and policies, or document your own physical and account security. |
What are the most common mistakes, and how do I fix them?
Choosing RAM from the player-slot number
Symptom: The server starts but slows or crashes when players, props and addons become active. Fix: Record peak memory with the complete collection and workload, then add operating-system headroom or move to a larger plan.
Assuming download speed proves upload capacity
Symptom: Players report lag while a speed test looks fast. Fix: Measure upstream use during a busy session, stop competing uploads and verify that the ISP permits inbound hosting.
Forgetting restart persistence
Symptom: The server is missing after a power or operating-system reboot. Fix: Test a supervised startup script or crontab entry, verify permissions and confirm that the server returns without an interactive login.
Putting a token in public files
Symptom: Someone else can use the server login token. Fix: Revoke and replace the token, restrict file permissions and keep secrets out of public repositories and screenshots.
Installing a whole collection at once
Symptom: You cannot identify which addon caused errors or a startup failure. Fix: Add content in small batches, keep a known-good collection and check logs after each change.
Comparing only the advertised monthly fee
Symptom: Self-hosting appears free until electricity, backups and troubleshooting consume time, or a rental bill grows with extras. Fix: Apply both cost formulas and use the same accounting period for every option.
Can I start rented and move to self-hosting later?
Yes, provided you keep portable copies of server.cfg, launch arguments, Workshop collection IDs, addon lists, maps and any database exports your gamemode uses. Download and test those files before canceling the rented instance; provider snapshots and file-export procedures differ.
Plan for a DNS or connection-address change, a fresh firewall and router setup, and a maintenance window while players reconnect. The reverse move is also possible, but a rented provider may restrict operating-system access or custom services, so migration should be part of the original selection criteria.
What should I check before committing?
- Write down expected peak players, gamemode, map rotation, addon collection and any other services on the machine.
- For self-hosting, test upload stability, inbound reachability, power behavior and a complete reboot-and-restore procedure.
- For renting, verify location, included vCores, RAM, SSD, backups, extra-slot pricing, control-panel access and cancellation terms.
- Calculate the monthly equivalent for both choices, including administration time.
- Start with a private test session, monitor CPU, memory, disk and network use, and adjust before advertising a public opening.
Frequently Asked Questions
Can I host a Garry’s Mod server on the same PC I use to play?
You can, but the game client and dedicated server compete for CPU, memory, storage and upload capacity. A separate machine is safer for consistent simulation, especially when the server runs physics-heavy addons or a large public player count.
Do I need a GSLT for a private Garry’s Mod server?
Facepunch documents GSLT setup as mandatory for ranking. If ranking is not part of your private session, confirm the current server rules for your intended mode rather than assuming a token is required or optional in every situation.
How many players can 3 GB of RAM support?
There is no reliable player number from RAM alone. The gamemode, map, props, Lua scripts, Workshop collection and other services can change usage substantially, so monitor peak memory under the exact workload.
What happens if my home internet uses carrier-grade NAT?
Inbound connections may not reach a self-hosted server even when local clients can connect. Ask the ISP whether a public inbound address or suitable hosting option is available; otherwise, a datacenter-hosted instance avoids that home-network limitation.
Should I rent a server if I only play occasionally?
A month-to-month plan can be practical because you pay only during active periods and avoid leaving a home computer powered on. Compare the rental total for your actual play months with the electricity and setup time of self-hosting.
