There is no single best Arma 3 host for every group. The right choice depends on simultaneous players, AI and script load, mod size, player geography, file-management tools, backup requirements and how long you will rent the server. GTX Gaming is the easiest option to size from published slot-and-RAM examples; Host Havoc stands out for Workshop collections, FTP and headless-client support; Nitrado is worth checking when you need unusually broad slot or rental-term choices.
The figures below are provider-listed configurations and prices observed in 2026, not controlled benchmarks. Use them to build a shortlist, then test the exact region, mission and mod collection your unit will run.
What should you look for in Arma 3 server hosting?
Start with the workload rather than a headline slot number. Arma 3 performance is affected by player count, AI entities, scripts, terrain complexity and server-side mods. A 40-slot milsim with heavy AI can need more resources than a lightly modded 80-player event.
Capacity and memory
Count your expected peak simultaneous players, then leave headroom for AI and scripts. Slot ceilings are allocation limits, not tested guarantees of tick rate or smoothness. GTX Gaming publishes plans from 10 to 120 slots and RAM upgrades through 32 GB. Host Havoc displays 40- to 128-slot configurations. Nitrado is described with adjustable configurations from 4 to 200 slots.
Mod and file workflow
For a modded unit, verify Workshop collection import, server-only mod handling, signature-key support, custom mission PBO uploads and FTP or SFTP access. These details determine whether adding a new terrain or converting a mission takes minutes or requires support intervention.
Location and latency
Choose a data-center region near most players, but do not treat a long location list as proof of good routing. Have players test ping from their normal home or campus connections, preferably during the evening when local networks are busiest.
Administration and recovery
Check whether the panel supports scheduled tasks, sub-users, permissions, configuration editing, automated backups and one-click restores. Ask how long backups are retained and whether restoring a previous state also restores missions, keys and mod configuration.
Total cost
Compare the complete checkout configuration in your currency. Include tax, billing term, renewal price, RAM upgrades, storage, location surcharges and optional backup or support products. A low monthly headline can become expensive after those additions.
How do the main Arma 3 hosts compare?
The following table collects the published options relevant to Arma 3 groups. “Not stated” means the available material did not establish a comparable figure.
| Provider | Published capacity | Published memory information | Mod and file tools | Backup or recovery features | Example 2026 price |
|---|---|---|---|---|---|
| GTX Gaming | 10–120 slots | Up to 5 GB included; upgrades to 8, 12, 16, 24 and 32 GB | Workshop support, server-only mods, keys and custom mission PBO uploads | Not stated in the cited plan material | £9.99/month for 10 slots; £24.98 for 40 slots with 8 GB; £42.98 for 80 slots with 12 GB. An Australian regional page lists A$19.54 for 10 slots through A$111.45 for 120 slots. |
| Host Havoc | 40–128 slots displayed | Not stated in the cited product material | Steam Workshop and collections, mods and DLC, full FTP/file manager, headless-client support | Automated offsite backups and easy restores | $20.00/month for a displayed 40-slot configuration before term choices and add-ons |
| Nitrado | 4–200 slots described | Not stated | Configuration depends on the selected plan; verify the exact mod and file features before ordering | Verify backup and restore options for the selected product | US reference of $16.19 for 10 slots for 30 days; terms described from 3 to 365 days |
None of these published figures establishes independent CPU performance, uptime, support quality or real-world latency for a particular mission. Treat words such as “high performance” or “low ping” as claims to validate with your own workload.
Is GTX Gaming a good choice for a modded Arma 3 unit?
GTX Gaming is the easiest of the compared providers to size from the information published for 2026, especially if you know your target slots and RAM requirement.
Published sizing examples
Its regional page lists 10 slots at A$19.54 per month, 20 at A$23.45, 30 at A$33.22, 40 at A$43.00, 50 at A$50.82, 60 at A$58.65, 70 at A$62.56, 80 at A$70.38, 90 at A$78.20, 100 at A$82.11, 110 at A$95.80 and 120 at A$111.45. The page shows up to 5 GB of RAM included, with paid tiers reaching 8, 12, 16, 24 and 32 GB.
The same material labels 40 slots with 8 GB as suitable for a modded unit using ACE3 and CBA_A3, and 80 slots with 12 GB for heavier mod lists. Those are the provider’s sizing recommendations, not independent benchmarks. A separate October 2026 guide records £9.99 per month for 10 slots, £24.98 for 40 slots with 8 GB and £42.98 for 80 slots with 12 GB. Currency, tax, location surcharge and renewal pricing can change the final bill.
File and mod workflow
GTX documents Workshop support, server-only mods, signature keys and custom mission PBO uploads. That combination is useful when clients need a curated collection while the server also runs dependencies that should not be downloaded by players. Confirm whether your chosen plan requires downtime when changing RAM or applying a major mod update.
Who should choose it?
Choose GTX when you want a visible slot-and-memory ladder and can map your group to one of the published examples. It is a practical starting point for a 20- to 40-player milsim or an 80-player server with a known heavy collection, provided you validate CPU behavior with your actual mission.
What does Host Havoc offer for Arma 3 mods and administration?
Host Havoc is most compelling when your priority is a straightforward Workshop and file-management workflow rather than a published RAM table.
Mod and file controls
The product page lists Steam Workshop integration and collection support, mod and DLC support, full FTP and file-manager access, and headless-client support. These tools let an administrator upload custom missions, maintain server-side files and automate a collection without waiting for a host-side ticket.
Backups and locations
Host Havoc lists automated offsite backups and easy restores. Locations shown include North America, Europe and Asia-Pacific. Select the region that minimizes latency for the majority of your roster, then have representative players test it before moving a long-running campaign.
Price and hardware wording
A displayed 40-slot configuration is priced at $20.00 per month before billing-term choices and add-ons. The provider also states, “Your own Arma 3 dedicated server, mods and headless clients.” It separately says, “Unlike most hosting providers, we own & operate our own hardware.” These are provider statements, not independently verified measurements, so ask which CPU resources, storage limits and upgrade rules apply to your exact plan.
Who should choose it?
Host Havoc fits units that regularly import Workshop collections, use headless clients, or need direct FTP access. Confirm the included memory, storage, restart policy and backup retention because the cited product material does not provide a comparable RAM figure.
When does Nitrado make sense for an Arma 3 server?
Nitrado is worth investigating when you need a very small or very large slot configuration, or when a short rental term matters more than a standard monthly commitment.
Range of slots and terms
The comparison material describes configurations from 4 to 200 slots and rental terms from 3 to 365 days. A US reference display shows $16.19 for 10 slots for 30 days. Treat that amount as a volatile snapshot: country, taxes, renewal, storage and included options must be checked at checkout.
Questions to ask before ordering
- Does the exact product support your Workshop collection and server-only mods?
- What RAM, CPU allocation and storage accompany the selected slot count?
- What happens to the world, configuration and backups when a short term expires?
- Can you export missions, keys and configuration files if you migrate?
Who should choose it?
Nitrado is a candidate for a short event, seasonal campaign or group that needs a slot count outside the common 10- to 120-slot ladder. Its advertised ceiling of 200 slots should be treated as an allocation option, not evidence that a 200-player mission will maintain a stable simulation.
Which host fits common Arma 3 group sizes?
Use your scenario to narrow the shortlist, then verify the workload-specific details before paying.
Six to 10 players in a private group
Start with a 10-slot plan in the region that produces the best measured ping. GTX’s £9.99 example and Nitrado’s displayed US $16.19 30-day offer are reference points, not guaranteed totals. A small slot count does not remove the need to check mod storage, restart controls and backups.
Twenty to 40 players in a modded campaign
Compare GTX’s published 40-slot/8 GB example with Host Havoc’s displayed 40-slot configuration. Give priority to Workshop collection import, server-only mod handling, custom mission uploads, signature keys and the location serving most players. If your missions use dense AI or long-running scripts, leave memory and CPU headroom rather than buying exactly the expected player count.
Eighty players or a public server
Use capacity as an initial filter, then request details on CPU allocation, storage, restart behavior, support escalation and migration. GTX publishes an 80-slot/12 GB example, while Nitrado advertises up to 200 slots. No available source proves which provider delivers the best CPU performance or uptime at this scale, so load-test the actual mission and mod collection.
Short event or seasonal campaign
Nitrado’s stated 3- to 365-day term range is useful to investigate for an event that does not need a year-round subscription. Confirm the exact expiry behavior, backup retention and cancellation rules before selecting a short term.
How can you estimate the real monthly cost?
Build a complete configuration rather than comparing the largest number on a landing page.
- Choose the slot ceiling. Use peak simultaneous players, not the size of your community or Discord.
- Add workload headroom. Account for AI, scripts, terrain and server-side mods; select a RAM tier where the provider publishes one.
- Select the region. Record any location surcharge and confirm that the region is available for your chosen slot tier.
- Add operational features. Include storage, backups, extra IPs, scheduled tasks or support products if they are optional.
- Price the renewal. Check tax, currency conversion, promotional expiry and the recurring price after the first term.
- Record downtime conditions. RAM upgrades, plan changes or migrations may require a restart, which matters during a campaign.
For example, the GTX figures show why 40 slots with 8 GB and 80 slots with 12 GB should not be compared only by player capacity: they represent different memory allocations and different workloads. Likewise, Host Havoc’s $20.00 display and Nitrado’s $16.19 30-day reference use different currencies, terms and potentially different inclusions.
How do you verify a host before moving your campaign?
Ask for operational details in writing and test the exact setup during a refundable or low-risk period when possible.
- Measure representative latency. Have players in each major region ping the proposed location from their normal networks at peak hours.
- Deploy the real collection. Import the Workshop collection, server-only mods, keys and your largest mission rather than a lightweight showcase mission.
- Exercise administration. Create a restricted sub-user if supported, schedule a restart, edit a configuration value and upload a custom PBO.
- Test recovery. Create a backup, change a harmless setting, restore it and confirm that the server returns with the correct mission, keys and mod state.
- Observe the busy case. Run the maximum expected players and AI while watching server FPS, desynchronization and script errors. Record your own results; published slot ceilings do not supply these measurements.
- Document support paths. Save the emergency contact method, escalation hours and migration/export procedure before the first public event.
What can go wrong, and how do you recover?
The server starts but players cannot join
Check that the client collection matches the server collection, that required signature keys are present, and that the selected game branch and mission are compatible. Re-upload the mission PBO and inspect the startup command for missing server-only mods.
Players join but the simulation slows
Reduce unnecessary AI, inspect scheduled scripts and test the mission without optional mods. If the issue persists at the same player count, ask the host about CPU allocation and contention, then compare results after moving to a higher-memory or higher-capacity tier.
A mod update breaks the campaign
Keep a copy of the last working collection, keys, configuration and mission files. Pin or roll back the changed mod, restore the previous files and test on a private password-protected instance before reopening the public server.
A restore does not return the expected world
Determine whether the backup includes saves, profiles, configuration, keys and uploaded missions or only the game directory. If the provider’s restore scope is limited, maintain an independent copy of those files and export them before every major update.
The bill is higher than the advertised price
Review currency conversion, tax, location charges, RAM upgrades, billing term and renewal pricing separately. A promotional first term or a monthly display may not represent the recurring total.
What should you confirm in the final pre-purchase checklist?
- Peak simultaneous slots and expected AI or script load are written down.
- Included RAM, upgrade tiers and any upgrade downtime are clear.
- The chosen region has been tested from representative player connections.
- Workshop collections, server-only mods, signature keys and custom mission PBO uploads are supported.
- Backup frequency, retention, restore scope, support escalation and migration terms are documented.
- The full recurring price includes tax, add-ons, location charges and renewal.
- A rollback copy of the last working mod collection and mission files is stored outside the host.
Frequently Asked Questions
Can I move an existing Arma 3 campaign between hosts?
Usually you need more than the mission file: export the server configuration, profiles, keys, Workshop collection definition, custom PBOs and saved-game data. Ask the destination host which directories it accepts and perform a private restore test before changing DNS or inviting players.
Do Arma 3 slot numbers include headless clients?
Do not assume they do. Ask the provider how headless-client connections are counted and whether they consume the same CPU, memory and connection allowance as players; the published figures here do not define that policy.
How much RAM does a 40-player Arma 3 server actually need?
There is no universal number because AI, scripts, terrain and server-side mods change the workload. One provider labels 40 slots with 8 GB as a suitable modded-unit example, but treat that as a sizing suggestion and validate it with your mission.
What happens when a short Nitrado rental expires?
The available description confirms terms from 3 to 365 days but does not establish a universal expiry or data-retention rule. Check the exact product’s renewal, grace period, backup retention and export options before choosing a short term.
Can a 200-slot plan reliably host 200 players?
A 200-slot listing indicates an available configuration ceiling, not a guaranteed simulation rate at 200 players. Demand a workload test or trial using your mission, AI and mod collection, and verify CPU allocation and support limits in writing.
