Hytale Server Requirements
Official baseline requirements, recommended specs by player count, bandwidth expectations, dependencies, storage planning, setup steps, tuning tips, and FAQs - all in one place.
Tip: If you expect public traffic, prioritize consistent CPU performance, enough RAM headroom, and NVMe storage.
Official Dedicated Server Requirements
Ensure your Hytale Hosting provider meets these specs at a bare minimum.
Baseline (minimum)
- RAM: 4 GB+ available
- CPU: modern x64 / arm64 recommended
- Storage: SSD (NVMe preferred)
Best practice: set a clear memory limit (example: -Xmx8G) to avoid runaway RAM usage.
What matters most
- CPU: entity counts + busy hubs hit CPU
- RAM: view distance + scattered players raise memory
- IO: autosaves + backups benefit from NVMe
Rule of thumb: most lag is CPU/RAM before bandwidth.
Recommended Specs by Player Count
Practical guidance for smoother gameplay and headroom.
| Server size | Players | CPU | RAM | Storage | Notes |
|---|---|---|---|---|---|
| Small | 1–10 | 2 vCPU (high clock) | 4–6 GB | 30+ GB NVMe | Friends, testing, vanilla-style play. |
| Medium | 10–30 | 3–4 vCPU | 8–12 GB | 60+ GB NVMe | Best baseline for public/community servers. |
| Large | 30–80 | 6–8 vCPU | 16–24 GB | 120+ GB NVMe | Events, multiple worlds, heavier mods. |
| Enterprise | 80+ | Dedicated cores | 32 GB+ | NVMe + scheduled backups | Consider multi-server architecture + dedicated hardware. |
CPU matters most
Clustering players and entity-heavy areas usually become the first bottleneck.
RAM scales with activity
Exploration, view radius, and mods typically increase memory usage.
NVMe helps saves
Autosaves and backups benefit from fast IO, especially at higher player counts.
Bandwidth Expectations
Bandwidth varies by player activity, view distance, and how often players travel between areas. Use these ranges as planning guidance, then measure peak usage.
Rule of thumb (planning ranges)
| Players | Typical outbound | Peak bursts |
|---|---|---|
| 1–10 | 5–20 Mbps | 30+ Mbps |
| 10–30 | 20–60 Mbps | 100+ Mbps |
| 30–80 | 60–150 Mbps | 250+ Mbps |
| 80+ | 150+ Mbps | 500+ Mbps |
Outbound is usually the limiter. Expect bursts during events or when many players move/teleport at once.
What increases bandwidth
- Higher view distance / streaming radius
- Frequent movement between distant areas
- Large hubs with many players in one space
- Mods that increase sync/update frequency
For public servers, stable routing + DDoS protection matters as much as raw Mbps.
Dependencies
Common software components for stable, secure operation. Keep updates scheduled and test changes in staging.
Runtime
- JavaRequired (set -Xmx)
- Service managersystemd recommended
Leave OS headroom (don’t allocate 100% RAM to Java).
Networking & Access
- FirewallAllow game port (default 5520) & Optionally allow query port (default 5533)
- SSHKey-based login
- SFTPOptional for files
Avoid exposing extra ports and rotate credentials regularly.
Operations
- BackupsSnapshots + offsite
- MonitoringCPU/RAM/IO alerts
- Log rotationPrevent disk fill
Monitoring prevents surprise outages during peak hours.
Example: sane Java memory sizing
Adjust values to your plan - keep some RAM free for OS and caching.
# Example startup (adjust jar + paths)
java -Xms4G -Xmx8G -jar HytaleServer.jar --assets PathToAssets.zip
Storage Planning
Plan for more than your world folder: backups, logs, caches, and growth over time. Headroom prevents backup failures.
How much storage do I need?
| Server type | Suggested NVMe |
|---|---|
| Small | 30–60 GB |
| Medium | 60–120 GB |
| Large | 120–250 GB |
| Enterprise | 250 GB+ |
NVMe helps most during autosaves and backup creation/restores.
Backup headroom rule
- Keep 2–3× current world size free for local backups
- Use daily offsite snapshots for disaster recovery
- Rotate logs so they don’t silently fill disk
- Test restores monthly (the only reliable check)
Mods and multiple worlds increase storage faster than most people expect.
World growth factors
Scattered exploration and chunk generation are the biggest drivers of world size.
Retention strategy
Hourly (short), daily (medium), weekly (long) is a common and effective approach.
Restore speed
NVMe + snapshots can reduce downtime significantly on large servers.
Setup Quickstart
A clean checklist you can skim and follow.
- Prepare your runtime Install required runtime and verify it works.
- Upload server files Place server files + assets in a dedicated directory.
- First launch Start once to generate configs and verify permissions.
- Open ports Allow inbound traffic for your game port.
- Optimize Server Fine-tune and optimize your server resources.
- Go live Invite players and monitor CPU/RAM during peak.
Performance Tuning
Simple changes that usually improve stability quickly.
Reduce RAM spikes
- Lower view distance / view radius for public servers
- Keep autosave cadence reasonable
- Set a memory cap and leave OS headroom
Improve CPU performance
- Limit heavy entity/AI density in hubs
- Profile mods/plugins before production
- Split worlds/features into separate servers if needed
Mods & Plugins
Mods increase features - and resource usage. Plan accordingly.
Best practices
- Use a staging server for updates
- Update on a schedule (not during peak)
- Remove heavy mods you don’t need 24/7
Sizing with mods
- Add +2–4GB RAM for heavier modpacks on medium servers
- Expect CPU limits first when many players cluster
- For large modded servers, consider dedicated cores
Backups & Safety
A reliable routine that prevents painful data loss.
Recommended routine
- Backups every 30–60 minutes
- Daily offsite snapshots
- Retention: 7–14 days (longer for big communities)
Restore testing
- Test restores at least monthly
- Verify world + player data integrity
- Document restore steps for staff
FAQ
Quick answers to common questions.
A practical target is 8–12GB, depending on view distance, mods, and how scattered your players are.
If you would rather not bother with server setup or ongoing maintenance, direct Hytale hosting is the easiest option. A Hytale VPS is great for small/medium communities with consistent CPU resources and provides more control than direct Hytale hosting. For very large or heavily modded servers, dedicated cores/hardware provides the most stability. This is available with VDS hosting. Learn more about different Hytale hosting types.
RAM depends on player count, view distance, and mods. Small/private servers often run well with 4–6GB, while public/community servers typically need 8–12GB+. If players explore widely or you run heavier mods, plan for more headroom.
In most cases, CPU performance becomes the first bottleneck (busy hubs, entities, heavy mods), followed by RAM. Bandwidth is rarely the limiting factor unless you’re hosting very large public servers or experiencing network issues.
NVMe isn’t required, but it helps a lot with autosaves, backups, world loading, and restore times. If you’re running a public server or keeping frequent backups, NVMe is strongly recommended.
Bandwidth depends on player activity and settings. Most servers are fine on typical hosting connections, but you can see short bursts during events, fast travel, or when many players cluster and move at once. Monitor outbound traffic at peak to size accurately.
Not usually. Most lag comes from CPU saturation or memory pressure, especially with many entities, busy hubs, or heavy mods. Bandwidth helps, but it’s rarely the first thing to upgrade.
Mods typically increase RAM and CPU usage. Content-heavy or automation-style mods can raise tick/update work, while large modpacks often need extra memory. A safe approach is to add +2–4GB RAM for heavier setups and test updates on a staging server before applying them to production.
Start with the highest-impact changes: reduce view distance/streaming radius, limit entity-heavy areas (especially hubs), schedule backups away from peak hours, and remove or optimize heavy mods. If CPU stays high during peak, upgrading CPU resources is usually the next best step.
Yes. No matter how beefy your server is or how well your server is optimized, if your players are far from the host machine they will experience lag and high pings. Ensure your server is hosted as close as possible to your player base.
Most lag comes from CPU saturation (busy hubs, entity counts, heavy mods) or memory pressure (high view radius, scattered exploration). Monitor peak usage to confirm.
