How to Make a Free Minecraft Server in 2026 (No Credit Card, Always Online)

The 3 Ways to Make a Free Minecraft Server

Before diving in, understand there are three approaches, each with different trade-offs:

Option 1: Hosting on OliveerF (Fastest — 60 Seconds)

This is the recommended option for 2026. OliveerF gives you a Paper 1.21 server with 2GB RAM, 30 player slots, and MySQL — completely free, always online, no queue. Here's the step-by-step:

1. Register a free account at oliveerf.sbs/hosting-portal.html — just your email, no credit card.
2. Click "New Server" in your dashboard. Enter a server name and select Paper 1.21.4.
3. Select the Free plan and hit "Create". The provisioning takes about 60 seconds.
4. Copy your server IP from the panel (format: abc123.oliveerf.sbs:25565).
5. Open Minecraft → Multiplayer → Add Server and paste the IP. Connect and you're in.

Option 2: Self-Hosting on Your PC (Full Guide)

If you want complete control or need a specific modpack, hosting from your own computer is viable. Here's what you'll need:

Requirements

• Windows 10/11, macOS, or Linux
• At least 8GB system RAM (4GB for Minecraft + 4GB for OS)
• Port 25565 opened in your router firewall
• Java 21 installed (required for 1.21.x)

Step 1: Install Java 21

Minecraft 1.21 requires Java 21. Download it from adoptium.net (free, open source). Install the JDK version for your OS. Verify with:

java -version
# Should output: openjdk version "21.x.x"

Step 2: Download PaperMC

Paper is the best server software for 1.21 — it's faster than vanilla and adds many configuration options.

# Visit papermc.io and download the latest 1.21.4 build
# Or use direct link:
curl -o paper.jar https://api.papermc.io/v2/projects/paper/versions/1.21.4/builds/latest/downloads/paper-1.21.4-latest.jar

Step 3: Create Start Script

Create a file named start.bat (Windows) with these recommended Aikar JVM flags:

@echo off
java -Xms2G -Xmx4G --add-modules=jdk.incubator.vector -XX:+UseG1GC -XX:+ParallelRefProcEnabled -XX:MaxGCPauseMillis=200 -XX:+UnlockExperimentalVMOptions -XX:+DisableExplicitGC -XX:+AlwaysPreTouch -XX:G1NewSizePercent=30 -XX:G1MaxNewSizePercent=40 -XX:G1HeapRegionSize=8M -XX:G1ReservePercent=20 -XX:G1HeapWastePercent=5 -XX:G1MixedGCCountTarget=4 -XX:InitiatingHeapOccupancyPercent=15 -XX:G1MixedGCLiveThresholdPercent=90 -XX:G1RSetUpdatingPauseTimePercent=5 -XX:SurvivorRatio=32 -XX:+PerfDisableSharedMem -XX:MaxTenuringThreshold=1 -Dusing.aikars.flags=https://aikar.co/2018/07/02/aikars-new-jvm-settings/ -jar paper.jar --nogui
pause

Step 4: First Launch & Accept EULA

# Run start.bat once — it will fail and create eula.txt
# Edit eula.txt and change:
eula=false
# to:
eula=true
# Then run start.bat again

Step 5: Configure server.properties

Key settings to edit before inviting friends:

# server.properties
server-port=25565
max-players=20
online-mode=true
motd=My Awesome Server
level-seed=           # leave blank for random
gamemode=survival
difficulty=normal
pvp=true

Step 6: Open Port 25565

For friends outside your home network to connect, you must forward port 25565 (TCP/UDP) in your router. The process varies by router model — search "port forward [your router brand]" for instructions. After forwarding, your external IP (find it at whatismyipaddress.com) is your server address.

Option 3: Aternos / Minehut — What They Don't Tell You

Aternos and Minehut are popular but have significant limitations that make them frustrating for regular use:

*Aternos allows unlimited players but performance degrades heavily above 15 due to shared RAM

Essential Plugins to Install First

Once your server is running (on any platform), install these free plugins to improve the experience:

EssentialsX — Must Have

Adds /home, /spawn, /tpa, economy commands, kits, and much more. Download from essentialsx.net. Always use the Paper-optimized build.

LuckPerms — Permissions System

The best permission management plugin. On OliveerF (with MySQL), LuckPerms can store all permissions in the database — syncing across multiple servers if you eventually expand.

# Install in /plugins folder, then in-game:
/lp user YourName permission set luckperms.* true
/lp group default permission set minecraft.command.teleport true

WorldEdit — Build Tool

Essential for builders. Copy, paste, fill areas, and undo mistakes instantly. Available at enginehub.org/worldedit. The Paper build has better performance than the original.

Vault — Economy Bridge

Required by most economy plugins. Vault acts as a middleware layer between plugins like EssentialsX (economy provider) and ShopGUI+ (economy consumer).

GriefPrevention — Land Protection

Players can protect their builds using a golden shovel. Essential for public survival servers to prevent griefing. No configuration needed out of the box.

Free Server Performance Tips

Whether self-hosted or on a free cloud tier, here's how to squeeze maximum performance out of limited resources:

Optimize server.properties

# server.properties — performance settings
view-distance=8          # reduce from default 10
simulation-distance=6    # reduce from default 10
sync-chunk-writes=false  # async chunk writes

Optimize paper.yml

# paper-world-defaults.yml (Paper 1.20+)
entity-per-chunk-save-limit:
  experience_orb: 16
  arrow: 16
  fireball: 8
  firework_rocket: 8
anti-xray:
  enabled: true
  engine-mode: 2

Top 3 Performance Plugins

• 🗜️ ClearLag — removes excess entities periodically
• ⚡ Chunky — pre-generates world chunks (eliminates explore lag)
• 📊 Spark — profiler to identify performance bottlenecks

Setting Up Whitelisting on a Free Server

For private servers (friends only), enable the whitelist to prevent strangers from joining:

# server.properties
enforce-whitelist=true
white-list=true

# In-game commands:
/whitelist on
/whitelist add PlayerName
/whitelist list
