How to run a server yourself, step by step for real — then an honest look at what changes if you use uniz.host
Setting up a server, by game
How to run your own Minecraft server, from zero to friends joining (and the shortcut that skips the work)
You can run a Minecraft server for free on your own PC: install Java 25, download server.jar from minecraft.net, run java -Xmx2G -jar server.jar nogui, accept eula.txt, then open port 25565 for friends. The real limits: your home IP changes almost daily, the PC must stay on, and many home connections sit behind CGNAT where port forwarding is impossible — the alternative is hourly hosting from ฿0.30/hour.
How to run your own Palworld dedicated server (SteamCMD) — and why budget players end up on hourly hosting
A Palworld dedicated server is a free install via SteamCMD (app 2394010), but it is genuinely RAM-hungry — the practical minimum is 8GB, growing with the number of Pals in the world — and it uses port 8211/UDP. If you'd rather not run a PC 24/7, hourly hosting bills only while the server is online, and you can set it to sleep by itself when empty.
The basics worth knowing
Minecraft server crashes after adding mods? Read the error, then pick the right Java runtime
A line reading UnsupportedClassVersionError or class file version 61.0 means the mod or loader was compiled with a newer Java than the one your server is running on. The cause: Java is picked from the Minecraft version number, which is only correct for vanilla — mod loaders and modpacks have their own requirement that the game version cannot express. The fix: take the class file number from the error and subtract 44 to get the Java version it wants (61 minus 44 = Java 17), switch the server to that Java, then start it again.
What is port forwarding? How to let friends join the server on your home PC
Port forwarding tells your router to pass incoming internet connections to the machine running your server — Minecraft uses port 25565, for example. But many Thai home connections sit behind CGNAT, which makes forwarding impossible no matter what you configure; you either request a public IP from your ISP or run the server on a host instead.
How much RAM does a game server need? Minecraft, Palworld, and picking a size that doesn't waste money
Minecraft Java can start at 1–2GB for 2–5 friends without mods; plan on 4–6GB for modpacks. Palworld is far heavier — its real minimum is 8GB, growing with the number of Pals in the world. The clearest signs you're short on RAM are rhythmic lag spikes and the server restarting itself.
