How to Host a Project Infinity 0.1 Server in 2026 (Complete Guide)

If you want to host a Project Infinity 0.1 server for your friend group, this guide covers everything: what specs you actually need, how the setup process works, what breaks most often, and how to skip the painful parts entirely.

Project Infinity 0.1 is not a beginner modpack. It's a large skyblock tech modpack running on Minecraft 1.20.1 with Forge, built around Mekanism, Applied Energistics 2, Blood Magic, Botania, and dozens of other heavy mods. It's designed for players who want technology, magic, and cosmic exploration — build compact automation or colossal factories, craft custom multiblocks, and tackle an ambitious endgame. It currently has over 296,000 downloads on CurseForge and is still actively updated, with the latest release dropping in June 2026.

Running it on a server is a different challenge than running it on your own PC. Here's what you need to know.

What is Project Infinity 0.1?

Project Infinity 0.1 is a skyblock modpack focused on long-term progression, blending advanced technology, deep magic, and cosmic exploration. It includes Mekanism with two major addons, Blood Magic, Botania, AE2 with addons, void miners, and much more.

It's categorised as "Extra Large" on CurseForge — which is CurseForge's way of saying this pack is resource-intensive by design. The mod list is extensive, the progression is long, and the server has to handle complex automation, multiple dimensions, and custom multiblock structures running simultaneously.

The modpack is still in early development, so expect occasional crashes and bugs. The developer actively pushes updates — the hotfix from June 22, 2026 is the current stable release. This also means server files change frequently, and keeping up with updates is part of the ongoing maintenance.

Minimum Server Requirements for Project Infinity 0.1

This pack needs real resources. Don't underspec it and wonder why everyone gets kicked every 20 minutes.

Why so much RAM?

AE2 networks, Mekanism factories, and Botania automation all run simultaneously and generate significant server-side load. The pack is skyblock, which means world generation is lighter than an overworld pack — but the automation complexity more than compensates for that. Once players start building serious AE2 storage systems and Mekanism reactors, RAM usage climbs fast.

Java version: Java 17 or Java 21. The pack runs on Forge for Minecraft 1.20.1 — Java 8 will not work. If your host lets you pick the Java version, use Java 21 for better garbage collection performance.

Forge version: The current hotfix runs on Forge 47.4.x. Version 0.0.48.2 updated Forge to 47.4.20 specifically — if you're running an older Forge version you'll hit startup errors that look completely unrelated to the actual cause.

Storage: The server files zip is around 685 MB. With world data and player data, budget at least 20 GB of storage — more if you plan to play for weeks and build large bases.

How to Create a Project Infinity 0.1 Server

Step 1: Download the server files

Go to the Project Infinity 0.1 page on CurseForge. Look for the file labelled Serverfiles — the current version is Serverfiles_Project_Infinity_0_1_0.0.50.2-hotfix.zip. Do not use the client modpack files for your server — they're different packages.

Step 2: Extract and configure

Extract the zip to your server directory. Open the server.properties file before starting and set your memory allocation. Do not set it lower than 8 GB. If you're on a Linux server:

java -Xms4G -Xmx10G -jar forge-1.20.1-[version].jar nogui

Adjust Xmx to match your available RAM minus 1-2 GB for the operating system.

Step 3: Accept the EULA

Open eula.txt and change eula=false to eula=true. The server will not start without this.

Step 4: First startup

The first startup takes significantly longer than normal — expect 5 to 15 minutes depending on your hardware. The server is loading hundreds of mods, generating mod registries, and building the initial world. This is normal. Do not kill the process because it looks frozen.

Step 5: World generation

Be sure to create the world with cheats enabled. The developer specifically flags this in the CurseForge description — some modpack progression and debug features require operator commands. Do this at world creation, not after.

Step 6: Port forwarding

Open port 25565 on your router if you're self-hosting. If you're using a hosting provider, this is handled automatically.

Common Problems When Running a Project Infinity 0.1 Server

Server crashes immediately on startup

Most commonly caused by wrong Java version (Java 8 instead of Java 17/21) or insufficient RAM allocation. Check your Java version first: java -version in terminal. If it says 1.8.x, you need to upgrade.

"Missing or unsupported mandatory dependencies" error

This usually means you're using the client files instead of the server files, or a mod in your install is expecting a library that didn't ship with the server package. Re-download the correct Serverfiles zip from CurseForge.

First startup never finishes

If the server hangs for more than 20 minutes on first start, it's usually a RAM issue — the JVM can't allocate what you've set in the startup flags. Check that your Xmx value doesn't exceed physical RAM, and that no other processes are eating memory.

Server starts but everyone gets kicked / TPS drops to 2-3

Classic sign of underspecced RAM once players start building. AE2 networks and Mekanism machines are the most common culprits. Check your TPS with /forge tps in console — anything below 15 TPS is a problem. Solution: more RAM, or tuning the JVM garbage collector flags (G1GC works well for modded servers). If this keeps happening, read our guide on why a modpack can max RAM with zero players online — the same logic applies once people start building.

Crash after updating the modpack

Before updating the modpack, make sure to back up your world. This is the developer's own warning. The pack is actively developed and mod removals between versions can corrupt chunks that contain blocks from removed mods. Always back up before updating, never update mid-session.

"A powerful force has invaded your world" message spam

This was a known issue in earlier versions — the developer patched it out in a recent update. If you're seeing it, you're on an outdated version. Update to the current hotfix.

Can You Host Project Infinity 0.1 With Friends?

Yes, and it's genuinely a great pack for a friend group — the long-term tech and magic progression keeps groups busy for weeks. But there are a few things to know about running it multiplayer specifically.

The RAM requirements scale with players. A solo server running fine at 8 GB will start struggling with 4 players once everyone has active automation running. Budget for 10-12 GB minimum for a group of 3-5.

Updates happen frequently — the developer has been pushing updates roughly every few weeks. Each update can change mod lists, which requires a server-side update and sometimes a world reset for affected chunks. Coordinate updates with your group so nobody logs in mid-update.

The skyblock starting experience requires everyone to begin in the same world. Make sure your server seed and world settings are configured before the first player joins — you can't change the starting island setup after the world generates.

Why Project Infinity 0.1 Needs Good Hosting

Most of the problems above — wrong Java version, insufficient RAM, crash-on-update, TPS issues — are things that happen on servers where nobody is watching or knows what to look for.

Self-hosting on a spare PC works if you have the technical knowledge and don't mind the maintenance. Most friend groups have one person who ends up managing everything while everyone else just plays.

Budget hosting (shared nodes, oversold VPS) falls apart under pack this size. A server labelled "8 GB RAM" on a shared node competes with dozens of other servers on the same physical machine. When other customers spike their usage, your TPS tanks. Project Infinity's automation load makes this worse than vanilla — you're running constant background calculations that are sensitive to CPU and memory availability.

The pack also updates frequently enough that someone needs to stay on top of new releases, back up the world before updating, and handle the mod conflict resolution when something breaks between versions. That's ongoing work, not a one-time setup.

Host Project Infinity 0.1 on Piggo

Piggo is managed modded Minecraft hosting built specifically for packs like Project Infinity 0.1. Here's what that means in practice:

Send us the CurseForge pack link — we install it, configure Java 21, set the correct JVM flags, and have your server running before you've finished reading this guide. First startup confusion, EULA setup, Forge version matching — we handle all of it.

When a pack update drops and you want to upgrade, we back up your world first, apply the update, verify the server starts cleanly, and let you know when it's ready. You don't manage the update process.

When TPS drops because your group built a massive AE2 system, we tune the garbage collector settings and diagnose which automation is causing the load. You don't read crash logs.

Full file access on every plan — no locked folders, no restrictions. If you want to adjust configs or add a specific mod, you have direct access to everything.

Recommended plan for Project Infinity 0.1:

• 1-3 players: Standard (8 GB) — €16/month
• 3-6 players: Plus (10 GB) — €20/month
• 6+ players or heavy automation: Heavy (12 GB) — €24/month

Free 48-hour trial, no card required. Tell us you want Project Infinity 0.1 and we'll have it set up and running.

FAQ

What version of Forge does Project Infinity 0.1 use?

The current version (0.0.50.2-hotfix) runs on Forge 47.4.x for Minecraft 1.20.1. Use the Serverfiles package from CurseForge, not the client modpack files.

How much RAM do I need for 4 players?

10 GB minimum, 12 GB recommended once players have active Mekanism and AE2 automation running.

Does Project Infinity 0.1 update frequently?

Yes. The developer has been pushing updates regularly throughout 2026. Always back up your world before applying updates, as mod removals between versions can corrupt chunks.

Can I run Project Infinity 0.1 on a free host?

Free hosts like Aternos don't have the resources to run a pack this size reliably for a group. You'll hit RAM limits immediately.

What Java version does it need?

Java 17 or Java 21. Java 8 is not compatible with Minecraft 1.20.1 or Forge 47.x.

How long does the first startup take?

5 to 15 minutes on decent hardware. This is normal — don't kill the process.

Can Piggo migrate my existing Project Infinity world from another host?

Yes. Send us your world files and we'll import them. If you're moving from a host with restricted file access, our Exaroton migration guide covers the same principles for a large Forge modpack.

What if the server crashes after a mod update?

Message us in Discord. We'll identify which mod change caused the crash and either roll back the update or resolve the conflict.
