Best Factorio Mods for Multiplayer Servers (2026, 2.0 and 2.1)

The best Factorio mods for multiplayer in 2026 are quality of life mods that help a team share a base, like Factory Planner, Rate Calculator, Even Distribution, Todo List and Factory Search, plus big overhauls such as Krastorio 2 or Space Exploration for groups that want a longer game. Every mod below has releases for both stable 2.0 and experimental 2.1.

How we picked these Factorio multiplayer mods

Every pick below was checked on the official Factorio mod portal in October 2026 and has a release for Factorio 2.0 (stable 2.0.77) and Factorio 2.1 (experimental). That matters on a server, because the server and every player must run the exact same mod versions. Factorio handles that for you: when a player joins, it offers to download the server's mods at the right versions.

Two rules for multiplayer mods:

Every mod runs on every machine. Factorio has no client only mods, so a mod one player wants is a mod the whole server runs.
Some mods change balance for everyone. Reach or cheat style mods affect all players, so agree on them as a group.

Best quality of life mods for teams

These are low risk, work on existing maps and make shared factories easier to run.

Mod	What it does	Why it helps in multiplayer
Factory Planner	Plans production lines and calculates machine counts	Everyone can see the same plan for a build
Helmod	Production planner with deep calculations	Alternative to Factory Planner for detailed ratio work
Rate Calculator	Select an area to see its input and output rates	Quickly check if a teammate's build is keeping up
Bottleneck Lite	Coloured lights show which machines are starved or blocked	Spot problems in someone else's part of the base
Factory Search	Search the whole map for any item or entity	Find where a teammate stored those 400 blue circuits
Even Distribution	Drag items to spread them evenly across machines	Faster setup when building together
Auto Deconstruct	Marks depleted drills for deconstruction	Keeps mining outposts tidy without anyone babysitting them
Squeak Through 2	Walk between pipes, belts and machines	Less getting stuck, which everyone appreciates
Text Plates	Buildable letters and symbols	Label areas so the team knows what goes where

Factory Planner and Helmod do the same job. Pick one for the server so your team shares one tool.

Best mods for coordinating a team

Big shared factories need a way to say who is building what.

Mod	What it does
Todo List	A shared task list where players add, assign and complete tasks
Task List	A lighter task list for teams, from the author of Rate Calculator

Either one stops two players from building the same smelter array on opposite sides of the map.

Best logistics and train mods

Mod	What it does	Notes
Project Cybersyn	Automatic train dispatching based on supply and demand	Great for large rail networks shared by many players
Teleporters	Buildable teleporters by Klonan, a Wube developer	Gets a scattered team together fast on big maps
Jetpack	Fly over obstacles and water	Popular with overhaul packs, changes how you move around

Best overhaul mods for a long multiplayer game

Overhauls change the tech tree and recipes, need a fresh map and use more memory. They are the best reason to run a dedicated server, because a group can play them for months.

Mod	Style	Good for
Krastorio 2	Expanded tech tree, new resources and buildings, polished balance	Groups who finished vanilla and want more
Krastorio 2 Spaced Out	Krastorio 2 combined with Space Age	Space Age owners who want Krastorio content
Space Exploration	A huge space themed overhaul by Earendel, separate from Space Age	Very long campaigns for dedicated groups
Pyanodons (start with Pyanodons Coal Processing)	Extremely deep, complex production chains	Veteran teams with a lot of time
Bob's mods and Angel's mods	Classic modular overhauls of metals, chemistry and refining	Groups who want to mix and match

Space Exploration and Space Age are separate takes on going to space, so check each mod's page for which game setup it expects before you create the map. Our Factorio Space Age multiplayer guide explains how the expansion is switched on or off on a server.

How much RAM do modded Factorio servers need?

Quality of life mods barely change memory use. Overhauls do. A vanilla or lightly modded map fits in 2 GB, Space Age or a growing modded factory wants 4 GB, and big overhauls like Space Exploration or Pyanodons are happiest on 8 GB. Startup time also grows with mod count, which is normal.

Performance in Factorio is mostly about UPS on every player's computer, not just the server, because every client simulates the full map. Heavy overhauls on a megabase can slow the slowest player's PC first.

Should you use these mods on Factorio 2.1?

You can. Every mod in this list already has a 2.1 release, but on 2.1 experimental you will be running the newest mod builds too, so expect the odd bug. If your group wants stability, stay on 2.0.77 stable. Factorio picks the right mod version for your game version when you download through the in game mod browser. More in the Factorio 2.1 update guide.

If players start getting disconnected with desync reports after you add a mod, that mod is the first suspect. See the Factorio desync fix.

How to add these mods to your server

Install the mods in your own game from the in game mod browser and test them on a new map.
Copy the zips from your Factorio mods folder, along with mod-list.json and mod-settings.dat.
Stop the server, back up, upload the files to the server's mods folder and start it again.
Players join and accept the mod sync prompt.

The full walkthrough is in how to install mods on a Factorio server.
