Mindustry is the best free alternative to Factorio: a free, open-source factory automation game with conveyor logistics and production chains, plus a tower-defence layer where enemies attack your network. It uses bounded maps and shorter sessions rather than Factorio's endless world, and installs in about 250 MB.
Both are about conveyor belts, throughput and production ratios. One costs money and never discounts; the other is free and adds a combat layer that changes how you build.
| Mindustry | Factorio | |
|---|---|---|
| Price | Free, open-source (GPL-3.0) | Paid, never discounted |
| Perspective | Top-down 2D | Top-down 2D |
| Map structure | Bounded maps — a series of optimisation puzzles | Effectively endless single world |
| Combat | Central — waves attack your network | Peripheral — biters are a nuisance |
| Install size | ~250 MB | ~2 GB |
| Multiplayer | Co-op and PvP, free public servers | Co-op |
| Session length | Short — a map is an evening | Long — a save is a month |
| Modding | Built-in browser, JSON and Java | Extensive, Lua |
You want it free, you like defined objectives and shorter sessions, you want combat to shape your layouts, or you want PvP.
You want the deepest possible logistics simulation, an endless world to grow into, and you do not mind paying full price.
Commercial, published by Wube Software. Not in the PlayBound catalog — it is not free, and never discounts.
Official siteMindustry is what happens when a tower defense game decides it wants to be a factory simulator and then accidentally becomes an RTS. We picked it because it keeps adding another layer—mining, logistics, production, power, defenses, research—until you're no longer defending a base so much as operating an increasingly ridiculous industrial machine.
