# How to Change Max Players on Your Factorio Server (/docs/factorio/player-slots)



import { Step, Steps } from 'fumadocs-ui/components/steps';

In `server-settings.json`:

```json
"max_players": 0
```

`0` = unlimited. Set a number to cap (e.g., `20`).

You can also change it at runtime:

```
/config set max-players 20
```
