What the settings do
These values come from our guided editors. Defaults are the editor starting values; they do not show the contents of a customer server.
Save in the background
Off: the server freezes the whole factory on every autosave — on large maps that means seconds of standstill for everyone. On: a child process writes the save while play continues.
Setting
non_blocking_saving
Default
false
Autosave interval
How often Factorio saves on its own. Large factories run more smoothly at 15 to 20 minutes.
Setting
autosave_interval
Default
10
Range / options
1 – 120
Number of autosaves
Factorio keeps this many automatic saves; after that the oldest one is overwritten.
Setting
autosave_slots
Default
5
Range / options
1 – 20
Pause when nobody is playing
The server halts the factory as soon as the last player leaves — nothing keeps running unattended.
Setting
auto_pause
Default
true
Pause while someone joins
Halts the game while a new player downloads the map. Without it, large maps stutter for everyone present.
Setting
auto_pause_when_players_connect
Default
false
Only admins may pause
Stops any guest from halting the running factory.
Setting
only_admins_can_pause_the_game
Default
true
Remove idle players after
0 turns the check off. Otherwise anyone idle for that long leaves the server.
Setting
afk_autokick_interval
Default
0
Range / options
0 – 1440
In-game console commands
Decides who may run commands in chat. Lua commands (/c) mark the save as modified for good.
Setting
allow_commands
Default
admins-only
Range / options
true, false, admins-only
Let regulars in on a full server
Anyone who has played on this server before gets in even when the player limit is reached.
Setting
ignore_player_limit_for_returning_players
Default
false
Upload limit in KB/s
0 means unlimited. A new player downloads the entire map; a limit keeps that download from slowing the running game down.
Setting
max_upload_in_kilobytes_per_second
Default
0
Range / options
0 – 1000000
Simultaneous uploads
This many players may download the map at the same time.
Setting
max_upload_slots
Default
5
Range / options
0 – 64
Minimum latency in ticks
Artificial delay that smooths out brief network jitter. 0 leaves the decision to Factorio.
Setting
minimum_latency_in_ticks
Default
0
Range / options
0 – 60
Save Name
Name of the save file
Setting
SAVE_NAME
Default
saves/default.zip
When it takes effect
Takes effect after saving and restarting the server.
Version
Floating release channel or an explicit version pin. Explicit pins are never advanced automatically.
Setting
FACTORIO_VERSION
Default
stable
When it takes effect
Takes effect after saving and restarting the server.
