The internal 1x1 Lane splitter entity was added in Factorio 2.0. If fed a single-lane input, it distributes that lane across both output lanes, balancing them. However, for a full two-lane input AB, it just transposes the lanes to BA.
I haven't seen a mod make use of it, and I believe that's because it neither cleanly mixes nor swaps the lanes.
There is a closely related entity I think mods would use (in particular my mod has a need for it): a 1x1 Lane balancer that mixes cleanly. I imagine it might work by swapping between mapping AB->AB and AB->BA when one or more items pass by. It could use the same graphics as the Lane splitter.

I do use the current implementation but I agree it's not intuitive when compared to splitters.

I think it should replace the existing lane splitter though.

This request is still desired for my mod despite the new changes to inserter lane settings.

I think what you are looking for is Lane Balancers mod:
https://mods.factorio.com/mod/lane-balancers
(It does not even have control.lua, making it entirely scriptless)

I don't think you read the original post. It's nothing like what we're looking for, since it only swaps the 2 lanes if both have items on it.Zaflis wrote: Sat Jun 20, 2026 11:13 pm I think what you are looking for is Lane Balancers mod:
