AutoSwap
by somik007
AutoSwap lets players move items between inventory armor and offhand slots with keybinds the player configures, so a totem or elytra can be swapped without opening the inventory.
What it does
Items can be toggled between the armor and offhand slots on a key press. Players define swap pairs that choose which two slots exchange, and automatic slot detection picks the correct target when an item is selected. Profiles store separate swap setups, such as one for PvP, one for elytra flight and one for a farm, and switching profiles changes every pair at once.
The mod is client-side only, so only the player's client needs it, and it works in multiplayer on servers. It requires Fabric API and Mod Menu, which must be installed alongside it on Fabric 1.21 – 26.1. Settings are opened through Mod Menu, where a language toggle switches the interface between English and Russian. Files are published for 1.21, 1.21.4, 1.21.11 and 26.1, and the code is open source under the MIT License.
Key features
Keybind item toggles
Items move between armor and offhand slots on a configurable key, without opening the inventory screen.
Configurable swap pairs
Each pair sets which two slots exchange, and the player adds or edits pairs through a Click + Add Swap control.
Swap profiles
Several setups can be saved and switched, for example separate profiles for PvP, elytra flight and farming.
HUD feedback
After a swap, the HUD shows the icons and names of the items involved, so the result is visible at a glance.

Use cases
Combat setups
A player can keep a totem in the offhand and switch to a different item in the same hand during a fight.
Elytra flight
A profile can hold a chestplate and an elytra pair, so the player swaps the two in one key press when landing.
Who it’s for: Players who switch between armor, offhand and other gear often, on Fabric clients for Minecraft 1.21 and later, including on multiplayer servers.
How it compares
Slot Lock is client-side only, open source under the MIT License and published for 1.21.11 – 26.1, so it covers the same versions without swap pairs. Toggle Toggle Sneak is also client-side only, under the MIT License, but is not open source and covers 1.21 – 26.3. Hotbar Quickswap is client-side only, open source under CC0 1.0 Universal, and targets 1.21.10 – 1.21.11.
