Async Locator
Changes the searching of features to be asynchronous to mitigate associated lag
About this Mod
Looking for later versions?
Check out Alvaro842DEV's port for 1.21+
Modifies vanilla behaviour when locating features to run asynchronously, mitigating associated lag.
This is currently implemented for:
- Locate command when executed by a user
- Villager explorer map trade offers
- Dolphin treasure finding
- Exploration map in chests (v1.1.0+)
This mod is only required to be installed server side! So clients only need this installed if they want it for single player.
This alone only works for vanilla (see list above). Other mods may need to implement usage of this mod themselves to make use of the async functionality.
Incompatabilities
Mods that affect vanilla's structure locating features may impact Async Locator's functionality.
Right now, the list below states other mods that I'm aware of:
- Structure Essentials
Has been seen that on startup only one of either Async Locator's or Structure Essentials' locating improvements will work. No real issues otherwise, but only one of the mods are required.
Mod Integration
Other mods can also use Async Locators as a dependency to implement the asynchronous locating into their own code.
To do so, please use CurseMaven or Modrinth Maven to add this mod to your build.gradle, and then make use of the AsyncLocator class and/or logic classes.

Async Locator server crashes on startup – what to do?
Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.20.2). You can switch loaders with one click in the panel.
Is Async Locator compatible with fabric and forge?
Async Locator officially supports fabric, forge for Minecraft 1.20.2, 1.20.1, 1.20. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Async Locator – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Async Locator consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
