InstaLoad
by MaGa118
With InstaLoad installed, switching worlds, joining servers and respawning no longer leave the player staring at a loading screen for long.
What it does
InstaLoad lets singleplayer worlds open before the spawn region has finished loading its 441 chunks on the 1.21.x builds. On 26.1.2 the same goal is reached through a ticket-based approach. Spawn chunks keep loading in the background, while the network world-loading logic keeps running as usual.
The mod covers world swaps, server joins, lobby switches and respawns. When a transfer stalls, a disconnect button shows up after half a minute, so the player is never left waiting indefinitely. The mod is client-side only, so servers run without it and players install it on their own game. Builds are version-specific: the 26.1.2 build will not load on 1.21.x, and the reverse applies too. Files cover 1.21 – 26.1.2 and are released under the MIT License, which is not open source.
Only the client needs the mod, so servers do not install it. The latest file is 1.2.2+26.1.2 for 26.1.2, published on 2026-08-16. Verified builds include 1.21.8 and later within the 1.21.x line.

What the author says
InstaLoad is a Fabric mod that makes world transitions feel instant. Join a server, switch lobbies, respawn, or load a singleplayer world without staring at a loading screen. The builds are version-specific: a 26.1.2 build won't load on 1.21.x and the other way around.
