Anchor Optimizer
by Walksy
With Anchor Optimizer, charging and blowing up a respawn anchor responds at once on the client, even on a server with high ping.
What it does
Normally the client holds off showing any change to an anchor until the server confirms it. When latency runs high, the charge sound can lag behind the glowstone click, and the anchor may still be standing after it has already gone off. The mod plays the charge sound as soon as glowstone is added, and removes the anchor and the glowstone around it as soon as it explodes, without waiting for the server. The server still computes the real explosion and its damage.
The mod is a client-side only Fabric mod and requires WalksyLib. The code is released under the MIT License, and the mod was first published on 2025-06-26. Files cover 1.21 – 26.3 across 17 release versions, and the latest Fabric file, 1.3.0+26.3, is for 26.3 and dates from 2026-10-09.
Key features
Instant charge sound
The charge sound plays the moment glowstone is added, rather than after the server confirms the change.
Immediate anchor removal
The anchor and surrounding glowstone disappear as soon as the explosion is triggered on the client.
Server opt-out
Server owners can disable the client-side behavior for their players through WalksyLib's opt-out plugin.

What the author says
This mod handles respawn anchor interactions client-side, so charging and blowing up anchors isn't held back by your ping. By default, the client waits for the server before it shows anything happening to an anchor. On high ping that means a delayed charge sound and an anchor that stays in place after you've already…
