Extrapolate
by CC_PCT
Extrapolate changes how entity positions are estimated on the client, replacing interpolation with a prediction based on the last known position and velocity.
What it does
Extrapolate predicts where an entity is heading from its current and last recorded position, rather than blending between two known points. The aim is a more accurate entity position when packets arrive late, so entities keep moving smoothly despite server delay. A configurable weight controls how far ahead the prediction reaches. Small values near 0.4 are recommended, since larger ones can cause entities to jitter.
The extrapolated position is used only for the hitbox, so entity rendering stays identical to vanilla. Interpolation is still available: disabling extrapolation returns entities to the standard method, which can help if a setup shows jitter. The mod is built to work with the Cloth Config API, Fabric API and Mod Menu, all of which are required. It runs on Fabric for 26.1 – 26.3, and the environment is client-side only, so players install it and servers do not need it. The code is licensed under the GNU General Public License v3.0 or later and is open source.
Key features
Extrapolated hitboxes
Entity hitboxes follow a predicted position built from the current and last known location, instead of an interpolated one.
Adjustable prediction weight
A configurable weight sets how far ahead the position is predicted, with values near 0.4 suggested for lower latency.
Unchanged rendering
Only the hitbox uses the extrapolated position, so entity models render as they do in vanilla.
Toggle for interpolation
Extrapolation can be disabled to fall back to standard interpolation, for setups where entity jitter appears.

What the author says
Extrapolate is a Minecraft mod which extrapolates entity position instead of interpolates to get a more accurate entity pos despite server delay This mod improves this by predicting the position of entities based on the current and last position, making entity position more up to date.
