NightVisuals AutoSprint
by NightVisuals
NightVisuals AutoSprint keeps the player sprinting while the forward movement key is held, so a single double-tap is enough to start a run.
What it does
Once active, the mod engages sprinting on every tick in which the player moves forward, and the sprint continues without the sprint key being held down. The behavior is handled by a lightweight check that runs inside the player tick event, so no extra rendering work is added. The mod is limited to the 1.21.4 game version and loads on Fabric.
AutoSprint can be switched on and off from the NightVisuals GUI, which opens with a default key and is where its settings live. It needs Fabric API and NightVisuals GUI installed beside it, and it uses its own config files rather than sharing settings with other mods. Because it runs only on the client, a server does not need it for players to use it.
The mod is released under All rights reserved and is not open source. Files exist for Fabric for 1.21.4, the latest being version 1.0 from 2026-06-29, and the page lists it as a utility.
Key features
Automatic sprint
Sprinting continues whenever the player moves forward, so the sprint key does not have to stay pressed during a run.
Smart auto-sprint
Sprinting is engaged only when forward movement is actually happening, which keeps standing still from triggering it.
Toggle from the GUI
The feature can be enabled or disabled through the NightVisuals in-game GUI menu, bound to a default key.
Vanilla movement compatible
The sprint follows vanilla movement mechanics and is described as causing no rubberbanding or desync.
Low overhead
The logic runs within the player tick event and adds no extra rendering cost, according to the author.

Use cases
Long walks and exploration
Players crossing large terrain can keep moving forward without holding the sprint key for the whole trip.
Who it’s for: Players on the 1.21.4 game version who want sprinting to continue while they move forward, and who already use the NightVisuals GUI or are willing to install it.
How it compares
Adaptive Sprinting is a Fabric mod for 1.21.4 that is client-side only and open source under the MIT License. Auto sprint fixed is also client-side only and under the MIT License, but it targets 26.1.2 and is not open source. AutoSprint, by contrast, is client-side only, licensed All rights reserved and not open source, with its own in-game toggle and its own config files.
