Thymine
Thymine is a Fabric client mod that fixes small bugs and changes a set of combat and movement visuals, including sneak, sprint and hurt effects.
What it does
Thymine applies a handful of client-side tweaks. Sneaking no longer plays the lowered camera animation, and the hurt animation can be turned off. Fire is drawn lower on the screen, the sneak height is raised, and the potion effects screen stays open at all times. A night vision effect is also available.
Sprinting can be switched to a toggle, so the key does not need to be held. On servers that run ViaVersion, the swimming pose is disabled. Only the client needs the mod, and servers run without it. Thymine requires Fabric API and the Fabric loader, and its file list spans the 1.16 line up to 1.21.11.
Files are published for Fabric alone, under the MIT License, and the source code is open source. The current release is 1.8.11 for 1.21.11, dated 2026-05-10, and the first build appeared on 2023-02-09.

How it compares
Toggle Sneak & Sprint is a Fabric, client-side mod under the CC0 1.0 Universal license, published for 1.19 – 1.21 and covering sneak and sprint toggles only. ToggleSprint is also a Fabric client mod, open source under the Mozilla Public License 2.0, but its files target only 1.8.9. Always Sprint is a Fabric client mod under the GNU General Public License v3.0 or later, with files for 1.14.4 – 1.21.10, and it keeps sprinting active rather than offering a toggle. Thymine covers a wider set of visual changes across its own file list.
