Cullify
Cullify, a client-side optimization mod by Fluxsyum Studios, hides distant decorative vegetation from the renderer so fewer draw calls and vertices are sent to the GPU.
What it does
Decorative vegetation such as grass, flowers, ferns and kelp is the set of blocks Cullify targets. Blocks beyond a configured distance from the player are skipped during rendering, which reduces the rendering load. The blocks themselves stay in the world; only what is drawn changes, so gameplay and collisions are untouched. Culling boundaries can be set as one of eight geometric shapes and checked along the horizontal X/Z plane, the vertical Y axis, or both.
Cullify needs Embeddium, Reese's Sodium Options and Sodium to run. The mod attaches to the internal LevelSlice rendering path used by Sodium, and it runs next to Sodium Options. The mod is published for Fabric, Forge and NeoForge, with files for 1.20.1, 1.21.1 and 26.1.2, and is released under the GNU General Public License v3.0 only, so the code is open source. Only the client needs it; servers do not have to install anything.
Key features
Vegetation culling
Decorative plants beyond a set distance are not sent to the renderer, lowering rendering load and vertex throughput.
Geometric culling shapes
Eight shapes define the culling boundary around the player, and each can be tuned to match the view.
Density filter on the outer ring
Outer vegetation is thinned with a deterministic hash filter, dropping 75 percent at the far edge and 50 and 25 percent in the zones before it.
Double-tall plant sync
Both halves of double-tall blocks such as sunflowers and tall grass are culled together, which prevents visual gaps.
Statistics overlay
While a player is in a world, an overlay on the screen shows counts of culled blocks, water swaps, chunk updates and draw calls.

How it compares
Sound Culling is a different mod: it is client-side, open source under the MIT License and published for 1.20.1 – 26.3 on Fabric, Forge and NeoForge. Sodium Leaf Culling is open source under the MIT License, client-side only and built for Fabric and NeoForge on 1.21.1 alone. Cullify, by contrast, covers Fabric, Forge and NeoForge for 1.20.1, 1.21.1 and 26.1.2 and targets vegetation rather than sound or leaves.

What the author says
Cullify is a client-side mod that culls decorative vegetation blocks (such as grass, flowers, ferns, algae, and kelp) based on distance from the player and customizable geometric shapes. By preventing distant or non-visible vegetation blocks from rendering, it reduces rendering load (vertex throughput and draw calls)…
