# CubeCL

5 Hacker News commenters recommended CubeCL and 2 criticized it, November 2025 to November 2026. It was recommended in 4 of 13 months.

**Verdict:** People recommend it for running Rust GPU kernels on WebGPU, Vulkan, CUDA, ROCm and Metal; the main caveat is thin documentation.

## Why people recommend it

- Targets many GPU backends (1 comments): "it supports WebGPU through WGSL and Vulkan through SPIR-V, along with CUDA, AMD via ROCm, and Metal" ([source](https://news.ycombinator.com/item?id=49741719))
- Rust macros for GPU kernels (2 comments): "Still blows my mind that they basically implemented a subset of Rust inside of a Rust macro" ([source](https://news.ycombinator.com/item?id=48565260)) "this is basically exactly what CubeCL does" ([source](https://news.ycombinator.com/item?id=47299583))
- Mojo-style GPU programming in Rust (1 comments): "if you want Mojo in Rust there is" ([source](https://news.ycombinator.com/item?id=49957723))

## What people warn about

- Thin documentation (1 comments): "lack of documentation and my lack of experience" ([source](https://news.ycombinator.com/item?id=47768532))
- Dependency seen as not ideal (1 comments): "pulling in CubeCL as a dependency is... not ideal." ([source](https://news.ycombinator.com/item?id=48742856))
