CubeCL is a Rust language extension, JIT compiler, and runtime set for writing high-performance GPU compute kernels in plain Rust. A single #[cube] function compiles on demand to CUDA, HIP, Metal, SPIR-V, WGSL, or CPU SIMD with compile-time specialization and autotuning.

Use cases

• write gpu compute kernels in rust
• compile one kernel to cuda and webgpu
• use tensor cores from rust
• build a multi-backend linalg library
• avoid writing wgsl or cuda c by hand
• autotune kernel launch configurations

When to choose

• you need peak-performance kernels across nvidia, amd, apple, and webgpu backends
• you want type-checked, testable kernels in rust instead of shader strings
• you're building scientific computing or deep learning infrastructure in rust

When to avoid

• you just need simple graphics rendering rather than compute kernels
• you want a high-level deep learning framework rather than a kernel layer
• your project doesn't use rust
