Full chipset support

Thanks to the usage of LLVM, Wasmer supports a broad range of chipsets, including x86 and aarch64 (ARM). So whatever chip you use – Wasmer will run on it.

Incredible Flexibility

One compiler doesn’t fit all sizes. Sometimes you want to focus on development speed (for which Cranelift is great), and other times you want to optimize for runtime performance… for which LLVM is unbeatable.
