Hi,

I am wondering if wasmtime supports IoT devices like Raspberry Pico, ESP32 C6, or something similar? Thank you!

The biggest problem is likely going to be architecture support. Cranelift and by extension Wasmtime currently doesn't support any 32bit target. Only x86_64, arm64, riscv64 and s390x are currently supported.

If you have a microcontroller with a supported architecture however, since https://github.com/bytecodealliance/wasmtime/pull/7995 it should be possible to run without an OS assuming you implement the functions of wasmtime-platform.h. The min-platform example takes almost 7MB as it includes not just the WASM runtime, but also the compiler. If you push a wasm module precompiled for the target to the microcontroller instead you can enable just the runtime part of Wasmtime, which cuts down the size to a little over 700k.
