It's a runtime for WASI blobs (basically a WASM based standard for crossplatform command line tools), for instance: emcc hello.c -o hello.wasm wasmer hello.wasm Hello World! This uses Emscripten as C compiler, but alternatively you can use the wasi-sdk toolchain instead of Emscripten to build WASI blobs: - https://github.com/WebAssembly/wasi-sdk https://github.com/WebAssembly/wasi-sdk ...or Zig as C compiler: zig cc -target wasm32-wasi hello.c -o hello.wasm wasmer hello.wasm Hello World! ...or of course Zig as Zig compiler :) zig -target wasm32-wasi hello.zig wasmer hello.wasm Hello World! (not sure if the Rust toolchain comes with builtin WASI support, but probably yes). ...or instead of wasmer use another WASI runtime: - https://github.com/wasmerio/awesome-wasi?tab=readme-ov-file#wasi-compatible-runtimes https://github.com/wasmerio/awesome-wasi?tab=readme-ov-file#... ...this is probably the best part of WASM and WASI, there's no 'vendor lock-in'.
