Web49 is a WebAssembly toolkit and interpreter.
Try the first release! v0.0.1
Web49 contains a few tools for working with WebAssembly.
- interpreters
- miniwasm
- fast wasm interpreter
- uses technology from minivm
- supports multiple wasm formats
- wasm binary format: ~100% complete
- wasm text format: ~95% complete
- wasm spect test: ~75% complete
- includes a custom WASI implementation
- fast wasm interpreter
- raywasm
- wasm interpreter based on miniwasm
- miniwasm
- wasm binary tools rewrite
- much simpler than WABT's tools
- much smaller than Binaryen's tools
- wat2wasm
- convert wasm text into wasm binary
- wasm2wat
- generates nearly identical wat as binaryen or wabt
- turn wasm binary into wasm text
- supports all of wasm 1.0 and some extensions
- wasm2wasm
- shrink numbers in wasm files generated by llvm
- saves 0-4 bytes per 32 bit number
- saves 0-10 bytes per 64 bit number
- round trip parse and reemit
- shrink numbers in wasm files generated by llvm
Benchmarks performed by wasm3 and Web49's miniwasm. Ran on an 2020 Macbook Air (M1 + 8GiB ram) using bench.py.
All Benchmarks compiled with: emcc -O2
One can also view results run on github actions One can run the benchmarks for themselves.
- python3
- with pip
- emcc
- wasm3
- make
- tested with GNUMake
- works with BSDMake too
- and a C compiler
- gcc/clang/tcc works
- msvc would work if someone rewrites two macros
- #define NEXT() break
- #define LABEL(X) case X:
- probably a couple others
git clone https://github.com/fastvm/web49
cd web49
make CC=gcc # gcc is fastest in my tests
python3 -m pip install matplotlib
python3 bench.py
