About

Twiggy is a code size profiler for Wasm. It analyzes a binary's call graph to answer questions like:

• Why was this function included in the binary in the first place? Who calls it?
• What is the retained size of this function? I.e. how much space would be saved if I removed it and all the functions that become dead code after its removal.

Use Twiggy to make your binaries slim!
