## What it is
Twiggy is a code size profiler for WebAssembly binaries. It analyzes a binary's call graph to explain why functions are included and how much space could be saved by removing them.

## Use cases
- find why a function is included in my wasm binary
- reduce wasm binary size
- analyze retained size of functions in a wasm module
- profile code size of a rust wasm build
- identify dead code bloating my wasm output

## When to choose
- you ship WebAssembly and need to slim binaries
- you want call-graph-based size attribution for wasm

## When to avoid
- profiling native (non-wasm) binaries
- runtime performance profiling rather than size

## Facets
- artifact type: cli-tool
- maturity: active
- function: wasm, cli
- domain: developer-tools, performance
- platform: cli, rust, wasm
- tags: binary-size-analysis, wasm-optimization, profiler
