## What it is
A command-line tool that analyzes the size of compiled Go binaries, breaking down size by packages, sections, and dependencies. It supports ELF, Mach-O, PE, and experimental WebAssembly formats with text, JSON, HTML, and SVG output plus interactive web and terminal UIs.

## Use cases
- analyze why my go binary is so large
- break down go binary size by package
- visualize compiled binary size as a treemap
- compare binary sizes between two builds
- find which dependencies bloat my go executable
- generate  report of binary section sizes
- explore binary size interactively in terminal

## When to choose
- you need detailed size breakdowns of Go-compiled binaries across platforms
- you want interactive treemap exploration via web or TUI
- you need machine-readable output (JSON) for CI size tracking or diffing builds

## When to avoid
- analyzing binaries not written in Go
- you need profiling of runtime performance rather than static size
- analyzing very large binaries in the browser WASM version, which is ~10x slower
