ELF, Mach-O, and PE binary formatstext, json, html, svgjson and text output)
Using Homebrew
brew install go-size-analyzer
Using scoop
scoop install go-size-analyzer
go install github.com/Zxilly/go-size-analyzer/cmd/gsa@latest
$ gsa --web golang-compiled-binary
Will start a web server on port 8080, you can view the result in your browser.
Or you can use the WASM version in the browser: GSA Treemap
[!NOTE]
Due to the limitation of the browser, the wasm version is much slower than the native version.
Normally costs 10x time to analyze the same binary.Only recommended for analysing small applications (less than 30 MB in size)
The web page will look like this:
You can click to expand the package to see the details.
$ gsa --tui golang-compiled-binary
