goweight

A tool to analyze and troubleshoot a Go binary size.

✅ Get a breakdown of all modules inside a binary
✅ Supports Go 1.11 modules
✅ Output as JSON for tracking and/or monitoring as part of CI

Quick Start

With Go Modules - Go 1.11 or higher

$ go install github.com/Bevisy/goweight

Without Go Modules - Before Go 1.11

$ git clone https://github.com/Bevisy/goweight
$ cd goweight
$ go install

As an example, here's what goweight has to say about itself:

❯ ./goweight
execute: go build -C /root/go/src/github.com/bevisy/goweight -o goweight-bin-target -work -a
   13 MB runtime
  2.9 MB reflect
  2.3 MB math/big
  2.1 MB github.com/thoas/go-funk
  1.8 MB syscall
  1.6 MB encoding/json
  1.3 MB os
  1.3 MB time
  1.1 MB internal/abi
  976 kB regexp/syntax
  961 kB fmt
  823 kB internal/reflectlite
  ...

Or take the kube-apiserver component in kubernetes as an example:

❯ goweight ./cmd/kube-apiserver
execute: go build -C /root/go/src/github.com/kubernetes/kubernetes -o goweight-bin-target -work -a ./cmd/kube-apiserver
