Go Language Build & Module Cache (~/.cache/go-build)

Bottom Line: It is 100% safe to clear the Go build and module cache. Running go clean -cache will not delete your Go source code (.go files) or project dependencies.

What is the Go Build Cache Folder?

Located at ~/.cache/go-build on Linux/macOS or %LocalAppData%\go-build on Windows (plus $GOPATH/pkg/mod), this directory is created by the Go (Golang) compiler.

When you compile or test Go programs using go build or go test, Go caches compiled package object files so future builds compile instantly. Additionally, go get caches downloaded dependency modules in $GOPATH/pkg/mod.

Over months of building Go applications, these caches accumulate old package versions, taking up 5 GB to 20 GB+.

Can You Delete the Go Cache?

✅ Yes, it is completely safe to delete.

• No source code lost: Your .go code files, go.mod, and go.sum files are untouched.
• Auto-download on demand: Go will re-download modules and re-compile packages on your next go build.

How to Safely Clean Up Go Cache

Method 1: Using Built-in go clean Commands (Recommended)

To purge all compiled Go build artifacts:

go clean -cache

To purge downloaded module dependencies in $GOPATH/pkg/mod:

go clean -modcache

To purge both build cache and module cache in one command:

go clean -cache -modcache -testcache
