Visualizing the Dependency Graph
go mod graph (Built-in)
go mod graph
Output: each line contains two space-separated fields (module and its requirement) in path@version format:
example.com/main github.com/google/uuid@v1.6.0
example.com/main golang.org/x/text@v0.3.7
github.com/google/uuid@v1.6.0 golang.org/x/sys@v0.0.0-20210615035016
go mod why
go mod why -m github.com/some/module
Shows the shortest import path from your code to the module — useful for understanding why an unexpected dependency exists.
Generate a Graph Image with modgraphviz
Pin modgraphviz as a module tool, then pipe go mod graph into it.
go get -tool golang.org/x/exp/cmd/modgraphviz@latest
go mod graph | go tool modgraphviz | dot -Tpng -o deps.png
Green nodes represent versions selected by MVS (in the final build list). Grey nodes are versions that exist in the requirement graph but are not used.
Interactive Visualization with go-mod-graph
go-mod-graph (samber/go-mod-graph) is a web-based interactive dependency explorer with zoomable graph, module weight indicators, searchable module list, and MVS algorithm visualization.
Complementary Analysis
Pin digraph as a module tool for graph queries.
go get -tool golang.org/x/tools/cmd/digraph@latest
# General graph queries on go mod graph output
go mod graph | go tool digraph reverse example.com/some/module
