Go SSA Explorer lets you visualize the output of Go’s SSA compiler pass. It shows the genssa of your code, including inlining decisions, helping you understand how the Go compiler transforms your code.
Demos
SSA form demo
Inlay hints with inlining decisions demo
Features
Visualize SSA for any function or method
Enter a function or method name (e.g., package.FunctionName or (*Type).MethodName) and see its SSA form.
Supports inlining analysis
See which functions are inlined by the compiler and how Go transforms your code internally.
This feature is supported both in the SSA form and directly in the source code using inlay hints.
Inlay hints can be toggled either via the “Toggle inlining decisions” command shown at the very top of the file, or with the keyboard shortcut:
Windows/Linux: Ctrl+Alt+I
macOS: Cmd+Alt+I
Hot-reload on file save
Automatically refresh the SSA visualization and inlining decisions when you save your Go files.
Usage
Open a Go project in VSCode.
Open the Command Palette (Ctrl+Shift+P or Cmd+Shift+P on macOS).
