Crabviz is a LSP-based call graph generator. It leverages the Language Server Protocol to generate interactive call graphs, helps you visually explore source code.

• Workable for various programming languages

• Highlight on click

• Two kinds of graphs

  You can generate a call graph for selected files to get an overview, or for a selected function to track the call hierarchy.

• Collapse Files to view file relationships

• Save call graphs as HTML or SVG

• Go to definition

• Search symbols

Since Crabviz utilizes the capabilities of language servers, it is better suited as an IDE/editor extension than a standalone command line tool.

It is currently available on VS Code, and PRs for other editors are welcome.

Crabviz is inspired by graphql-voyager and go-callvis.
