A CLI tool that generates interactive function call graphs for navigating unfamiliar codebases
Developers who inherit or join a new codebase spend days tracing execution paths manually through an editor, with no fast way to see how functions connect. Existing solutions are either full IDEs (Windows-only, paid, not CLI) or structural search tools that cannot show call graphs. This tool indexes a codebase once, then lets you trace callers and callees from any entry point via a fast CLI with exportable graph output.

Gap Assessment
3 tools exist (Source Insight, ast-grep (sg), CodeGraphContext) but gaps remain: Windows-only, paid GUI application, no CLI, no open API, no multi-language LSP integration, no export to standard graph formats; No call-graph construction or visualization, cannot answer 'what calls function X' or 'what does Y call', search only.

Competitive LandscapeFREE
| Product | Does | Missing |
|---|---|---|
| Source Insight | Feature-complete code navigation with call graphs and symbol browsing | Windows-only, paid GUI application, no CLI, no open API, no multi-language LSP integration, no export to standard graph formats |
| ast-grep (sg) | Structural pattern search across codebases using AST matching, fast CLI | No call-graph construction or visualization, cannot answer 'what calls function X' or 'what does Y call', search only |
| CodeGraphContext | MCP server plus CLI that indexes local code into a graph database, traces callers and callees across files | MCP-server framing targets AI agent context injection, not interactive human developer navigation; no interactive graph UI, no per-team sharing, no CI integration |
