01 / CALL GRAPH
Turn function relationships into a map.
Explore calls in both directions in the Hornet Graph panel. Pan and zoom while keeping the current function anchored, or change the center to follow another path.

Each graph loads up to 250 functions; change its center to explore larger call chains. Results depend on your project's parsing configuration.

This recording demonstrates the workflow. Available capabilities depend on your installed version.
Indexing and project scans
Recursively scans sources and headers, including generated and third-party folders, by default. Explicit Hornet exclusions define the boundaries. Progress appears as a percentage and file count.
Control background work
Adjust CPU settings, update or rebuild indexes, and open extension, Clangd and Hornet-DB logs from the status bar. Each local workspace keeps its own configuration and language services.
Try it on your project.
Stay in VS Code and bring it into your familiar workflow.
