Frequently Asked Questions

Architecture and operational details for Callscope

Callscope uses a two-pass static analysis with Python's standard `ast` library. It first collects all functions, methods, classes, and raw call sites, then intelligently resolves call edges. The resolved graph and source snippets are embedded into a single HTML file for interactive, client-side rendering and navigation.
