Local Code Index & Call Graph

Interactive call graphs for large repos without LLM

Problem

Developers struggle to navigate large codebases and quickly understand function call relationships; existing tools rely on LLMs or cloud, which are slow and raise privacy concerns.

Solution

A local tool that statically analyzes codebases, generates call graphs, and visualizes them; supports fast jump and search, fully offline, no LLM needed.

Users

Developers working with large codebases, engineers maintaining legacy systems.

MVP

Support major languages (Python, JS, Go); generate call graphs; search and jump; CLI and simple web UI.

Revenue

Free open-source core, paid enterprise features (multi-repo, team collaboration, CI integration); or one-time purchase.

Why now

Codebases are growing, LLM cost and privacy concerns rise; static analysis tools are mature, indie developers can build quickly.
