CodeGraph: Interactive codebase dependency graph using tree-sitter and Neo4j

Original: Codegraph

Short summary

CodeGraph is a hackathon-built tool that parses codebases using tree-sitter and stores function call relationships in Neo4j AuraDB, rendering an interactive dependency graph. Users paste a GitHub URL to visualize which functions call which, and what breaks if a function changes. The stack includes Python, FastAPI, Next.js 15, and Neo4j, with a live demo available.

  • •Parses codebases with tree-sitter and stores call relationships in Neo4j
  • •Interactive graph shows what breaks when a function changes
  • •Live demo and open-source repo available for public GitHub repos
