Code Review Graph for VS Code

Visualize code dependencies, blast radius, and review context from your code graph -- directly in VS Code.

Features

Code Graph Explorer -- Browse files, classes, functions, and their relationships in a tree view
Blast Radius -- See which files and symbols are impacted when you change code
Review Changes -- Automatically detect git changes and show their blast radius
Find Callers -- Trace all callers of any function
Find Tests -- Locate tests for any symbol
Interactive Graph -- Force-directed D3.js visualization of your code dependencies
Live Search -- Fuzzy search across your entire code graph with instant results
Auto-Update -- Graph rebuilds in the background when you save files

Install Code Review Graph from the VS Code Marketplace.

The extension requires the code-review-graph Python CLI to parse your codebase.

# Recommended
uv pip install code-review-graph

# Alternatives
pipx install code-review-graph
pip install code-review-graph
