Present AI coding agent changes as a dependency map instead of a line-by-line diff

Problem

AI coding agents can touch dozens of files at once, making traditional diffs hard to assess impact and logic. A Show HN post specifically built a tool to review changes as a map rather than a diff, confirming this new pain point in the AI coding era.

Solution

Parse git diffs and code call relationships to generate a module- or function-level dependency change graph, highlight affected paths, and let users click nodes to see the underlying diff. Support major languages and frameworks.

Users

Developers using Cursor/Copilot/Claude Code, code reviewers, tech leads

MVP

Connect to a git repo and parse diffs; build a file- and function-level call graph; mark changed nodes and impact scope on the graph; click a node to expand diff details; support shareable export links

Revenue

Free tier limited by repo count and monthly reviews; Pro subscription for private repos and team collaboration; per-seat pricing

Why now

AI-generated code volume is exploding, and diff-based review no longer matches the cadence; indie developers can build an MVP quickly with tools like tree-sitter
