Codeflowmap – Data Flow Analyzer for Codebases

A developer tool that maps code dependencies, call graphs, and data flows (read/write/auth paths) in a repository. Helps engineers understand complex codebases, especially AI-generated code. Point it at a repo and visualize what touches what.

Static analysis and code visualization have renewed urgency as AI-generated code floods codebases that no single engineer fully understands — teams are shipping faster than they can reason about what they've built. Sourcetrail was the closest dedicated tool in this space but was abandoned and open-sourced in 2021, leaving a real gap; IDE plugins like CodeSee partially fill it but lack depth on auth and data-write path tracing specifically. The $2k–10k/mo revenue band is realistic for a prosumer devtool if priced per seat or per repo at $20–50/month, since engineering teams will pay for anything that cuts onboarding time or security review time — both measurable costs. The biggest risk is that the major IDEs (VS Code, JetBrains) or GitHub itself ships a native version of this, which they have obvious distribution advantage to do and have already been moving toward incrementally.
