What is CRG?

CRG (Better Code Review Graph) builds a knowledge graph of your codebase with semantic search and call-graph resolution, so AI code reviews use fewer tokens and understand how changes ripple through the code. It runs as an MCP server.

Third-party open-source projects. We are not affiliated with their authors; repositories are provided as-is by their maintainers. Review each project's license, code and security before installing. See our Disclaimer.

Pros: what CRG does well

  • Cuts tokens used in AI code reviews
  • Resolves call graphs across the codebase
  • Apache-2.0 licensed

Cons: where it falls short

  • Indexing takes time on large repos
  • Young project

Who CRG is for

Developers who use AI for code review on larger codebases.

Who can skip it

People with very small projects.
