How to choose the right AI code review tool

The best tool depends on what problem you're solving:

Auditing an existing codebase - Choose a full-codebase workflow like VibeRails. It is designed to review every file systematically with AI, not just incremental changes.
PR-level review automation - CodeRabbit or Sourcery integrate directly into your Git workflow with minimal setup.
DevSecOps platform - Codacy combines code review with coverage tracking, security scanning, and compliance in a single dashboard.
Test generation priority - Qodo specialises in AI-generated tests alongside code review.
Already using Cursor - BugBot adds basic PR review at no extra cost.
