Backend Code Review

langgenius/dify
1.7k installs151.8k stars
Summary

This is a structured code reviewer for Python backend files under your api directory. It catches the usual suspects like SQL injection, N+1 queries, and hardcoded secrets, but the real utility is in the domain-specific rules for database schema design, SQLAlchemy patterns, and repository abstraction. It handles three modes: reviewing pending changes, pasted snippets, or specific files you point at. Output is organized into critical issues, suggestions, and nits with file locations and code examples. The checklist approach means you get consistent reviews based on actual architectural rules rather than generic linting. Worth using if you have a FastAPI or Flask project with SQLAlchemy and want enforcement of layering patterns.
