Best AI Tools for Code Review in 2025
AI-powered code review and quality analysis tools
Windsurf
The AI IDE that writes code with you
💡 Expert's Tip:
Cursor's most serious rival. The Cascade agent handles multi-file edits better than most tools. Free tier is genuinely useful, not crippled.
Aider
AI pair programming in your terminal
💡 Expert's Tip:
The hacker's AI coding tool. Bring your own API key, run in terminal, commits to git automatically. If you live in the terminal, this is underrated.
Cody by Sourcegraph
AI coding assistant with your entire codebase as context
💡 Expert's Tip:
Kills it for large-codebase navigation. If you've ever asked 'where is X implemented?' across 500k LOC, Cody earns its place. Overkill for small projects.
