Looking for the AI code review tools worth trying this year? This guide covers 7 tools listed on TrendingDevTools, with what each one does, who it suits and its pricing or free tier, checked on each vendor's own site in October 2026.
Every tool here is listed on TrendingDevTools. We read each vendor's own website and pricing page for the plan details below. Where a vendor does not publish a number, we say so instead of guessing. Prices can change, so check the vendor's site before you buy.
CodeRabbit is an AI code review tool that reviews pull requests and also works in the CLI and IDE.
Greptile is an AI code reviewer that understands your whole codebase and reviews pull requests with that context.
Qodo is a code quality platform focused on AI code review in pull requests.
GitHub Copilot is GitHub's AI pair programmer that works inside VS Code, JetBrains IDEs, Visual Studio, Xcode and more, plus on GitHub itself.
SonarQube is Sonar's code quality and security platform that checks bugs, vulnerabilities and security hotspots across 30+ languages.
Snyk is a developer security platform that scans code, open-source dependencies, containers and infrastructure as code.
Semgrep is a code security platform for static analysis (SAST), supply chain checks and secrets detection.
AI code review uses language models to read pull requests and leave comments on bugs, security issues, style and logic, before a human reviewer looks.
Greptile has a free Starter plan for one developer with 50 credits per month, and SonarQube and Snyk both have free plans.
No. AI reviewers catch many issues quickly, but a human should still check design decisions and business logic.
Static analysis tools like SonarQube and Semgrep check code against rules. AI reviewers like CodeRabbit and Greptile read changes in context and explain issues in plain language. Many teams use both.
