Kilo Code Reviewer

What is Kilo Code Reviewer?

Kilo Code Reviewer is an AI-powered tool that automatically analyzes pull requests, catches bugs, suggests improvements, and enforces code quality standards before code gets merged. It integrates directly with GitHub and GitLab, offering over 500 AI models—including Claude, GPT, Gemini, and several free options—to deliver instant, actionable feedback. The tool is now available for free, with unlimited reviews using Kilo Auto or a free model, and requires no credit card to start.

Who it's for

• Individual developers who want to catch bugs and security flaws in their code before committing or opening a pull request
• Engineering teams looking to enforce consistent coding standards and reduce the burden on human code reviewers
• Open-source maintainers who need scalable, automated review processes across many contributions without added overhead

Key features

AI model selection and flexibility

Choose from over 500 models, including Claude 4 Opus for deep analysis, Gemini 2.5 Pro for routine reviews, and several free options. You can mix and match models based on pull request complexity, balancing thoroughness with cost.

Local IDE review

Before committing, run a code review directly in VS Code or JetBrains. The AI analyzes uncommitted changes for bugs, security vulnerabilities, and quality issues, allowing you to fix problems on the spot and commit with confidence.

Custom review style and instructions

Set your review to strict, balanced, or lenient, and focus on specific areas like security, performance, bugs, code style, test coverage, or documentation. Add custom instructions so the AI learns your team's coding standards and architectural patterns over time.

Inline PR feedback

Receive inline comments on pull requests with specific suggestions, explanations, and code examples. Issues are flagged before human review, helping teams address problems early and ship faster.

What stands out

"It was the only code reviewer that identified a security flaw in my project. I usually have two code reviewers, Copilot and Gemini. The Kilo Reviewer completed its review before both of them and discovered an injection vulnerability."

This real-world testimonial from a developer highlights Kilo Code Reviewer's ability to catch critical security issues that other AI tools miss—and do it faster. Combined with its free tier, 500+ model support, and local IDE review capability, it offers a uniquely flexible and thorough approach to automated code review.

Worth checking out if…

You're a developer or engineering team that wants to catch bugs and security vulnerabilities earlier, enforce coding standards consistently, and reduce the time spent on manual code review. Kilo Code Reviewer is especially useful if you value model choice, need free unlimited reviews, or want to review code locally before it ever reaches your repository.
