Cubic

Code reviews are a major bottleneck for development teams, especially with the rise of AI-generated code. Cubic solves this problem by providing an intelligent code review platform that automates the first-pass review process.

Founded by Allis Yao and Paul Sanglé-Ferrière and backed by Y Combinator, Cubic helps teams like Cal.com and n8n ship code faster while maintaining high quality standards. The platform works by automatically reviewing pull requests when they're opened, learning from your codebase patterns, and providing actionable feedback directly in GitHub.

Instead of just showing you what's wrong, Cubic suggests specific fixes that you can apply with one click, making code reviews faster and more effective.

Cubic is an AI-powered code review platform designed to streamline the pull request process for software development teams. Think of it as having an expert code reviewer who understands your entire codebase and can spot bugs, security issues, and code quality problems instantly.

The platform integrates directly with GitHub and uses AI to analyze your code changes in real-time. Unlike generic code review tools, Cubic learns from your team's specific coding patterns, style guides, and past reviews to provide personalized feedback. It supports all popular programming languages including JavaScript, TypeScript, Python, Go, Ruby, Java, and C#.

The platform combines automated AI reviews with a human-friendly interface that makes manual code reviews faster and more efficient. Teams using Cubic typically see a 28% reduction in time from review to merge while catching more bugs before they reach production.

Getting started with Cubic is simple and requires no complex setup. First, sign up for a free account at cubic.dev using your GitHub credentials. The platform offers a 14-day free trial to test all features. Once registered, install the Cubic GitHub app with just two clicks to connect your repositories.

Here's how to maximize your experience:

The platform also offers a desktop app with keyboard shortcuts for faster navigation. For teams, you can assign licenses to specific developers rather than purchasing for everyone. The AI learns from your feedback over time, becoming more accurate and relevant to your codebase.
