cubic Overview

cubic is an AI-native code review platform designed for modern software teams to accelerate their development lifecycle and enhance code quality. By integrating directly with GitHub, cubic automates the tedious parts of code review, allowing developers to merge pull requests (PRs) up to 28% faster and ship code 3 times faster. It acts as an intelligent assistant, providing instant, insightful feedback on every PR.

The platform is built with a deep understanding of software development workflows. It goes beyond simple linting to analyze the context of code changes, identify potential bugs, security vulnerabilities, and deviations from best practices. Trusted by hundreds of engineering teams, from fast-growing startups to large enterprises, cubic helps streamline collaboration and allows senior engineers to focus on high-level architectural decisions rather than routine checks.

How to use cubic

Getting started with cubic is a straightforward process designed for quick integration:

Connect to GitHub: Simply connect your GitHub account to cubic. The integration process is seamless and takes only a few minutes.
Automatic Reviews: Once connected, cubic automatically starts reviewing new pull requests in your repositories. It posts comments directly in the PR, just like a human reviewer.
Review Feedback: Developers receive inline feedback within seconds of opening a PR. The comments cover bugs, logic errors, security risks, and style guide violations.
Apply Fixes: For many of the issues it identifies, cubic offers one-click fixes. This allows developers to resolve problems instantly without manual refactoring.
Customize Rules: Teams can configure cubic to enforce their specific coding standards, style guides, and best practices by creating custom rules. The AI also learns from your team's existing comment history to adapt to your unique context.
