cubic
Beanspruchencubic is an AI code review platform for complex codebases. Catch bugs in pull requests and scan repositories for issues before merge or release.
What cubic is
cubic is an AI code review platform for complex codebases. It reviews pull requests, scans repositories for bugs and vulnerabilities, and helps teams move from detection to triage and fix with less manual review work.
The product focuses on two related workflows: PR review in GitHub and IDEs, and deeper codebase scans that run on a schedule or before a release. It also connects to common team tools so reviews can use surrounding context from the rest of the engineering workflow.
Core capabilities
PR summaries and descriptions
Generates AI PR descriptions that summarize the change and highlight impact so reviewers can understand the diff faster.
Custom review rules
Lets teams define standards in plain English and learn from senior developers’ comment history so reviews can reflect team conventions.
Continuous codebase scanning
Runs codebase scans with thousands of AI agents to look for bugs and security issues across the repository, not just the current diff.
Triage and automated fixes
Creates tickets, notifies issue owners, and can open fix PRs with background agents or coding agents when problems are found.
Supporting workflows
Provides AI wiki capabilities and a CLI on supported plans, with options for contextual searches, usage analytics, and integrations with workplace tools.
Where cubic fits
PR review before merge
Use cubic on incoming pull requests when you want inline review comments, faster summaries, and help catching bugs before merge.
Ongoing codebase scanning
Run scheduled scans to surface bugs and vulnerabilities in a repository, then assign issues, create tickets, or open fix PRs.
Team-specific review workflows
Use the product when your team wants review rules and context from tools like Jira, Linear, Asana, Notion, or Confluence to influence comments.
High-velocity teams
Adopt cubic in an engineering organization that ships frequently and wants to reduce review bottlenecks without ignoring code quality.
Public repo maintenance
Apply it to public repositories or open-source projects where the site says cubic is free and review volume still matters.
