Spec score 9.3 #2 of 50 in Code review software

What it is

Cubic reviews pull requests with AI and scans codebases for bugs and security issues. It checks proposed changes against the wider codebase and team rules, including possible effects on other code, and learns from senior developers’ past comments and team feedback. The workflow can auto-approve low-risk pull requests, assign a merge confidence score from 1 to 5, and let coding agents fix findings. Cubic supports GitHub, including GitHub Enterprise Cloud; GitHub Enterprise Server, GitLab and Bitbucket are not supported yet. It describes itself as language-agnostic and lists JavaScript, TypeScript, Python, Go, Ruby, Java and C# among supported languages. Starter Free allows 20 reviews a month for public repositories. Team costs $30 a month billed yearly per developer; Pro is 79.00 USD and Max is $160 a month, also billed yearly per developer. For pull requests with more than 200 eligible files, Cubic selects up to 200 for review. Reviews pause after a team exceeds its line allowance unless an admin enables flex capacity at $20 per 10,000 extra lines.

Cubic in depth

Read the full write-up

Cubic is an AI code-review and codebase-scanning service for GitHub teams. It is best suited to teams that want reviews shaped by repository context and their own rules. Its workflow controls and adjustable review behavior are appealing, but per-developer line allowances and GitHub-only hosting are meaningful constraints.

Overview

Cubic reviews pull requests against the broader codebase and team rules, so its remit includes potential effects beyond the changed files. It also scans codebases for bugs and security issues. Review suggestions can be informed by senior developers’ past comments and team feedback, a useful way to align automated review with established team practices.

There is a scope ceiling for especially large changes: when a pull request has more than 200 eligible files, Cubic reviews up to 200 of the highest-priority files. Teams should not rely on it to cover every eligible file in a very broad pull request.

Key features

Context-aware AI review: Using codebase context and team rules can help identify risks that a diff-only review might miss. The feedback loop from past comments and team responses makes this a better fit for teams with discernible review conventions than for those seeking a fixed, one-size-fits-all checker.

PR workflow controls: Cubic can auto-approve low-risk pull requests, assign each PR a merge confidence score from 1 to 5, and let coding agents fix findings. Those options support a more automated workflow, though teams still need to decide how much autonomy is appropriate.

Language and integrations: Cubic describes itself as language-agnostic and names JavaScript, TypeScript, Python, Go, Ruby, Java, and C# among supported languages. The pricing page lists Jira, Linear, Asana, and Notion integrations; Confluence and MCP are available on certain paid plans.

Security and data handling: Cubic says it is SOC 2 Type I compliant, encrypts data in transit with TLS 1.2+ and at rest with AES-256, and bars its AI providers from training on customer code. Reviews run in isolated containers, with AI processing the PR diff and only the context needed for review. These are relevant safeguards for teams assessing code access, though they do not change the Git hosting restriction.

Pricing

Cubic is freemium, with paid plans from $30/mo (annual). The per-developer line allowances make seat count and expected review volume central to budgeting; exceeding the allowance pauses reviews unless an admin enables flex capacity.

Starter Free — free: Includes 20 PR reviews a month and is free for public repositories. It is a way to assess the workflow on public code, but the monthly review cap is not a broad free allowance for private-team use.

Team — $30 a month (billed yearly; $30 per developer / month): Includes 40k reviewed lines per developer, 5 custom review agents, 5 private wikis, PR and CLI reviews, and Jira, Linear, and Asana. It suits teams needing private workflows and integrations, but the per-developer quota can constrain heavy review use.

Pro — $79 a month (billed yearly; $79 per developer / month): Raises the allowance to 80k reviewed lines per developer and includes 10 custom review agents, codebase scans for 3 repos, premium support, and a shared Slack channel. It is the more suitable tier for teams that need repository scans and closer support, at a substantial per-developer premium.

Max — $160 a month (billed yearly; $160 per developer / month): Includes 160k reviewed lines per developer and every Pro feature. The larger allowance is aimed at teams whose review volume exceeds Pro’s; teams that do not need that capacity may not benefit from the higher price.

Enterprise Custom — custom pricing: Includes SSO/SAML, audit logs, custom terms, and custom review limits, with dedicated support. Contact [email protected] for pricing. This is the tier for organizations requiring those controls and terms rather than a fixed self-serve package.

When a team exceeds its reviewed-line allowance, reviews pause until the next billing period unless an admin enables flex capacity at $20 per 10,000 extra lines, up to a configured monthly limit. That offers a controlled way to handle bursts, but teams should account for the add-on or expect review interruptions.

Platforms

Cubic supports API, Linux, macOS, web, and Windows. Desktop builds are offered for macOS Apple Silicon, macOS Intel, Windows, and Linux, and the service is also available on the web. Hosting support is narrower than the platform list: Cubic supports GitHub, including GitHub Enterprise Cloud, but not GitHub Enterprise Server, GitLab, or Bitbucket.

Who it's for

Cubic is a strong candidate for GitHub teams that want codebase-aware PR reviews, review behavior tuned by team feedback, and automated workflow options. It is less suitable for teams on GitLab, Bitbucket, or GitHub Enterprise Server, and for organizations whose largest pull requests regularly exceed the 200-file review ceiling. Per-developer quotas also make expected line volume an important fit check before choosing a paid plan.

Pros and cons

Pro: Reviews draw on codebase context and team rules, addressing potential downstream effects rather than only the edited lines.

Pro: Team feedback and senior developers’ prior comments can shape suggestions, while low-risk auto-approval and merge confidence scoring add workflow controls.

Pro: Pro includes codebase scans for 3 repos, and Enterprise offers SSO/SAML, audit logs, custom terms, and dedicated support.

Con: GitHub is the only supported host; teams using GitLab, Bitbucket, or GitHub Enterprise Server cannot use Cubic for those repositories.

Con: Reviews cover at most 200 highest-priority eligible files in a pull request with more than 200 eligible files.

Con: Line allowances are per developer, and reviews pause after quota exhaustion unless flex capacity is enabled, adding either interruption or extra cost.

Alternatives

For another option, compare AI Code Review Tools and Code review software. Consider CodeRabbit if its free reviews for public repositories or broader platform range, including self-hosted and extension, better fits your setup. ThinkReview is worth comparing if a $10 a month Lite plan with 15 review credits per day and support for PRs up to 40,000 lines suits your usage. DeepSource may fit teams prioritizing unlimited public repositories, unlimited team members, and 1,000 pull request reviews per month on its Open Source plan. Choose Ironwood AI if you want a 30-day evaluation with two developers and full Professional features. Bito is an alternative to compare for its $12 a year AI Code Reviews Team plan, which includes 5K lines per seat per month. Gitar offers a free-for-open-source plan for qualifying public GitHub or GitLab repositories with an OSI-approved license. LiveReview is another freemium option to consider. CodeAnt AI may suit buyers looking for a 14-day free trial without a credit card.

Verdict

Choose Cubic if your team uses GitHub and wants pull-request reviews informed by codebase context, team rules, and reviewer feedback, with scans and workflow automation available as needs grow. Look elsewhere if you need another Git host, complete review coverage for very large pull requests, or allowances that do not scale with developer seats and reviewed lines.

Verdict

Cubic provides context-aware AI review and codebase scanning for GitHub teams. Review the hosting limits and line allowances against your workflow before selecting a plan.
