cubic offers both a free plan and paid subscriptions to fit every team’s needs.

​
How cubic works

Standard signups start with a 7-day free trial:
  • AI reviews included during the trial period
  • Full platform access to all features
  • No credit card required to get started
When your trial ends, you choose:
  • Continue free: Get 20 AI reviews per month with full platform access
  • Upgrade to paid: Get AI reviews with the same full platform access
Important: Regardless of which plan you choose, you always get complete access to cubic’s platform—PR management, analytics, notifications, and all features. Free plans have a fixed monthly AI review quota, while paid plans include a shared monthly AI review allowance across paid seats.

​
Free plan

Get started with cubic immediately—no credit card required:
  • Unlimited platform access: View and manage all your pull requests in cubic
  • 20 AI reviews per month: Get intelligent feedback on your most important PRs across all repositories
  • Full feature access: Analytics, code reviews, issue tracker integrations, background agents, and more;
  • Monthly quota reset: Your AI review limit resets on the 1st of each month
Perfect for personal projects, or evaluating cubic for your team.

​
How the free plan quota works

  • Organization-wide limit: The 20 AI reviews per month are shared across all repositories in your GitHub organization
  • Automatic tracking: AI review comments show how many reviews you have remaining
  • Monthly reset: Your quota automatically resets to 20 on the 1st of each month
For paid AI review access, cubic’s subscription cost is determined by the number of developer seats you choose to activate. Each active seat corresponds to a unique GitHub user within your organization. AI review usage on paid plans is measured in reviewed lines, with an allowance per paid seat that is pooled across your team.
  • Seat-based billing: You are billed based on the number of active seats you assign to your team members (GitHub users).
  • Flexible seat management: You can manage seat assignments at any time, both during your free trial and after it ends.
  • Customizable checkout: When you purchase a subscription, you select the exact number of seats you need.
  • Ultrareview: Pro plans include Ultrareview for high-risk or complex PRs. Ultrareviews count toward your team’s reviewed-lines allowance at 3× the standard rate.
  • Subscription management: Seat assignments and active seats can be viewed and managed through the subscription tab in your settings: https://www.cubic.dev/settings?tab=subscription

​
Flex capacity

Paid workspaces can use flex capacity to keep GitHub PR AI reviews running after included reviewed-line usage runs out. Flex capacity costs $30 per 10,000 extra reviewed lines and is billed only when cubic needs extra capacity for a review. Admins set a monthly spend limit in Settings → Subscription. cubic never spends past that limit; if the next required purchase would exceed the limit, reviews pause until you raise the limit or the billing period resets.

​
Automatic seat management

Admins can enable automatic seat management to handle team changes automatically. When enabled in your subscription settings, cubic will automatically assign and remove seats as your team changes. How it works:
  • When a new developer joins your GitHub organisation, they’ll automatically get a cubic seat. You’ll see this reflected in your billing.
  • If a developer leaves your organisation, their seat is removed and you’ll stop being billed for them.
Manual and automatic work together: You can still manually assign seats if you want. For example:
  • If you’ve already given seats to 3 out of 10 developers, and then turn on automatic assignment, the next (11th) developer who joins will automatically get a seat—bringing your total to 4.
  • This gives you flexibility to mix and match manual and automatic seat assignment, based on what works best for your team.

​
Bot seat management

​
Devin-bot support

cubic recognizes and provides special handling for automated coding assistants like Devin. When Devin opens a pull request in your repository:
  • Automatic detection: PRs authored by devin-ai-integration[bot] are automatically identified.
  • Dedicated bot row: Devin is assigned a bot row that’s kept separate from regular developer seats.
  • No paid developer seat: Enabling the bot allows its PRs to receive AI reviews without increasing your paid developer seat count.
  • Shared reviewed-line allowance: Bot-authored reviews use the same pooled reviewed-line allowance as the rest of your team.
  • No manual configuration needed: The system automatically creates and manages the Devin bot seat when it first contributes to your repository.
This feature ensures that teams using AI coding assistants can integrate them into their workflow without adding a paid developer seat for the bot account.

​
Free trial

During the free trial period, you can assign as many developer seats as you like to evaluate cubic with your team. When you choose a paid plan at checkout, billing starts immediately and is based on the number of seats you select. If you have any further questions about billing, please contact support.

cubic is automatically free for all public repositories. You don’t need to contact us or apply - just install cubic on your public repositories and start using it immediately at no cost. Very high-volume usage may be subject to fair-use limits.
When you increase seats, we calculate the unused portion of your month and charge only for the prorated difference. If you remove seats, your credit will apply to your next invoice.
Paid AI review usage is measured in reviewed lines rather than a fixed number of reviews.Your allowance is pooled across all paid seats on your team, so each paid seat adds to a shared monthly usage pool.Most teams never get close to these limits unless they are among the heaviest AI users.In practice, that means a 1- or 2-person team shipping a very high volume of code is more likely to approach the limit than a 20-person team, because the larger team has a much bigger shared pool.
Flex capacity is optional extra reviewed-line capacity for paid workspaces. It costs $30 per 10,000 extra reviewed lines, is charged only when a review needs more capacity, and stops at the monthly spend limit an admin sets. See Flex capacity for detailed examples.
Reviewed lines are the PR code changes cubic actually reviews, not repository size, total file size, or lines generated by AI. For most PRs, this means the added and deleted lines in the diff that cubic reads during review.Generated files, vendored code, binaries, ignored files, skipped files, and failed or cancelled reviews do not count. Incremental reviews only count newly reviewed changes; manual reruns count again. For more detail, see AI review usage and limits.
During your 7-day trial: You get AI reviews and full platform access.When your trial ends: You automatically transition to cubic’s free plan, which includes:
  • 20 AI reviews per month (resets monthly)
  • Unlimited platform access (same as trial)
  • All features remain available (analytics, PR management, notifications, etc.)
No interruption: You keep using cubic exactly as before, just with a monthly AI review limit. Upgrade anytime for paid AI review access with a larger shared allowance across paid seats.

In Settings → Subscription, admins have multiple ways to manage seat assignments:Individual management:
  • Toggle the switch next to any team member to assign/unassign their seat
  • Changes apply instantly
Bulk management:
  • Select multiple users with checkboxes
  • Use “Update seat status” dropdown to assign or unassign seats for all selected users
  • Perfect for onboarding new teams or managing large groups
Members and viewers can view the team list but cannot change seats or roles. Only admins see checkboxes and management controls.
cubic has three roles: Admin, Member, and Viewer.Admins can manage seats, change user roles, configure auto-assign settings, and manage billing. Members have full access to all cubic features and can manage non-billing settings, but they cannot change seats, roles, or billing details. Viewers can view cubic settings and review surfaces, but they cannot change settings, integrations, seats, roles, or billing details.The first user who creates an installation becomes an admin automatically. You need at least one admin per team, and admins cannot remove their own admin role. Bot accounts cannot be promoted to admin.See the Roles and permissions page for complete details.
cubic automatically detects and manages seats for recognized bots like Devin (devin-ai-integration[bot]). These bot seats are:
  • Created automatically when the bot first opens a PR
  • Not billed as developer seats when enabled
  • Disabled by default but can be enabled if you want the bot’s PRs to receive AI reviews
  • Counted against your normal reviewed-line allowance when their PRs are reviewed
  • Visible in your subscription settings alongside regular team members
This lets admins enable bot-authored PR reviews without increasing the paid developer seat count.
