Pricing Comparison

CodeSandbox

Free

Users: 1 user

Storage: Limited

Limits: Limited credits, sandbox caps, no priority support, slower VM resources

Credit limits hit quickly for power users. 20 sandbox limit may require cleanup or upgrade.

Pro

Popular

$9/mo

Users: 1 user

Storage: More storage

Limits: Still credit-based, add-ons cost extra for more VMs

Credits still limited - heavy usage requires add-ons. Annual pricing required for best rate.

Builder

$119/mo

Users: Multiple users

Storage: Expanded

Limits: Expensive for individuals, designed for teams/enterprises

Massive jump from Pro ($9) - no intermediate option. May still need add-ons for enterprise scale.

Enterprise

$0/mo

Users: Custom

Storage: Custom

Limits: Unknown pricing, requires sales engagement

Contact sales required - no transparent pricing. Implementation and onboarding costs likely.

GitLab

Free

Users: 5 users per namespace

Storage: 5GB storage

Limits: 5 user limit, 400 compute minutes, no advanced CI/CD features, limited support

Very limited compute minutes, no premium support, limited security features

Premium

Popular

$29/mo

Users: Per user/month

Storage: 50GB storage

Limits: No DAST, no license compliance, no enterprise security features

Security scanning features (DAST, license compliance) require Ultimate upgrade, GitLab Duo Pro extra $19/user

Ultimate

$99/mo

Users: Per user/month

Storage: 250GB storage

Limits: Very expensive at scale, 242% more than Premium

Self-managed Ultimate even more expensive ($1,188/user/year), GitLab Duo extra
