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.

GitHub Codespaces

Free (Personal)

Free

Users: 1 user

Storage: 15 GB

Limits: 120 hours/month cap, 2-core machines only, personal use

Hours run out for active developers. Storage billed even when suspended. Billing issues can block access.

Pro/Team

Popular

$0.18/mo

Users: Multiple users

Storage: Variable

Limits: Pay-as-you-go can be expensive, hourly billing complexity

Compute: $0.18/hr (2-core) to $2.88/hr (32-core). Storage: $0.07/GB/month. Costs accumulate fast with large teams.

Enterprise

$0/mo

Users: Custom

Storage: Custom

Limits: Unknown pricing, requires GitHub Enterprise

Enterprise GitHub pricing plus Codespaces usage. Contact sales for pricing. May require annual commitment.
