Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Namespace

  • Developer plan is pay-as-you-go only; minimum usage unclear
  • Team plan $100/mo is competitive but usage limits may be tight
  • Devbox pricing separate at $0.004/minute could add up quickly
  • Enterprise plan requires custom sales conversation

TeamCity

  • Detailed pricing requires visiting a calculator and isn't transparent on the main pricing page.
  • Self-hosted setup and agent management require more operational overhead than fully managed CI/CD services.
  • Additional build agents and users are priced incrementally, which can add up for larger teams.
  • The UI and configuration model have a steeper learning curve compared to YAML-first CI tools.
