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

JetBrains Rider

  • Requires a paid subscription with no permanently free commercial tier.
  • Heavier resource usage than lightweight editors like VS Code for small projects.
  • Some advanced features overlap with a separate ReSharper Visual Studio plugin, causing licensing confusion.
  • First-year pricing increased in late 2025, raising the cost of entry versus prior years.
