Free-plan checks

  • Run each free tool on the same bug fix or refactor and compare the final diff, test output, and review effort.
  • Check whether repository access, command execution, chat history, and generated code can be controlled.
  • Upgrade only when the paid plan reduces real reviewer time or safely handles larger repositories.

Upgrade rule

Do not upgrade because a tool looks impressive in a demo. Upgrade only when the free tier blocks a repeated workflow, creates licensing risk, or fails quality checks on real work.
