Starts at Free · 5.0/5 from 1 reviews
Good value

Claude Code is not a second seat.

Strengths

  • +Lives in the terminal and in the editor, so it can edit files, run tests, and handle git without a separate chat window
  • +Included on every paid Claude plan, not a second coding seat

  • +Opus Fast mode is documented at significantly faster speed for heavier sessions

Weaknesses

  • -Console / API billing is a second meter if you leave the subscription path
  • -Fast mode costs more per token than default Opus
