Use the Auto model to make credits last, and only move up a tier once you know your monthly usage. | Stay on Free. The terminal is the product, and you can run Claude Code inside it on your Claude subscription without paying Warp anything. Only buy Build if you find yourself using Warp's own agent more than Claude Code. |
