| Which plan to pick | Start with the 14-day trial. Essentials is enough for most small teams; you only pay for developers who open pull requests. Turn on usage-based reviews ($0.25 a file) with a monthly cap if you keep hitting the hourly limit. | Pro at $20 is the place to start, and you get $20 off your first paid month when you upgrade. Use the Auto model to make credits last, and only move up a tier once you know your monthly usage. | Personal. If you have Claude Pro, run Claude Code inside Zed and you are done. Pro only makes sense if you want Zed's built-in assistant and edit predictions without setting up API keys. |
