| Which plan to pick | Start on the free Individual tier; it is the whole point. If you hit the weekly limits and you also use Gemini for other things, Google AI Pro at $19.99 is a sensible step. Ultra only makes sense for full-time developers. | Build on pay as you go, then add Core when you go live and want email support. HIPAA compliance is a separate $2,000-a-month add-on, so check that early if you work in healthcare. | 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. |
