| Which plan to pick | Try Pro for a month to see if the agents suit your codebase. If you want Droids working in the background while you do other things, you need Plus. | Pro is the sweet spot for an individual: cheap, unlimited autocomplete and enough credits for a few agent tasks a week. Only move to Pro+ if you find yourself buying extra credits every month. | 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. |
