Which plan to pickStart 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.Start free to test, then top up $10 to $20 of credit on Pay as you go. That alone lifts the free-model limit to 1,000 requests a day. Only look at Business if you have a legal reason to keep data in a region.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.

Pros and cons

AttributeGoogle AntigravityOpenRouterZed
Pros
  • Free tier is good enough for real projects
  • Agent manager and verification artifacts make reviewing AI work easier
  • Browser agent tests your app, not just the code
  • Included with Google AI Pro, which many people already pay for
  • One key and one bill for nearly every model worth using
  • No markup on model prices, only a small fee on top-ups
  • Fallbacks and routing keep apps running when a provider fails
  • Free models and launch-day access make it cheap to experiment
  • Good privacy defaults, with no prompt logging unless you opt in
  • Noticeably faster than VS Code and Cursor
  • Free, open source, and no charge for running your own agents
  • Clean agent panel that shows exactly what changed
  • Built-in real-time collaboration
Cons
  • Free limits have been cut before and could change again
  • Capacity errors at busy times on the free tier
  • Tied to Gemini models, so you cannot bring Claude or OpenAI
  • The product has been renamed and reorganised more than once this year
  • Output quality and speed depend on which provider serves the request, and some hosts are noticeably worse
  • Free models are rate limited, often busy and throw 429 errors at peak times
  • Unused credit can expire after a year and refunds are only offered within 24 hours
  • Support is slow by most accounts, and Trustpilot reviews are poor (about 1.6 out of 5)
  • It is an API tool first, so non-technical users get little beyond the basic chat room
  • Smaller extension library than VS Code or Cursor
  • Less hand-holding for beginners; it assumes you know your way around an editor
  • Business plan has no SSO yet, which rules it out for some companies
  • Its own hosted AI is basic compared with the agents you can bring
