Which plan to pickStart 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.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.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.

Cons
  • Marketed as unlimited, but hourly caps and fair-use throttling frustrate heavy users
  • Can be noisy, with nitpicks mixed in with real problems
  • Per-developer pricing adds up for bigger teams
  • Some users report billing mistakes, refund trouble and slow support
  • Rolling usage limits make monthly cost hard to predict, and premium models eat them fast

  • Only useful if you have developers to review its work
  • Free limits have been cut before and could change again
