|---|---|---|---|
| Plans | Free Free Open-source projects and trying it out. | IndividualOur pick Free Trying agent-based coding without paying. | PersonalOur pick Free Almost everyone. |
EssentialsOur pick $24/dev/mo billed yearly, or $30 monthly Small teams who want every pull request reviewed. | Google AI Pro $19.99/mo People who already have or want the Google AI Pro bundle. | Pro $10/mo People who want Zed's hosted AI without managing keys. | |
Team $48/dev/mo billed yearly, or $60 monthly Busier teams with many open pull requests. | Google AI Ultra From $99.99/mo Developers who want Antigravity as a daily driver. | Business $30/seat/mo Teams that need spending and access controls. | |
Advanced $72/dev/mo billed yearly, or $90 monthly Teams that want security monitoring. | Business (via Google Cloud) From $30/seat/mo Companies already on Google Cloud. | ||
Enterprise Custom Large organisations. | |||
| 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. | 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. | 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. |
