I wish this could work with your monthly subscription where you get a flat quota in Antigravity with a free account / $20.
edit:
Is this not built out of VSCode? Isn't Antigravity based on VSCode? VSCodium has a Web build https://github.com/VSCodium/vscodium
UI wise it might be good to make it clearer you don't need to put in an API key to try it.
pretty sure i believe it violates ToS and will revoke your any Gemini/Antigravity access from your account.

I completely agree! Its so frustrating that providers (google, openai, anthropic) silo their $20/month consumer subscriptions away from their API access. It would be amazing if paying that flat fee gave you a 'personal API key' to use in open source UIs like this.
Unfortunately, we're stuck with standard API keys for now. Though I believe that google aistudio has decent free limits on gemini 3 flash with the free api keys? If you're just doing personal coding, you can easily plug a free api key into OpenGravity and basically use it as much as you want without paying a dime!
(I think its like 250 requests per day maybe?)
