A post titled "Google Antigravity TOS: 3rd party usage can get Google account suspended" reached 317 points and 211 comments on Hacker News, a discussion board for programmers, after it was shared on Twitter by Gergely Orosz.
The claim at the center of the post is specific: pairing Antigravity, Google's agent platform, with third-party tools can breach the terms of service in a way that gets the whole Google account suspended. For a developer whose Gmail, Drive and billing all sit under that one account, a suspension over agent usage would take out far more than the agent.
That is the tension a builder wiring Antigravity into their stack now has to weigh. A single revoked API key is a nuisance you fix in an afternoon. Losing the Google account behind it means losing email, file storage and whatever billing runs through the same login, all at once, over a usage question rather than a payment one.
The post does not say whether any developer has actually been suspended under this clause, only that the terms allow it. That gap, between what the terms permit and what Google has done in practice, is the open question a builder weighing Antigravity would want answered before they connect anything else to it.
211 comments on, that question is still open.
