Antigravity: Third-Party Use Could Suspend Your Whole Google Account

A warning posted on 3 September 2026

On 3 September 2026, Gergely Orosz went public with a warning about the terms of service for Antigravity, Google’s development tool. According to his post, those terms spell it out plainly: if Google decides you’re using Antigravity in a way it suspects is third-party use — the example given is OpenClaw — the company can suspend your Google account. His conclusion fits on one line: “One reason to NOT use Antigravity.” He adds that he isn’t taking the risk.

One caveat up front: this rests on a single source, a public post relayed on Hacker News, and it doesn’t quote the terms themselves. So read everything that follows with the word “reportedly” hovering over it.

Getting banned costs more from some vendors than others

Nineteen hours earlier, Theo (t3.gg) was making a neighbouring point: using your Gemini subscription outside Google’s official surfaces would reportedly put your entire Google account at risk of a ban. And he draws the comparison that stings: getting banned by OpenAI or Anthropic is annoying; getting banned from your Google account is a different species of problem entirely.

The logic holds without needing a single number to back it up. An OpenAI or Anthropic account is a subscription. You cancel it, you open one somewhere else, you paste your prompts back in, and your afternoon continues. A Google account, for a lot of people, is the email address that every other login answers to, plus the phone, the backups, the calendar you share with your employer. One is a bad afternoon. The other is rebuilding your digital life from a shoebox of paper receipts.

The blast radius of a dev tool

What this episode is really about goes well beyond Antigravity. Until now, the worst a vendor could do to you over disputed usage was take the tool away. Here, the tool and your identity hang off the same account: the penalty doesn’t stop at the offending product, it climbs back up to the keyring that opens everything else. The asymmetry is something to behold — you’d be accepting a hard-to-undo risk to your identity in exchange for a convenience your vendor can undo any time it likes.

The detail that really smarts is the verb in the warning: Google suspects. Not observes. Not demonstrates. Reserving the right to act on a technical hunch, with your entire suite of services as the blast radius, is an awful lot of trust to ask for in return for what is, at the end of the day, a code editor.

What the source doesn’t tell you

A great deal, honestly. The exact passage from the terms isn’t quoted. We don’t know which signals would trigger a suspicion of third-party use, whether there’s a warning first, or whether any appeals process comes attached to a suspension. No account has actually been reported suspended on these grounds. What we have is one worried developer reading the fine print carefully — a useful stage, but not a proven one.

Until Google clarifies where it actually stands, the question to ask before you install the thing isn’t “does it write good code?” but “what do I lose the day the account goes?” For a handful of faster autocompletes, that’s a steep deposit to put down.
