Google blocks Antigravity for OpenClaw-linked AI Ultra users, cites “malicious usage”

by

New Delhi: Paying Google AI subscribers say they got locked out of Google’s “Antigravity” access after linking their accounts to third-party tools like OpenClaw and OpenCode. The reports say the disruption started for many users in the last week or so, then turned into a louder wave of complaints around February 12 to 14, as 403 PERMISSION_DENIED errors began showing up in Google’s support forums and on Reddit.

What stung people most was the suddenness. Users, including paying $250 a month Google AI Ultra subscribers, say they saw a blunt message on their accounts: “This service has been disabled in this account for violation of Terms of Service,” and they did not get a warning email, a grace period, or a clear appeal route. As of Monday, Feb 23, the posts are still circulating.

What users say triggered the lockouts

Based on the reports shared online, a common pattern keeps popping up. Users were on Google AI Pro or Ultra plans. They connected those accounts through OpenClaw or similar tools. Then Google detected the usage and “disabled Antigravity access.”

People are also linking the failures to one specific setup: using Antigravity OAuth tokens inside OpenClaw. That is where the same error keeps showing up again and again, according to the forum and Reddit posts mentioned above.

Google’s policy angle and the “malicious usage” label

The core issue, as described in the reports, is a policy violation tied to “malicious usage.” The claim is that Google’s Antigravity backend is meant for first-party services. When third-party tools route requests through private OAuth tokens, Google’s systems can flag it as abuse or as a way to get around standard API limits.

Google’s side has also surfaced publicly through a post on X. Varun Mohan said they had been “seeing a massive increase in malicious usage of the Antigravity backend that has tremendously degraded the quality of service” for legitimate users. He added they needed to “quickly shut off access to these users that are not using the product as intended.” He also said there is “a path for unaware users to potentially regain access.”

OpenClaw creator calls the ban wave “pretty draconian”

Peter Steinberger, the creator of OpenClaw, described the Google ban wave as “pretty draconian”. He said he will remove support for Antigravity from the tool and warned users to be careful if they plug it in.

That one line matters, since it hints this was not a small glitch. It reads like a hard stop, not a temporary outage.

What affected users can check right now

If you are trying to figure out if you are in this bucket, the reports point to a few common signs:

  • A sudden “disabled for violation of Terms of Service” notice
  • 403 PERMISSION_DENIED errors after linking via OpenClaw
  • Antigravity OAuth tokens being used inside third-party tools

No one likes getting a ban screen after paying. Still, this looks like a policy enforcement story, not a billing error story.

What alternatives are there?

If you are an OpenClaw user leaning on Antigravity, the community’s message is simple. Stop and switch. OpenClaw’s official guidance is to stick to API keys instead of OAuth tokens. People are also sharing workarounds and plan B options. Names like MiniMax and OpenAI’s Codex keep coming up as alternatives that users see as less risky, mainly since they do not tie into Google account access in the same way.
