heey please please fix this issue as soon as possible!! can’t get any work done. It keeps occurring all day, and wastes all my credits on this error. Same issue still happens on all version…
Issue is now occurring for Gemini Flash as well despite being on the Ultra plan. Previously, this issue was resolved by upgrading to the latest build, and it was limited to Opus models only. Currently, it impacts all models, and there is no newer build available to upgrade. Below is debug info

Also, I might have lost credits too due to this because overages are enabled in my editor.

It seems that there are a lot of these thread messages popping up. Even on Google Antigravity Status. Check if Google Antigravity is down or having an outage. | StatusGator - it appears that everyone regardless of which Google AI Ultra subscription one is on are all experiencing a similar experience.
Google doesn’t deserve to have users like Kiro anymore, it’s time to kill Antigravity. Codex, Claude Code, and Cursor have already won, even Cursor is better, and I use all four, but I cut Antigravity and came back to test it this month and it’s the same crap.
A WARNING FOR ANYONE ELSE SEEING THIS ISSUE: RISK OF GOOGLE ACCOUNT BEING DELETED:
I reached out to google one support about this, they told me my account was restricted from antigravity due to there being ‘non-antigravity’ tools, something something ToS: I am using the most updated version of your software, i have some extensions but they are only ones i got on your marketplace. they told me if i submit an appeal and its denied my entire google account will be deleted, which would pretty much destroy my life right now as i depend heavily on gmail, drive, etc for work; school, all of it. I am stuck and have no real solution. I am 100% certain this is a bug, and its seemingly like many others are experiencing this. This is the normal antigravity downloaded from your official site, and only extensions added from your marketplace. This is definitely a false positive, and I only reached out because i also saw the high traffic error over and over. I am not sure what to do other than wait and hope this is resolved, but i also wanted to comment here in case others are experiencing the same thing. I dont want to send an appeal because if theres an error in the system someone will see that flag and delete my account; that would be detrimental. hopefully others experiencing this can provide insight as to whats going on, i wont submit the appeal, but I do need access and have lots of work to do. Any guidance is appreciated. Please let us know any updates about this issue. let us know any basic things we should do to try to identify the cause of the flag if its something we can avoid; but I am using the provided antigravity software, using marketplace provided extensions, and on the ultra plan.
Thank you anyone who can offer guidance. Bit anxious about this as its at a very busy time, and the google one plan is important for many reasons including just logging in to important accounts, many many years of drive files, etc. I never do anything against ToS, with absolute 100% certainty. All i saw was the high traffic error, reached out, and this is what i was told.

Upon checking on our resources, your access to Antigravity has been restricted because the system detected that Antigravity servers were being used to power a non-Antigravity product. This falls under a zero-tolerance policy within the Google Terms of Service. Access to this specific platform has been restricted, but you can continue to use your Google One storage and other plan benefits.

I dont even understand what this could be talking about. I have zero idea, other than maybe an extension i installed; but i installed it from the antigravity marketplace. If the marketplace has tools that are against ToS then that would need to be addressed because I don’t see how we can then tell the difference between trusted parts of the software and ones that are not; but as far as I can tell all my extensions are quite normal. Nothing that would even smell fishy. I read the ToS extensively and cross-checked things with an LLM for sanity. Nothing seems off. I am almost certain this is a bug, something flagging our accounts erroneously.
Thanks. this was posted in panic while im mid support chat, wanted to get something out to help anyone else in this situation. Excuse the lack of organization/forethought.
Support is walking me through removing all connections, uninstalling, reinstalling, etc. They also had me age verify, which my account already was. Im unsure how this will progress. This is just to warn others that this is a risk, if you care more about gmail/drive than antigravity maybe avoid altogether unfortunately.
I will report back what happens. Sorry I posted this in the wrong location twice, wanted to find the newest thread so people are made aware.
If you see this error you may want to contact support to see if your account was incorrectly flagged.

It would be great if there was a repost feature to repost this or @ someone directly from the Antigravity team to address issues like this more quickly and with added visibility.

I tried and it works with claude
Carl,
I encountered this same thing today. See my comment above.
DO NOT submit the appeal, unless you are 100% confident. I will not be, as whatever is flagging accounts due to this is likely to be seen as real from the support people who read the appeals- resulting in account deletion. I would not like my entire google account deleted, so I am opting out of Antigravity and will have to just eat the ultra plan cost for the rest of the month.
Let me know what updates you have. I went through the process and they elevated it to higher levels of support and told me to await an email. I was told to stop using antigravity to avoid any risk of account issues.
I suspect this is a bug/issue with how Antigravity coordinates with Google Support. I am 100% sure I was using the Antigravity Marketplace, and the correct antigravity, and was doing nothing against ToS; as you have experienced.
I hope this is resolved ASAP, but I am now permanently wary of how dependent I am on Google. Gmail, Drive, Youtube, Security Cams, the list goes on. The fact that they can let an issue like this through and their only protocol for appeals is to delete the account (why would anyone submit an appeal for a known false flag knowing this) makes me consider that I need to start moving to alternatives slowly. Which is disappointing; google was actually the one massive company I thought was quite diligent, has good research provenance, and good software.
Antigravity has been a rough stain on the google reputation.
Please update me if you learn anything else, you may want to contact support to see if your account was also flagged.
I have been using this for 3 months exactly the same as I did today; so maybe the flag does not actually result in anything, but I am told it is what is preventing me from using it today: i instead know that its due to an outage, but whether that means it will have an affect on my google account or antigravity access later has yet to be known. If you also have this account flag but are able to use it after the outage, that would be helpful info.
Thank you Carl. Good luck.
Hey, till today was working ok, i´ve updated to last version and pum!

Hi,
It seems you’re experiencing exactly what I went through. I’m also deep in the ecosystem but decided to rethink my entire workflow. I’ve submitted two tickets and haven’t received a solution or answer for days. No matter what I reply to those ticket emails, I just get some kind of pre-scripted apology, thanking me for being patient and that my issue was going up to the highest level of importance….-sigh-
So, I cancelled Ultra, stopped using Antigravity, and switched back to VS Code + Copilot, though I’ll probably go back to Cursor. I’m nobody to them, I stopped wasting my time since it’s pretty obvious they don’t care about resolving that issue and the downside of dealing with these Big Tech Fortune 100 juggernauts.
Good luck to you

I’m having the same issue. Do we know when this will be resolved?
esto tiene tintes siniestros, esta afectando solo a cuentas ultra, cuando mando prompt lo mando con gemini 3 flash y en ese momento lo cambio a calude 4.6 o gemini 3.1
Same issue. Google customer service is clueless, keeps telling me restart AG and/or restart computer.

paid for Goole and using Claude model + bad experience 
Even if I am subscribed to Ultra, I am still experiencing it.

This is unacceptable. The level of incompetence here is astounding. Antigravity is almost unusable. it takes about 50 “Continue” messages to get one prompt through. It is astounding how broken this service has become. I’m at a loss for words, especially with how many devs out there like myself who are just getting completely shafted, where heavy workflows have been built up around Antigravity as a foundation for productivity and certain expectations manifested given the way things were working. Many of us made plans which effect our livelihoods here, and now Google has fallen through on those promises and not even a peep can be heard in response for such ill service. Shameful.

Pagando Google AI Ultra y obtienes este error constantemente, no entiendo que estoy pagando entonces
Logo agora que eu estava a gostar de desenvolver com o Gemini Pro. Infelizmente o serviço parece que está instável.
The issue is still not fixed…
