SOLVED - Antigravity hangs due to language_server_windows_x64 high memory consumption

Google Antigravity

I can maybe push a couple of prompts before the app hangs. I have noticed in these cases the language server consumes most of the available RAM. Any help appreciated.

EDIT
Ok I think the project just got too big and I was working in the root folder. I am now working in a sub folder and have no issue at the moment

This actually only served as a temporary fix, even the app in the subfolder got too big. I eventually identified the main cause to be the application source code files being too big. Some were over 1000 lines long. I instructed the agent to modularise the code as much as possible to prevent the language server having to index massive files and this appears to be a more permanent fix to my RAM issues.

Same problem and it started when I updated antigravity. Device is super hot and feels like it will melt if I work another 30 mins !!

it seems to be a memory leak + big issue of optimisation in working Agent (it’s my own case => CPU is over with Agent, draining my battery and launching refreshing ventilators everytime i use Antigravity Agent (even if a simple request like)

this issue is not solved, i agree with you

Hi,
I’m experiencing the same problem. My project isn’t that big, but the issue seems to have started after installing Docker/Phi-3 and Ollama. The following error keeps recurring in the Output Terminal window: Chrome Dev Tools constantly tries to establish an MCP server connection. I still haven’t been able to solve the problem. Any ideas?

(The following sentence is a separate, unrelated thought and not part of the problem description.) Output In Terminal “2026-02-11 10:54:16.623 [error] [Window] [Extension Host] [ExtensionServer] Failed to get Chrome DevTools MCP URL: Error: command ‘antigravity.getChromeDevtoolsMcpUrl’ not found

I am having same problem. This exe is grabbing 1.5+ GB of Memory.

I wrote a hotfix extension to patch the error, but the IDE still crashes after a while :frowning: same issue
