Antigrafity IDE can't log in, even though the browser says it's successfully logged in

Does anyone here know how to fix the problem of Antigrafity IDE not being able to log in? I’ve installed it more than 5 times and still can’t log in. Please help me if you know.

Even though the browser says the login was successful, when I open the antigraffiti it’s still on the login page. Please tell me if anyone knows.

Hi @Febri_yogantara,

Welcome to the Forum,

Thank you for reaching out regarding the issue where the browser indicates a successful login, but Antigravity IDE fails to complete authentication and remains on the login screen.

This typically occurs when local authentication session state becomes desynchronized or when local browser, firewall, or network configurations intercept the OAuth loopback redirect back to the IDE.

Please try the following troubleshooting steps to resolve this:

  1. Reset Onboarding & Clear Session State:

    • Launch Antigravity IDE.
    • Open the Command Palette by pressing Ctrl+Shift+P (Windows/Linux) or Cmd+Shift+P (macOS).
    • Search for and select: Antigravity: Reset Onboarding. This clears cached OAuth tokens and reloads the window.
    • Alternative (Manual cleanup): If you cannot access the Command Palette, close Antigravity and manually delete the local configuration directory:
      • Windows: %APPDATA%\Antigravity
      • macOS / Linux: ~/.config/Antigravity
  2. Check Browser & Loopback Redirects:

    • Ensure your browser allows local redirects to localhost / 127.0.0.1.
    • Temporarily disable strict privacy extensions, ad/pop-up blockers, or VPN/proxy tools that might block local loopback callbacks.
    • Try temporarily setting another browser (e.g., Google Chrome) as your default browser to complete the OAuth redirect.
  3. Verify Account Eligibility & Re-authenticate:

    • Click Sign In inside Antigravity IDE.
    • Sign in using an eligible personal Google Account (@gmail.com) or supported Workspace account.
    • Make sure your account has completed age verification at https://myaccount.google.com/age-verification if prompted.
  4. Ensure the IDE is Updated:
