Is it safe to delete ~/.antigravity-ide?

Review first. Likely recoverable, but it costs you something to get back. Read before you move it.

What it is
  • Google's Antigravity documentation does not describe this folder.
  • It names a different one, ~/.gemini/antigravity-ide, as the IDE's app data folder.
  • On the Mac this rule was checked on, this folder held an extensions folder (158 MB, about 3,400 files), a launch-settings file (argv JSON) and a small folder of its own.

If you remove it

Spaceific cannot say exactly what removing it does: its vendor does not describe this folder. Its extensions and launch settings go with it, and whether Antigravity IDE installs them again is not documented.

How it comes back

Put Back from Cleanup History while it is in the Trash. Spaceific does not know whether Antigravity IDE recreates what is in it.

The proof

Verified by
  • vendor documentation: Google Antigravity, “Hooks” (https://antigravity.google/docs/hooks/), read 9 Nov 2026, “For Antigravity IDE, <app_data_dir> in hook payloads resolves to ~/.gemini/antigravity-ide.” No Antigravity page found describes ~/.antigravity-ide.
  • What it holds was read by name, size and type only on 6 Nov 2026 (Step R-0); no file in it was opened.
Checked on
macOS 26.6.2, Antigravity IDE 2.5.5
