Like many Google Antigravity users, I was very excited about the Antigravity 2.0 announcement at Google I/O 2026.
Who would't be enthusiastic about the new cost efficient Gemini 3.5 Flash? Plus, a standalone desktop app form factor that seems to rival Claude Code and OpenAI Codex at that!
There are a lot of great things to be eager to try it out but I want to provide some pointers in the upgrade and migration to save you some headaches and hassles later.
The upgrade path from Antigravity 1.0 to 2.0 is straightforward:
At the Antigravity 1.0 user interface, there should be a button that asks you to restart the app to update.
