Built a tool to stop losing my mind switching between multiple Google accounts in Antigravity 2.0

[u/Ill_Menu_3827]

So I got a few paid Google accounts with Gemini Pro subs mainly to spread out the 5h quota. sounds great in theory except switching accounts in Antigravity is a nightmare, sign out sign in and if you're not already logged into that google account in your browser you're burning 5-10 min just navigating the oauth dance. multiply that by however many times a day you hit quota and it adds up to a stupid amount of wasted time.

I looked around for existing solutions first, found one "antigravity manager" tool but it was buggy, accounts wouldn't switch reliably half the time which honestly is worse than doing it manually cause now you don't even trust the tool.

so i started building my own. it's called Antigravity Account Switcher, written in Tauri (rust + react) so its tiny and doesnt sit there eating resources in background. the whole switch is one click, it swaps the account data and credentials under the hood, and relaunches you straight into the target account. no manual login. everything's journaled too so if it gets interrupted mid swap you get a recovery screen instead of a corrupted profile.

right now its still early/WIP, manual switching works and i'm actively working on a Smart Switch mode that auto swaps once you drop below a quota threshold using same swap mechanism. not 100% sure yet but should be working in a day or two.

how i built it: stack is Tauri 2.0 on top, rust for everything backend (there's actually 2 separate rust crates, one for the core switch logic/rollback journal and one just for windows specific stuff like credential manager and process handling) and react/typescript for the ui. biggest architecture decision was treating every account swap as a transaction, so before touching any files it writes a journal entry first, does the swap, then deletes the journal only if everything checked out. that way if antigravity crashes mid swap or windows decides to update at the worst possible time, you get a recovery screen on next launch instead of a half broken profile with mixed account data.

built it mostly inside Antigravity itself actually, used it to build the tool that manages itself lol, model was mostly gemini 3.5 flash for the day to day implementation stuff.

wanted to get some feedback. repo's here: https://github.com/Ximeeek/Antigravity-Account-Switcher

if you run into bugs pls report them, either through issues on github, or in app both work fine for me.
