I personally don't like antigravity very much, because in some hallucinations the AI ends up removing important parts of your code. It doesn't have a continuous learning engine for your project; if you switch users you may experience problems due to loss of context when reloading the session.

I wish this could work with your monthly subscription where you get a flat quota in Antigravity with a free account / $20. edit: Is this not built out of VSCode? Isn't Antigravity based on VSCode? VSCodium has a Web build https://github.com/VSCodium/vscodium UI wise it might be good to make it clearer you don't need to put in an API key to try it.

I completely agree! Its so frustrating that providers (google, openai, anthropic) silo their $20/month consumer subscriptions away from their API access. It would be amazing if paying that flat fee gave you a 'personal API key' to use in open source UIs like this. Unfortunately, we're stuck with standard API keys for now. Though I believe that google aistudio has decent free limits on gemini 3 flash with the free api…

This isn’t some temporary problem. Flat rate subscriptions include a hidden term that you dont pay out of pocket. Its the LTV of their speculation on the product surface and the belief they will retain you due to laziness and muscle memory

But... does it clone Antigravity's commitment to storing keys at well known locations on disk in plain text?

Even if it did, its OSS now, open a PR! :P Note: It's not actually the same app, just a clone/reproduction so it's built from scratch essentially.

Nice project. For the agent loop, the two UX pieces I'd make impossible to miss are: 1) a plan/checkpoint before file writes, and 2) a diff/revert view after each tool run.

WebContainer is great for "run it and see", but state can get fuzzy fast. The more the UI shows exactly what changed and why, the safer it feels to trust the agent.

Is there any other editor that comes close to JetBrain's Git integration? All I see is forks of forks of VSCode, and I'm wondering what the incremental gain of yet another does-the-basic-text-editing editors we need. This is in no way directed at OP, but it seems like a lot of wheels spinning around the world and surprisingly little progress at the Pareto limit.

Funnily enough, I actually prefer the VSCode model for git. On the occasions I use IntelliJ, I find the git actions spread across multiple panels or dropdowns. In VSCode, it's all in one place and the current state clearly visible. YMMV ofc.
