Wow, I can't believe this hit the front page! Its past midnight here in the UK and I have to be up early for GCSEs, so I'm heading to sleep. I'll read and reply to all your comments and questions first thing in the morning! Thank you all so much for the amazing feedback and stars so far.

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.

Edit: A mod suggested I add in how I actually use this! Right now, its honestly just a massive side project that serves as a fun distraction from my GCSE revision. But I mainly use it to test out quick HTML/CSS/JS ideas in my browser when I get an idea, without needing to boot up a full dev environment or worry about rate limits.

I wish this could work with your monthly subscription where you get a flat quota in Antigravity with a free account / $20.
UI wise it might be good to make it clearer you don't need to put in an API key to try it.

Cool, seems a bit niche? Antigravity is ok but not so ok as to want to clone it, might just be me.

GCSEs, I was disallowed from taking my IT GCSE because I "hacked the school".

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.

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

Should've named it ZeroGravity to stay true to its design goals.

If you are just a high schooler working on this, that's freaking amazing!

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.
