I banged out a simple FastAPI endpoint/tool (along with dockerization and deployment) and a media-heavy Astro website (along with Cloudflare Pages publishing) in Google's Antigravity2.

Not really a recommendation since I don't have a good benchmark of these tools but Antigravity's /grill-me feature where it asks you a bunch of questions like a system/business analyst and gives you an implementation plan for review (and can actually change it further) is pretty cool and it is certainly fit for what you intend.

Heard also good things about Zed and am testing it right now. So far I managed to... edit a json.
