Antigravity + Gemini 3 are serious contenders

 

The News

Google’s rebirth as the AI behemoth it was always meant to be has finally come to fruition. With the release of Gemini 3, Google has made it clear that it can compete with—and even surpass—OpenAI and Anthropic. And now it seems everyone and their mother is shipping AI-enhanced IDEs which, in almost all cases, are forks of VS Code. Google’s offering is no exception: Antigravity—a rather interesting choice of name.

The Need

I’ve been working on a Node.js–based orchestration framework for AI agents—yes, yet another one, even though there are already countless options out there. I looked, but none really did what I wanted, so I went ahead and built my own, thanks in part to the helping hands of Claude Code (Anthropic). Bottom line: it works fine. There’s still a lot of manual tweaking required, but I was able to achieve things I couldn’t do with plain ChatGPT or Claude alone. However, it lacks a UI. I didn’t even consider building or using one, because I figured I just needed something simple. But I’ve now realized that once you have a workflow that works and want to expand, the lack of a UI is exactly what holds you back.

The Solution: Enter Antigravity + Gemini 3

I could have simply asked Claude to help me build a UI, but this felt like the perfect opportunity to try something new for something new. So I prompted my way through explaining what I wanted the UI to do, and to my amazement (a word I’ve used far too often this year given the rapid pace of progress), three prompts later I had a simple UI in which I could construct workflows by dragging in tasks and connecting them—similar to what you’d do in more advanced workflow tools. The incredible part—beyond the fact that it took only three prompts—is that it understood the existing workflow perfectly and generated a UI that didn’t modify any of the existing code. It literally just built a UI on top of it.

So What’s the Conclusion?

We’re nowhere near done advancing LLMs. Gemini 3 is so good that it’s scary all over again. I used to joke that Claude Code could easily replace ten developers; with Gemini 3, I’m starting to wonder if I was being too modest.
