As an internal tester for Google Antigravity, I’ve had a front-row seat to the single biggest step-change in software development since the original IDE. But this isn’t just about faster coding. It’s about scaling yourself.
I’ve been biting my tongue for weeks.
For solo founders and non-technical creators, the dream has always been to build a “unicorn” product without needing a unicorn team. We are finally there.
We are witnessing a fundamental shift: from coding to orchestrating.
Antigravity isn’t just an editor; it’s an Operating System for Artificial Intelligence. But more importantly, it gives you something money can’t easily buy: an instant, world-class founding team.
Meet Your New AI Co-Founder Team
When you open Antigravity, you aren’t just opening an IDE. You are walking into a room with three high-powered executives ready to work for you 24/7:
- The CTO (Gemini 3 Pro): Your AI coding agent co-founder. It knows every framework, refactors legacy code in seconds, and architects scalable systems while you sleep.
- The Design Director (Nano Banana Pro): Your creative visionary. It generates premium UI assets, icons, and entire design systems on the fly, ensuring your product looks like a million bucks from Day 1.
- The Testing Director (Browser Use): Your QA lead. It doesn’t just run unit tests; it launches a real browser, clicks buttons, fills forms, and verifies user flows exactly like a human would.
This is a powerful team for anyone who wants to build a one-person billion-dollar company! This team is more complete—and faster—than most of the founding teams applying to YC today.
With this team, you unlock a new era of development Vibe Coding.
What is Vibe Coding?
Vibe Coding (n.): The state of flow where you focus purely on architecture and creativity, while your autonomous executive team handles the implementation, design, and testing in parallel.
If you’re a solo founder, prepare to become a full-stack organization overnight.
1. The CTO at Work: Your New Mission Control 🧑🚀
We’ve all been there: you have a brilliant idea, but you’re stuck on a React hook, or you’re waiting for a freelancer to fix a CSS bug. It’s synchronous, slow, and kills your momentum.
Antigravity solves this by giving you a CTO that works in parallel with you. The workspace is separated into two distinct, powerful surfaces:
- The Editor: Your familiar canvas for synchronous work—fixing typos, tweaking UI, committing small changes.
- The Agent Manager: Your Mission Control where your CTO operates.
This is the “Aha” Moment for founders. You can spawn a high-priority agent to “Research and implement OAuth for the API” in the Manager. While your CTO is planning, fetching dependencies, and writing the code in the background, you can be in the Editor polishing the landing page text.
This parallel agent mode is what truly separates Antigravity from everything else. You are no longer just a coder; you are a Technical Director managing a brilliant CTO.
💡 Cross-Reference: Unlike CLI-based agents like Gemini CLI or Claude Code, the Manager surface gives you a visual dashboard of your CTO’s internal thought process, or Artifacts (Task List, Implementation Plan, Walkthrough). You don’t just see the code; you see the intelligence planning the code.
2. The Testing Director: Trust, Don’t Just Verify 🧪
For solo founders, the biggest barrier isn’t writing code—it’s testing and validation. How do you know the code works without spending hours setting up a test suite or clicking through the UI?
Enter your Testing Director.
Antigravity’s native browser integration is the killer feature. Your Testing Director isn’t just generating files; it has its own embedded Chrome instance. It doesn’t just say it fixed a bug; you watch its cursor navigate the page, click the buttons, and verify the outcome against the original request.
The AI becomes your integrated QA department. This means less friction, less fear of deploying, and a faster path from idea to revenue.
3. The Design Director: Nano Banana Pro ✨
For too long, the design layer and the coding layer have been separate worlds. We build the architecture, then we stop, switch to a design tool, hire a designer, or settle for “Lorem Ipsum” images.
Antigravity natively integrates Nano Banana Pro—your new Design Director—directly into the development workflow. This is a game-changer that we must treat with serious reverence.
Need a hero image that perfectly matches your app’s new color scheme? Need a set of 50 icons? Ask the agent, and your Design Director delivers high-fidelity assets instantly, right into your project folder. You can even generate entire UI mockups and diagrams, then ask the CTO (the coding agent) to turn them into React components.
This means your Vibe Coding process is now truly end-to-end—you can design and build without breaking flow.
4. The Monster Within: Gemini 3 Pro and Openness 🤯
At its core, Antigravity is a platform, and its power is rooted in the “monster” models it orchestrates.
Gemini 3 Pro—the brain behind your CTO—sets a new standard for code understanding, complex dependency management, and multi-step planning. You can even choose the specific “brain” for the task, toggling between Gemini 3 Pro (High) for complex reasoning or lighter models for speed.
But what I love most is the platform’s commitment to openness. Antigravity doesn’t lock you in. You can also run powerful autonomous agents powered by:
- Claude Sonnet 4.5
- GPT-OSS (Open Source Specialist)
This model optionality ensures Antigravity remains the most powerful and flexible coding environment for years to come.
5. Critical Take: The UI Needs to Catch Up ⚠️
I love this tool, but I have to be honest: the UI naming conventions are confusing and, frankly, need a rethink.
Antigravity presents you with two main modes: Planning and Fast. To a human, “Planning” implies a passive state—drafting a roadmap, discussing architecture, or thinking without acting. In other agents like Claude Code, “Plan” mode is exactly that: a safe space for discussion.
In Antigravity, “Planning” is a misnomer. It should be called “Architect & Execute”.
When you are in Planning mode, the agent isn’t just taking notes. It is actively researching, checking files, and—here is the critical bug—sometimes it just starts executing code without waiting for your final “go.” I’ve had moments where I thought we were just brainstorming a implementation design, and suddenly the agent is running migration scripts. That is a “rogue agent” behavior that needs better harnessing.
Similarly, “Fast” mode is a poor name. It sounds like a performance setting, but it really means “Direct Execution” or “Doer Mode”.
My advice: Ignore the labels.
- Treat Planning as “The Architect” (use for complex, multi-file tasks).
- Treat Fast as “The Builder” (use for quick fixes and simple commands).
The intelligence is there, but the controls are still in beta. You need to learn the quirks to master the machine.
