Is Antigravity with Gemini 3 Pro Really Better Than Claude Code?
A real-world developer test comparing Antigravity (Gemini 3 Pro) with Claude Code for actual software development.
The AI coding tool landscape changes fast. When Google released Gemini 3 Pro and Antigravity started making waves, I had to test it head-to-head against Claude Code. Not with toy examples — with real development work.
The Test
I took the same set of tasks and ran them through both tools: - Building a new feature in an existing codebase - Debugging a complex issue - Refactoring a module - Writing tests - Creating a new project from a description
The Results
Neither tool was universally better. They have different strengths:
Where Claude Code Won - Understanding project context and architecture - Generating code that fits the existing style - Careful, thoughtful refactoring - Fewer bugs in the first pass
Where Gemini/Antigravity Won - Speed of generation - More aggressive with large changes - Better at certain boilerplate tasks - Sometimes surprising creativity with solutions
My Take
The tool that works best depends on what you're doing. For production code in an existing project, Claude Code's careful approach wins. For rapid prototyping and throwaway tools, Gemini's speed is valuable.
The real insight isn't which one is "better" — it's that having multiple tools makes you more productive than being loyal to one. Use the right tool for the task. And expect this comparison to be outdated in three months when both tools release updates.
