Google Antigravity and Claude Code are both AI coding agents, but they come from opposite ecosystems. Antigravity is Google's take, wired to its models. Claude Code is Anthropic's terminal agent. If you're choosing between them in 2026, the real question is which ecosystem, and how locked in you want to be.
The core difference
Antigravity is built around Google's AI stack and integrates with its ecosystem. Claude Code is a terminal-first agent that runs Anthropic models natively and can reach others through a router. One is ecosystem-centric; the other is terminal-centric and more model-flexible when you add a router.
Antigravity vs Claude Code at a glance
| Google Antigravity | Claude Code | |
|---|---|---|
| Maker | Anthropic | |
| Default models | Google's models | Anthropic (Claude) native |
| Form factor | Google ecosystem agent | Terminal-first agent |
| Multi-model | Tied to Google by default | Others via router |
Which should you use?
Pick based on your stack
| Pick | When |
|---|---|
| Choose Antigravity if | You're deep in Google's ecosystem and want an agent that fits it. |
| Choose Claude Code if | You want a terminal-first agent with strong Anthropic models and the option to add others. |
| Avoid lock-in if | You don't want to be tied to one provider's models or billing, add a router. |
The thing both tools share is lock-in: by default you're on one company's models and one bill. If a model gets limited, pricey, or just isn't the best for a task, you're stuck. That's the gap a router fills.
What that looks like with Wuwei
| Benefit | Detail |
|---|---|
| No ecosystem lock-in | Run Claude Code against Google's, Anthropic's, OpenAI's and other models from one entry point. |
| Pay-as-you-go | One account, billed for what you use, not a single-provider plan. |
| No proxy setup | Natively supports OpenAI-compatible endpoints, so there's nothing to configure. |
| Remote + mobile | Run tasks on remote devices and check in from your phone. |
FAQ
What is Google Antigravity?
Antigravity is Google's AI coding agent, built around its model stack and ecosystem. It's positioned as a competitor to tools like Claude Code.
Antigravity vs Claude Code, which is better?
It depends on your stack. Antigravity fits Google's ecosystem; Claude Code is terminal-first with strong Anthropic models and can reach others via a router. Neither is universally 'better.'
Can I use other models with Claude Code?
Yes. Claude Code runs Anthropic models natively, and with a router like Wuwei you can point it at many other providers.
How do I avoid being locked into one provider?
Use a router that sits in front of your agent. Wuwei lets Claude Code reach many models with pay-as-you-go billing, so you're not tied to one ecosystem.
