Google Antigravity vs Cursor (2026): Free Preview vs Proven Meter

TL;DR: The Verdict Up Front

Every launch-week comparison of these two tools argued about features. Eight months in, features aren't the story — the meter is. Both are agentic coding environments that will build real software from prompts. The difference you'll actually live with:

• Cursor: $20/month Pro, $60 Pro+, $200 Ultra. Effort-based usage that can outrun the sticker, but a pricing model you can observe, forecast, and budget.
• Antigravity: $0 in public preview as of August 2026 — with metered quotas Google has tightened several times since the November 2025 launch, and no published standalone price for what comes after. Paid headroom rides Google's AI subscriptions: AI Pro $20/month, AI Ultra $249.99/month, top-up credits at $0.01 each.

Main workflow: Cursor. Free experiment: Antigravity. Both: review the output like it came from a fast intern. The reasoning, and the cases where I'd flip that verdict, below.

Price Head-to-Head: $0 Is a Number, Not a Forecast

Today's math is unfair to Cursor and everyone knows it: free beats $20. The comparison worth making is the one you'll face when Antigravity's preview ends — and the quota-tightening pattern says treat that as "when," not "if." At the paid tiers the two converge almost exactly: AI Pro $20 vs Cursor Pro $20; AI Ultra $249.99 vs Cursor Ultra $200. At that point the decision variable becomes quota depth per dollar — how much real agentic work each subscription actually clears before throttling — and as of August 2026, nobody outside Google can quote Antigravity's side of that number. Cursor's effort-based usage math has its own traps (the sticker says $20, the meter disagrees), but at least the meter is public and observable.

Maturity: One of These Is a Preview

Cursor has years of production use, a stable pricing history, and failure modes the community has documented to death. Antigravity is a genuinely impressive preview — Gemini-powered, agent-first, free — that is still changing under its users: quotas have tightened repeatedly, and the terms that matter (what happens to your workflow when the subsidy ends) are unpublished. That's not a knock on the engineering; it's the definition of preview software. The rule I give clients: never let a preview-priced tool become a load-bearing dependency without a fallback you've tested. If your codebase pays your rent, the boring known quantity wins by default.

Who Should Pick Which

Pick Cursor if: you ship client or revenue work daily, you need forecastable costs, or your team standardizes on one tool. The worth-it math is straightforward for working developers at $20.
Pick Antigravity if: you're experimenting, building side projects, or price-sensitive enough that free frontier-model capacity outweighs quota roulette. It's the best $0 in the category right now.
Run both if: you want the honest answer — a normal week of real work in each, counting rate limits, queue waits, and rework. That two-week test beats every comparison post on the internet, including this one.
Neither, yet, if: you're a non-developer hoping the tool choice is what stands between you and a production app. It isn't — the gap is review and architecture, and that gap invoices the same regardless of logo.

The Part Both Sides of This Comparison Get Wrong

I bill for rescuing AI-built apps, and here's the pattern: none of my rescue invoices trace to which tool wrote the code. They trace to what didn't happen afterward — no security review, no error handling, no architecture pass before real customers showed up. Antigravity's agents and Cursor's agents will both happily generate an app that demos beautifully and falls over in production. Whichever you pick, the professional move is the same: review everything like it was written by a fast intern, because functionally it was. If you've already got an AI-built app in front of customers, run the 20-point security checklist against it this week — it's free and it finds the expensive problems while they're still cheap.

What to Do Next

Today's micro-action: if you're currently paying for Cursor and curious, install Antigravity tonight and give it one real ticket from your backlog — not a toy prompt, a real one. Log where it shines and where it hits the meter. You'll know more in an hour than any comparison post can tell you. And whichever tool builds your next feature, the full Antigravity pricing breakdown covers the quota math in detail before you commit a workflow to it.
