Antigravity pricing: free, $19.99 on AI Pro, Ultra from $99.99

How much does Antigravity cost on each plan?

Antigravity has no price of its own. Google sells it inside its Google AI plans, so the price you pay buys a bigger quota. We read each row from Google's Antigravity pricing page, its plans page, its models page and its US subscriptions page on 8 November 2026. US prices, before tax:

Every plan gets "Unlimited Tab completions" and "Unlimited Command requests." The quota only counts agent work. Google says its limits "correlate with the amount of work done by the agent," so a long task spends more of it than a short one. You can't add your own API key to stretch it: the plans page lists "Bring-your-own-key (BYOK)" as not supported.

Google AI Plus isn't worth buying for Antigravity. The models page puts it in one column with Free, and the subscriptions page lists no Antigravity line for it at all. Pro is the first plan that changes anything.

What does an Antigravity task cost at API rates?

An Antigravity task costs $2.51 on Gemini 3.8 Flash and $11.73 on Gemini 4 Argon at pay-per-token API rates, by Artificial Analysis's count. Its Coding Agent Index v2.0 runs each agent on the same coding tasks and prices the tokens it uses. The site says the figure is "intended to show pay-per-token API cost, not consumer plan pricing." We read these rows on 8 November 2026:

Argon is the expensive way to run it. It costs 31 cents more per task than Claude Code on Opus 5.5 and scores nine points lower. Gemini 4 Carbon does better on both counts, but you can't buy it yet. Google's Carbon post of 28 October gives it only to "a subset of cyber defenders" for now.

These costs will move. Google's Gemini API price list doubles Argon's rates on 1 December, and 3.8 Flash's on 1 January 2027. Priced at those new rates, the same tasks would cost about $23.46 on Argon and $5.02 on Flash. Every rate is in our Gemini API pricing table. On a plan you don't pay per token. A rise would reach you through credits, which Google bills at its Enterprise rates, or through the API.

How much do Antigravity AI credits cost?

Antigravity AI credits cost $25 for 2,500, as The Register reported on 12 March 2026. Google doesn't print a credit price on any Antigravity page we read. Its plans page says only that credits are "consumed at standard Gemini Enterprise consumption pricing," and that Pro and Ultra users can spend them "above the baseline quota." The pricing page lists the credit pool on Pro and Ultra only, not on the free plan.

You choose how they're spent. A setting called AI Credit Overages gives you two choices: "Never use AI credits automatically," or "Always use AI credits when the baseline quota is exhausted." Leave it on the first if you want a hard ceiling on your bill.

Credits get poor value past a point. Ultra 5x costs $80 more than Pro. At $25 per 2,500, $80 buys 8,000 credits. So if you'd buy more than that in a month, Ultra 5x is the cheaper way to get the extra room. Back in March, The Register quoted a Reddit user who said they now hit weekly limits at "less than 9 million input / 200 thousand output tokens."

What does a typical month of Antigravity cost?

A typical month of Antigravity costs $19.99 if Pro's five-hour windows cover your work, and $44.99 if you also buy one credit pack. It's the subscription plus whatever credits you choose to buy, since there's no metered bill on a plan. Here's how five kinds of developer would pay, with the $25 pack from The Register's report:

The math is plain addition: $19.99 plus $25 is $44.99, and $19.99 plus $75 is $94.99. That last row is only $5 short of what you'd pay for Ultra 5x, and Ultra also gets the five-hour windows. So once you're buying three packs a month, it's time to move up a plan.

What does a pack buy? Google hasn't said. If 2,500 credits pay for $25 of usage at list price, they'd cover about 10 tasks of Artificial Analysis's size on Gemini 3.8 Flash, or about 2 on Argon. Treat that as a rough guide. Your tasks are probably smaller than a benchmark's.

Is Antigravity free?

Yes. Antigravity's Individuals plan costs $0 and needs no subscription, with "Basic weekly rate limits" on agent work. Tab completions and Command requests are unlimited on it, as they are on every plan. Its quota refreshes once a week, not every five hours.

The free plan gets thinner on 18 November. Today it can also use Claude Sonnet 4.6, Claude Opus 4.6 and GPT-OSS-120b, but Google marks all three "Will be removed on November 18, 2026." After that, Gemini 3.8 Flash is the only agent model it has. Gemini 4 Argon isn't on Free. Google says Argon is "Available with paid Google AI Pro plans or on trial with eligible premium devices," and the Claude 5.5 models on Pro are for "non-trial subscriptions only."

Is Antigravity cheaper than Cursor or Claude Code?

Antigravity and Cursor both start free, Claude Code starts at $17 to $20, and at about $20 a month Antigravity ties Claude Code. We read Cursor's and Anthropic's pricing pages on 8 November 2026:

Cursor's pricing page lists Plus at $8 with "Grok models only," and Premium at $30 with "Third-party models at API list price," billed separately by usage. If you want Claude or GPT inside Cursor, you're on Premium or above and paying for those tokens on top. For the agents themselves, best AI for coding ranks them on the same Artificial Analysis index.

What does Antigravity cost next to the rest of your AI stack?

Antigravity costs $19.99 a month on the plan most people use, and it often sits next to two more chat subscriptions. A developer on Google AI Pro who also keeps ChatGPT Plus and Claude Pro pays $59.99 a month. Swap Cursor Premium in for the editor and it's $70. Here are the lines, read on 8 November 2026:

Whizi, which publishes this page, can't replace Antigravity. It has no coding agent, no IDE and no API, so keep Antigravity, Cursor or Claude Code for the editor work. Whizi Pro costs $29.99 a month and puts Claude, GPT and Gemini in one chat, with credits per message that vary by model. If you pay for ChatGPT Plus and Claude Pro only to chat, one Whizi plan can cover that side. If you use Codex or Claude Code, keep the plan that includes it.

Will Antigravity pricing change?

The plan prices aren't scheduled to change, but what they buy is. On 18 November, three models leave the free plan and Pro. On 1 December, Google's Gemini API price for Argon doubles, which matters if you run Antigravity through the API on Google Cloud. Google's API page notes that Agent Platform prices "may differ," so check your own rate card.

Google has changed the deal before. Antigravity launched in preview in November 2025 with no announced price, and in March 2026 users protested when AI credits arrived and quotas got tighter, per The Register. Google's plans page still says "Usage limits for this service are subject to modification." For now, the API route has one perk: Google doesn't bill environment compute for the Antigravity Agent "during the preview period."
