Antigravity Pricing (2026): The $20 Plan Is the Default

Antigravity starts at $0, with consumer Google AI plans at $4.99, $19.99, $99.99, or $199.99 a month; the $19.99 Pro plan is the sensible paid default for regular solo work unless you need Gemini 4 Argon inside Antigravity, which requires Ultra or eligible Gemini Enterprise access. The free plan is useful until its weekly agent quota or model selection blocks you; the two Ultra tiers buy 5x and 20x Pro quota, and only the $199.99 tier improves the cost per quota unit.

The Google prices, models, and plan labels below were verified on October 14, 2026 against Google's live Antigravity pricing page, Google's US AI plans page, and the linked billing documentation. Antigravity's pricing page does not print Pro or Ultra subscription prices and shows one Ultra card; the 5x and 20x labels and dollar amounts come from Google's consumer plans comparison. The wider bundle comparison is in Gemini pricing.

Antigravity pricing at a glance (October 2026)

Google AI Pro at $19.99 a month is the right paid starting point unless Argon is a requirement. For Argon inside Antigravity, an individual needs Ultra, starting at $99.99 a month. Plus is too constrained for dependable agent work, Ultra 5x buys headroom and Argon access without improving quota unit economics, and Ultra 20x is a power-user purchase that only makes sense after measured usage.

What each Antigravity plan buys

The plans sell agent headroom and model access. The basic Antigravity environment stays available across individual tiers; the price changes the rate limits and which models you can select. The pricing cards describe Pro as adding more rate limits and a flexible AI credit pool, and Ultra as adding still higher limits. Credits are an overage mechanism, explained below.

Individual: $0 is a useful floor

Antigravity Individual costs $0/month and is Generally Available, not a timed preview. Google lists access to agent models, unlimited Tab code completions, unlimited Command requests, and basic weekly rate limits. Unlimited completion and Command access do not mean unlimited agent work.

Gemini 3.8 Flash has been available in Antigravity since September 1, 2026. Google's release post confirms the launch. The current model matrix lists Gemini 3.8 Flash across Free/Plus, Pro, Ultra, and Enterprise. Gemini 3.7 Flash, Gemini 3.6 Flash, and Gemini 3.1 Pro are now listed only for Enterprise.

Since October 13, 2026, Google has been rolling out Gemini 4 Argon in the Antigravity desktop app and CLI for Google AI Ultra subscribers and eligible Gemini Enterprise subscriptions. The matrix also lists IDE extensions, but excludes the separate Antigravity IDE. Google AI Pro does not include Argon in Antigravity, even though Pro and Ultra both get it in the Gemini app. For an individual who needs Argon here, Ultra 5x at $99.99/month is the entry point, $80 more than Pro.

The same matrix lists Claude Sonnet 5.5 and Opus 5.5 thinking models for non-trial Pro subscriptions, Ultra, and Enterprise. Free/Plus and Pro retain Sonnet 4.6 and Opus 4.6 thinking models; GPT-OSS-120b is listed for Free/Plus, Pro, and Ultra. Google marks the 4.6 models and GPT-OSS-120b for removal on November 2, 2026. Budget around the models your tier will retain.

The harder wall is time. Google's plans documentation says users without Pro or Ultra receive a quota that refreshes weekly. A light task may consume less of that bucket than a long, multi-file agent job because Google meters the work performed, not a published prompt count.

Google AI Plus: $4.99 is not the professional bargain

Google AI Plus costs $4.99/month, and the current Google AI comparison labels Antigravity agent requests as limited. Google's credit-purchase rules exclude Plus, so there is no credit top-up on that plan when the allowance runs out.

Plus includes 400 GB of Google storage and a wider set of consumer AI benefits. Buy it for that bundle if the bundle already has value to you. Do not buy it because you expect a dependable coding-agent workday; Google does not publish enough Antigravity headroom to support that expectation.

Google AI Pro: $19.99 is the default

Google AI Pro costs $19.99/month, with an annual option whose current total must be checked at checkout, and changes the quota rhythm from a weekly refresh to a refresh every five hours until the weekly limit is reached. It also allows purchased AI credits after the baseline runs out.

That is the practical difference between evaluation and regular work. A solo technical builder can run agents through the day, recover capacity in five-hour windows, and keep overages off until the usage meter proves they are necessary. The plan also bundles 5 TB of storage and $10 in monthly Google Cloud credits, but those Cloud credits are a separate Developer Program benefit, not Antigravity overage credit.

Google AI Ultra 5x: $99.99 buys Argon and capacity

Google AI Ultra 5x costs $99.99/month and provides 5x the Pro quota in Gemini and Antigravity. Google's Ultra benefits page also lists priority access, higher limits, and first access to new models for Antigravity. Its plan docs specify a quota that refreshes every five hours and the highest weekly limits.

The price is almost exactly five times Pro, so the normalized cost stays at about $20 per Pro-equivalent quota unit. This tier buys Argon access for an individual who needs that model, or capacity for someone who already likes the workflow and keeps reaching Pro's ceiling. It is not a volume discount.

The bundle includes 20 TB of storage and $40 in monthly Google Cloud credits. Count those only if you would buy and use them independently; an unused bundle benefit does not lower the software budget.

Google AI Ultra 20x: $199.99 is the only unit-cost win

Google AI Ultra 20x costs $199.99/month and provides 20x the Pro quota. That is ten times Pro's price for twenty times its quota, cutting the normalized allowance cost to about $10 per Pro-equivalent unit.

The bundle rises to 30 TB of storage and $100 in monthly Google Cloud credits. The same rule applies: these can improve the total Google bundle value, but they are not cash back and do not refill Antigravity's baseline.

Business: a seat subscription or pay-as-you-go

Business buyers now have a published starting seat price. Following Google's October 8, 2026 announcement of the Gemini agent for work, Antigravity's current pricing page routes eligible customers to Gemini Enterprise Standard/Plus from $30 per seat per month, or Pay-as-you-go with a $0 seat fee plus consumption charges. Compare the company plans in Gemini Enterprise.

At the advertised starting rate, an illustrative 10-seat team starts at $300/month in seat fees, before any billable usage or overages. The $0-seat route removes that fixed seat fee, not the usage bill. The pricing page also offers consumption-based API access and centralized administrative controls with eligible subscriptions. Google's developer-tools setup guide requires a supported subscription and an invoiced Cloud Billing account for the subscription route.

Set a usage cap before the rollout. Google's subscription overage settings let you set a project monthly spend limit for overages and Pay-as-you-go usage, including Antigravity. In Gemini Enterprise, open Usage & Spending, then Usage, then Project monthly spend limit. Configure the Cloud Billing spend-cap action for Vertex AI (aiplatform.googleapis.com), the service Google uses to bill this usage.

The linked API spend-cap documentation scopes a cap to one project and one eligible service. It pauses new usage when gross estimated costs exceed the monthly budget; requests already in flight can still finish and incur charges. Subscription seat fees are outside that cap. A usage cap is useful budget control, not a promise that the whole invoice cannot exceed its amount.

The business card lists the Antigravity app, the Antigravity CLI, and IDE extensions; the developer-tools setup guide names Antigravity 2.0. Google's CLI announcement describes a terminal interface sharing the agent harness and common settings with Antigravity 2.0. Its extensions announcement names Visual Studio Code, Visual Studio, JetBrains, Zed, and Xcode, with individual access including the free tier; enterprise support for JetBrains and Zed is marked Preview. These are ways to access the product, not separately priced plans on the pricing page.

Who never needs to pay for Antigravity

Stay on the free plan when its available models meet your needs and the weekly agent bucket never blocks a useful outcome. That includes developers who mainly use Tab autocomplete and Command requests, people evaluating the agent workflow on side projects, and occasional users who can move a large task to the following week without hurting delivery.

Free is a poor fit when Antigravity becomes a daily production dependency. A weekly quota can turn a busy Tuesday into several days of waiting, and Google explicitly reserves the right to modify limits as capacity changes. The absence of a published prompt count means you cannot schedule a fixed number of tickets, pull requests, or refactors against it.

The free-plan decision is therefore behavioral, not aspirational. If its models cover your work and you finish a representative week without a quota interruption, paying adds no business outcome. If a cap delays a release, a client fix, or an internal deadline, the $19.99 Pro line has a reason to exist. Scientists can also apply for Google's offer of six months at Antigravity's highest usage tier for 10,000 scientists, with rolling onboarding subject to eligibility, capacity, and selection.

The Antigravity quota math

Ultra 5x costs more without becoming cheaper; Ultra 20x is where the volume discount begins. Using monthly subscription prices and the published 5x and 20x multipliers, the comparison below normalizes the shared Gemini quota to one Pro-equivalent allowance. Google does not publish a fixed number of agent jobs in that allowance; third-party models have separate limits. These are quota comparisons, not an Argon allowance on Pro: Pro cannot select Argon in Antigravity.

• Pro: $19.99 divided by 1x equals $19.99 per Pro-equivalent unit.
• Ultra 5x: $99.99 divided by 5 equals $20.00 per Pro-equivalent unit after rounding.
• Ultra 20x: $199.99 divided by 20 equals $10.00 per Pro-equivalent unit after rounding.

Moving from Ultra 5x to Ultra 20x costs another $100/month and adds 15 Pro-equivalent units. The incremental capacity costs $6.67 per added unit. That is strong value only when the added units get used; unused quota has a cost and no outcome.

You still cannot turn this into cost per merged pull request. Antigravity says consumption changes with task complexity, model choice, and agent work. A simple explanation and a long autonomous refactor do not spend the same amount, and non-Gemini models sit in a separate fixed capacity pool.

Hidden costs in Antigravity pricing

The dangerous number is not the subscription; it is the overage you cannot map to a fixed job count. Google uses a baseline quota first, then lets Pro and Ultra users purchase AI credits when that quota is exhausted.

AI credits are a separate, variable bill

Antigravity offers an AI Credit Overages setting with two choices. Never stops the affected model at its baseline and waits for refresh. Always starts consuming the credit balance, then switches back to baseline after the refresh.

Google's credit-purchase support page gives 2,500, 5,000, and 20,000 credits as example purchase amounts, but does not display their current US checkout prices. Its credit-management page says consumption varies by feature and model. That prevents a reliable public calculation such as dollars per agent task.

Auto-reload can purchase credits up to five times per day, which turns a vague meter into an open budget line. Credits may expire after the period shown when they are acquired. Only a family plan manager can buy more, and Antigravity credit purchases are unavailable in Japan.

The safer default is Never. Turn on Always only after you have set a cash budget and observed how the chosen models consume it.

A flexible credit pool is not an included credit allowance

The Antigravity pricing cards say Pro and Ultra include a “Flexible AI credit pool.” Google's May plan-change notice says AI credits were removed from base Google AI entitlements and now serve solely as overage. Current support pages also describe credits as purchases after baseline exhaustion.

Budget from the documented overage rule: the subscription buys quota, and credits are an additional variable charge. Do not count an included credit balance unless the signed-in account shows one.

Annual Pro billing: confirm the checkout total

Google confirms monthly and annual Pro subscriptions, but its current US plans page no longer displays an annual Pro price. Twelve payments at $19.99/month total $239.88; compare that with the annual amount shown in your account before choosing a billing term. The current public page lists both Ultra options by their monthly prices.

The billing term does not change the buying rule. Google says storage-plan purchases are non-refundable in most countries and regions, with local and app-store exceptions. Prove the workflow monthly before committing the annual amount upfront.

Personal app pricing does not set the organization bill

The $4.99 to $199.99 monthly Google AI ladder prices consumer subscriptions. Business buyers have a separate route: eligible Standard/Plus plans starting at $30/seat/month, or $0-seat Pay-as-you-go plus usage. Budget the applicable seat fees and metered usage separately, with the usage cap configured before deployment.

Cost any Gemini API work outside Antigravity against the separate Cloud agreement. A personal Ultra subscription can raise the app's quota, but it does not make external API calls free or turn variable company usage into a flat monthly line.

Antigravity vs Cursor, Claude Code, and GitHub Copilot on price

At roughly $20, Antigravity competes on workflow and bundle value, not sticker price. Cursor and Claude Pro cost one cent more per month; confirm Google AI Pro's annual checkout total before comparing annual commitments. GitHub Copilot Pro is roughly half the monthly price.

Cursor Pro: the same price for an editor-first workflow

Cursor Pro costs $20/month, just $0.01 more than Antigravity Pro. It includes extended Agent limits, frontier-model access, cloud agents, MCPs, skills, and hooks.

Pick Cursor when the polished editor and direct control are the outcome you value. Pick Antigravity when agent orchestration and the wider Google AI bundle matter more. The price does not decide this pair, which is why the deeper Antigravity vs Cursor comparison should be a workflow decision, not a discount hunt.

Cursor's candid limit is that more agent headroom sits behind higher tiers or usage-based billing. Antigravity's candid limit is less transparent quota accounting. One exposes the money meter more clearly; the other bundles more products around it.

Claude Code: nearly equal monthly, terminal-first

Claude Pro costs $20/month or $200 billed upfront annually, displayed by Anthropic as $17/month, and includes Claude Code. Its annualized cost rounds to $16.67/month. Google still offers annual Pro billing but no longer shows the annual total on its public US plans page, so compare the signed-in checkout price before choosing between annual commitments.

Pick Claude Code when Claude is the model you want and its terminal workflow fits your work. Antigravity also offers a CLI, so terminal access alone no longer separates them; its case is the agent workspace, available model families, and Google bundle. The Claude Code vs Cursor comparison explains the terminal-versus-editor split in more depth.

Claude Pro's limit is shared usage: Claude Code and the rest of Claude draw from the same allowance. Both products can be evaluated monthly before an annual commitment locks cash upfront.

GitHub Copilot Pro: the $10 value option

GitHub Copilot Pro costs $10/user/month, which is $9.99 less than Antigravity Pro. It includes unlimited code completions and next-edit suggestions, $15 in monthly AI credits, model selection, and access to third-party agents including Claude Code and Codex.

Pick Copilot when the job is excellent completion plus agents inside GitHub and familiar editors. Its limitation is posture: it is not the same multi-agent workspace as Antigravity. The lower bill buys a narrower center of gravity, which can be exactly right for a developer centered on GitHub. Antigravity's own IDE extensions mean staying in an existing editor is also possible there.

The decision rule is clean. Choose Copilot at $10 for completion-first value, Claude Pro at $20 or $200/year for terminal-first Claude work, Cursor at $20 for an editor-first daily driver, and Antigravity Pro at $19.99/month for agent-first work plus the Google bundle. An Argon requirement inside Antigravity moves the consumer choice to Ultra, starting at $99.99/month.

What changed in Antigravity pricing in 2026

Google turned a $20-to-$250 cliff into a $20-to-$100-to-$200 ladder on May 19, 2026. Before the change, Google described Pro at $20/month and one Ultra plan at $250/month. It then introduced a $100 Ultra tier with 5x Pro quota and cut the top tier to $200 with 20x Pro quota. The live US page now displays those as $99.99 and $199.99.

The business consequence is a viable middle budget line for someone who has outgrown Pro but does not need the highest allowance. The economic consequence is subtler: the middle tier adds capacity at the same per-unit cost, while the top tier halves the normalized quota cost.

Google also combined Gemini Flash and Pro usage into one shared pool weighted by API pricing. Cheaper Flash work can therefore stretch the Gemini side of the quota further, while non-Gemini models remain on a separate fixed rate limit. Model choice is now part of budget management, even though Google still does not publish enough detail to forecast a job-level bill.

Frequently asked questions

How much does Antigravity cost?

Google Antigravity has a $0 Individual plan. The current US Google AI ladder adds Plus at $4.99/month, Pro at $19.99/month, Ultra 5x at $99.99/month, and Ultra 20x at $199.99/month. Businesses can use eligible Gemini Enterprise Standard/Plus plans from $30/seat/month, or Pay-as-you-go with a $0 seat fee plus consumption charges.

Is Google Antigravity free?

Yes. Individual access costs $0 and includes unlimited Tab completions, unlimited Command requests, and a basic weekly agent quota. It is enough when that weekly bucket does not interrupt valuable work.

Is Antigravity worth paying for?

Google AI Pro is worth $19.99 when the free weekly cap delays work that matters. Plus is not a dependable agent upgrade because requests remain limited and it cannot buy overage credits. Ultra is worth considering when you need Argon inside Antigravity or measured Pro usage reaches its ceiling. Pro access to Argon in the Gemini app does not include it in Antigravity.

Is there anything better than Antigravity?

Cursor is the closest editor-first alternative at $20/month. Claude Code is terminal-first at $20/month or $200/year through Claude Pro. GitHub Copilot Pro is the lower-cost option at $10/user/month for completion and GitHub-centered agent work.

Is Antigravity free for students?

Students can use the $0 Individual plan. The current US AI plans page no longer advertises the previously cited one-year student promotion. Check the offer available to your account before paying, and do not assume a student trial includes every model available to a non-trial Pro subscription.

Does Antigravity have annual pricing?

Yes. Google confirms monthly and annual Google AI Pro subscriptions, but the current public US plans page does not display the annual total. Compare your annual checkout quote with $239.88 for twelve payments at $19.99/month. Ultra prices are displayed monthly.

What is Antigravity's refund policy?

Paid consumer Antigravity access rides a Google One plan; business access uses Google Cloud terms. Google says storage-plan purchases are non-refundable in most countries and regions, with local and app-store exceptions. Confirm the term and current checkout total before committing annually.

Did Antigravity pricing change in 2026?

Yes. On May 19, Google added a $100 Ultra tier with 5x Pro quota and reduced its highest tier from $250 to $200 with 20x Pro quota. Current public prices are displayed as $99.99 and $199.99. The business route now lists eligible Gemini Enterprise Standard/Plus from $30/seat/month and a $0-seat Pay-as-you-go option with consumption charges.

The Monday move

Run one representative week before adding Antigravity to the permanent software budget. Check model access first: if you specifically need Argon inside Antigravity, start with Ultra or eligible Enterprise access. Otherwise, the goal is to measure a blocked outcome, not to guess how impressive an allowance sounds.

1. 1

   Start on Individual

   If you do not need Argon, use the $0 plan for normal work. Keep a short record each time the agent quota blocks a task, including what was waiting and whether Tab or Command could still finish the job.

2. 2

   Upgrade only after a block

   If the available models fit and the weekly bucket never delays delivery, stay free. If the quota delays work, buy one month of Google AI Pro at $19.99 and treat the five-hour refresh as the outcome you are paying for.

3. 3

   Keep overages off

   Set AI Credit Overages to Never during the first Pro month. A hard stop gives you clean evidence about the baseline; automatic credit spend hides the point where the subscription stopped being enough.

4. 4

   Choose Ultra for Argon or capacity

   Choose Ultra 5x when you need Argon inside Antigravity or Pro repeatedly reaches its cap. Move to Ultra 20x when the additional 15 Pro-equivalent units can replace more than $100 of overage or blocked work. A company that needs governance should price the Gemini Enterprise business route and configure its project usage cap before rollout.

The result next Monday is one defensible budget choice: free while outcomes keep moving, $19.99 when weekly limits become a business cost, and Ultra when Argon access or measured capacity earns the jump.
