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

Antigravity pricing starts at $0, with consumer Google AI plans at $4.99, $19.99, $99.99, or $199.99 a month. Since November 2, 2026, Free and Plus are Gemini-only for selectable reasoning models; paid Pro at $19.99 remains the sensible default for regular solo work, with Gemini 4 Argon and Claude 5.5 access. The two Ultra tiers buy 5x and 20x Pro quota, with the $199.99 tier offering better value per unit of published Gemini quota.

The Google prices, models, and plan labels below were verified on November 2, 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 (November 2, 2026)

Google AI Pro at $19.99 a month is the right paid starting point, including for Argon. Google now lists Argon on paid Pro subscriptions and Pro trials with eligible premium devices. Plus is too constrained for dependable agent work, Ultra 5x buys more headroom, 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.

Google's October 13, 2026 Argon announcement now lists Google AI Pro and Ultra subscribers alongside eligible Gemini Enterprise access. Paid Google AI Pro includes Argon in Antigravity; the current matrix also permits Pro trials with eligible premium devices. Argon runs in the Antigravity App, CLI, and IDE extensions. The standalone IDE also gained Argon for eligible tiers in version 2.6.0 on October 26, 2026. An individual no longer needs Ultra solely to select Argon.

The November 2, 2026 removal of Anthropic Claude Sonnet 4.6 (thinking), Claude Opus 4.6 (thinking), and OpenAI GPT-OSS-120b leaves Free and Google AI Plus Gemini-only. Paid Pro, Ultra, and Enterprise retain Anthropic Claude Sonnet 5.5 and Opus 5.5 thinking models. Google's model page still displays the retired rows with their November 2 cutoff; the table below applies that effective date to selectable reasoning models.

Pro trials are also Gemini-only, including the premium-device trials that qualify for Argon. Paid Pro, Ultra, and Enterprise did not become Gemini-only. No OpenAI reasoning model remains in this post-removal matrix. Enterprise Claude access requires administrator enablement and consumption billing.

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 or $199.99 billed annually, as shown on the US Google AI plans page, 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 more 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.

This tier buys capacity for someone who already likes the workflow and keeps reaching Pro's ceiling. Argon access alone is no longer a reason to upgrade from paid Pro. The published price and quota multiplier make this a headroom purchase, not a meaningful 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. Its published quota grows faster than its price relative to Pro. That improves value only if your work uses the extra allowance.

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.

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 paid subscription and Cloud Billing. Both self-serve online and invoiced accounts are supported; self-serve accounts pay for metered usage with prepaid credits. Free-trial subscriptions do not include AI developer tools.

Enterprise has its own included credit allowance. Google's quota documentation lists $10 per user per month for Standard and $15 for Plus, shared across Antigravity, Antigravity for IDEs, and Android Studio. Google enforces this as a rolling seven-day pool: the monthly per-user value divided by four, multiplied by licensed seats. Unused weekly quota does not roll over. This covers first-party Gemini usage; Claude is billed separately through pay-as-you-go charges. These are Enterprise developer-tool credits, distinct from consumer AI overage credits and the Developer Program's Google Cloud benefit.

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 & spend, 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. For prepaid usage, work stops when the credit balance reaches zero or the spend cap is reached, whichever happens first. 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. 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; the enterprise guide marks JetBrains, Zed, and Xcode support Preview. These are ways to access the product, not separately priced plans on the pricing page.

Teams on Gemini Code Assist Standard or Enterprise

Since October 9, 2026, new Gemini Code Assist Standard and Enterprise subscriptions are no longer sold. Google's release note says existing subscriptions auto-renew through 2026, with renewal ending in 2027. Its sunset page specifies that existing Code Assist subscriptions keep working and remain supported through the contract's end: adding seats and annual auto-renewals stop after January 31, 2027; monthly auto-renewals stop after December 31, 2027. Existing Gemini Enterprise subscriptions retain their Code Assist entitlement until March 31, 2027. Plan around the deadline for your own entitlement and contract.

Buy Antigravity through an eligible Gemini Enterprise subscription or the Gemini Enterprise Agent Platform API route. For subscriptions, confirm edition and billing eligibility, assign licenses and user permissions, and enable AI developer tools for the subscription's region. Eligible Standard/Plus seats need no separate per-user Antigravity license. For Agent Platform API access, Google's enterprise setup directs new customers to create an API key, select or create a Cloud project, activate billing, and enable aiplatform.googleapis.com; partner models require administrator enablement. Budget the applicable subscription and consumption charges described above.

These pages publish no special transition pricing or tooling to transfer Code Assist seats or contracts. The sunset page does link a Gemini CLI-to-Antigravity CLI migration guide; that is workflow guidance, not a promise of automatic seat conversion. Confirm eligibility and the replacement bill before the last renewal.

For Jules users: Google's shutdown notice, dated October 29, 2026, gives you until November 11 to finish sessions, followed by read-only access until the December 31 wind-down. Jules's background-coding work informs Antigravity, which offers asynchronous agent workflows, scheduled tasks, a CLI, and IDE extensions under the plans above. The notice promises no automatic history import, transfer of Jules task quotas, or special migration price. Export Jules-held context, then validate a replacement workflow against Antigravity's own model access and quota rules. Follow the Google Jules shutdown guide for the export and transition steps.

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 buys headroom; Ultra 20x offers the stronger quota value. Google's published multipliers compare Gemini token allowances with Pro. They do not promise a fixed number of agent jobs, and third-party models have separate limits.

• Pro: $19.99/month for the baseline paid allowance.
• Ultra 5x: $99.99/month for 5x Pro quota.
• Ultra 20x: $199.99/month for 20x Pro quota.

Choose the larger tier when the extra allowance replaces recurring overages or blocked work. Unused quota has a cost and no outcome. Paid Pro already includes Argon, so model access alone does not justify the Ultra jump.

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. Its plans documentation says those credits are consumed at standard Gemini Enterprise consumption pricing.

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. Google also excludes memberships billed through third parties, Pixel Pass, or Apple from credit purchases.

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 Antigravity credit balance unless the signed-in account shows one. The Google AI comparison lists separate Flow credit allowances; those are not a published Antigravity monthly credit grant.

Annual Pro billing: $199.99 upfront

Google confirms monthly and annual Pro subscriptions. The current US plans page displays $19.99 monthly or $199.99 annually in its Pro billing selector. Confirm the checkout total for your account before choosing a term. Ultra is billed monthly.

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

Antigravity competes on workflow and bundle value. Compare the model you will use and its usage charges alongside the subscription. Google AI Pro now publishes its annual total, so compare both the billing term and the usage rules.

Cursor: model choice changes the bill

Cursor now lists Plus at $8/month with Grok models only, and Premium at $30/month with cloud agents, automations, and access to third-party models billed separately at API list price.

Pick Cursor when its editor workflow and model options fit the job. Pick Antigravity when agent orchestration and the wider Google AI bundle matter more. The deeper Antigravity vs Cursor comparison should be a workflow decision, not a discount hunt.

Cursor's candid limit is that third-party models add a separate usage bill. Antigravity's candid limit is less transparent quota accounting. Compare the model you intend to use, not just the lowest subscription price.

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. Google AI Pro lists $199.99 annually, making their published annual subscription totals nearly equal. Their model access and usage rules decide which fits your work.

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. It includes unlimited code completions and next-edit suggestions, $15 in monthly AI credits currently made up of $10 base credits plus a variable $5 flex allotment, model selection, and preview access to third-party agents including Claude by Anthropic and OpenAI 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 Plus at $8 with Grok only, or Premium at $30 plus third-party usage for an editor-first workflow, and Antigravity Pro at $19.99/month for agent-first work plus the Google bundle. Paid Antigravity Pro now includes Argon; upgrade to Ultra for measured capacity needs.

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 without a meaningful unit-cost saving, while the top tier offers more quota for the money.

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 or you need the Claude models that Free and Plus no longer offer. Plus is not a dependable agent upgrade because requests remain limited and it cannot buy overage credits. Paid Pro now includes Argon inside Antigravity, with a trial exception for eligible premium devices. Ultra is worth considering when measured Pro usage reaches its ceiling.

Is there anything better than Antigravity?

Cursor offers an editor-first alternative: Plus is $8/month with Grok only; Premium is $30/month with third-party models billed separately. Claude Code is terminal-first at $20/month or $200/year through Claude Pro. GitHub Copilot Pro is a completion-first 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 also advertises Google AI Pro free for one year for eligible students, with availability varying by country. Check your account's offer terms, and do not assume a student trial includes the Claude models reserved for non-trial Pro subscriptions.

Does Antigravity have annual pricing?

Yes. The current US Google AI plans page displays Pro at $199.99 annually or $19.99/month. Confirm your account's checkout terms. Ultra is billed 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: Free and Plus now offer Gemini 3.8 Flash only. Paid Pro qualifies for Argon and Claude 5.5; a Pro trial needs an eligible premium device for Argon and does not include Claude 5.5. Otherwise, the goal is to measure a blocked outcome, not to guess how impressive an allowance sounds.

1. 1

   Start on Individual

   If Gemini 3.8 Flash covers your work, 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 capacity

   Choose Ultra 5x when Pro repeatedly reaches its cap. Move to Ultra 20x when its larger allowance can replace enough overage or blocked work to justify the higher bill. 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 measured capacity earns the jump.
