Antigravity Plans and Pricing: Free Tier, Rate Limits and Parallel Agents
By CodeAgentSwarm · Updated September 1, 2026
The plans at a glance
Antigravity access is bundled into Google AI subscriptions rather than sold separately. As of August 2026 the ladder looks like this:
| Plan | Price | What changes |
|---|---|---|
| Individual (free) | $0 | All models, basic weekly rate limits |
| Google AI Plus | Around $8/month | Expanded Antigravity requests |
| Google AI Pro | $20/month | More generous rate limits, flexible credit pool |
| Google AI Ultra 5x | $100/month | Higher Antigravity requests |
| Google AI Ultra 20x | $200/month | Highest Antigravity requests |
| Organisation | Via Google Cloud | Consumption-based API pricing |
Google does not publish the monthly prices on the Antigravity pricing page itself, which lists the tiers and their features but leaves the numbers to the Google AI subscription pages. The figures above are consistent across sources as of August 2026, but this is the one table in this guide you should verify against your own Google account before paying, not least because Google has repriced this ladder at least once already.
The live Google One ladder now names the two top plans Google AI Ultra 5x and Google AI Ultra 20x. Older comparisons may call the $200 tier Ultra Max or quote $250; use the current Google account checkout before buying.
Google now describes Antigravity access as limited, expanded, higher and highest across the ladder. That wording is relative rather than a published request count, so choose a plan from the usage shown in your account instead of converting the 5x and 20x plan names into invented quotas.
The free tier: what it allows, and what has been taken away
The free plan is unusually generous on paper. It carries access to multiple frontier models, including Gemini and Claude models, plus unlimited tab completions and unlimited command requests. The gate is weekly rate limits on agent requests, not a feature wall.
That combination is genuinely unusual. Most free tiers restrict you to the vendor's cheapest model; Antigravity's does not. For evaluating whether an agentic workflow suits you at all, it is the best free option in the category.
Free tier limits have been cut repeatedly since Antigravity launched in November 2025, and the reductions have been steep rather than incremental. Whatever the current daily or weekly request allowance is when you read this, treat it as a snapshot rather than a commitment, and do not build a team workflow that depends on the free tier staying where it is.
The honest way to read that history: Google is still finding the sustainable level for giving away frontier-model agent access, and it has adjusted downward each time it found the answer was "less than this". That is not a criticism of the product, it is a reason to plan for the free tier shrinking rather than growing.
The practical consequence for anyone running several agents: the free tier is sized for one person driving one agent thoughtfully. It is not sized for the parallel-agent pattern, and you will notice that within a session.
The credit pool: what happens past the included quota
Google documents extra AI credits for Pro and Ultra users after the included quota runs out. The amount deducted follows standard API pricing and varies by model and task complexity, so there is no reliable flat $0.01 conversion for every Antigravity request.
This puts Antigravity in the same broad category as Codex and paid Claude plans: you can fund work beyond the included quota instead of always waiting for a reset. Whether that is good news depends on whether you budgeted for it.
The rule of thumb transfers too: if you are buying credits regularly, the next tier up is almost certainly cheaper than the habit. Credits are priced for convenience, not for volume.
The free tier has no credit pool. When the free rate limits are exhausted, you wait.
What running several Antigravity sessions at once does to the cost
Antigravity meters you on weekly rate limits rather than on a running bill, so parallel agents do not produce a bigger invoice. They produce an earlier wall. Every agy session draws from the same account allowance, so the limit arrives in proportion to how many of them are actually working.
What happens at that wall depends on your plan. Pro and Ultra can keep going on the credit pool, which follows standard API pricing and varies by model and task complexity. The free tier has no credit pool at all, so when the weekly limits are exhausted every session stops and you wait for the reset.
| Sessions at once | What to expect | What to watch |
|---|---|---|
| 1 | This is roughly what the free tier is sized for: one person driving one agent thoughtfully. | Little. You feel the weekly rate limits only in a heavy week. |
| 2 to 3 | The weekly rate limits arrive around two to three times sooner than with a single session. | On the free tier this is where the limits start to bite mid-session, with no credits to fall back on. |
| 4 or more | The parallel-agent pattern is not what the free tier is sized for, and you notice it inside a single session. | On Pro and Ultra the overflow lands on credits priced by model and task complexity, so budget for them or move up a tier. |
How to split work across those sessions is in the Antigravity agent swarm guide, and the setup itself is in how to run multiple Antigravity CLI sessions.
The visibility problem, and one thing it breaks
Antigravity is metered on rate limits rather than on a running bill, which makes knowing your position more important than it is on a pay-per-token agent. Running out is a stop, not a charge.
There is a specific gotcha here worth flagging, because it costs people real debugging time. Antigravity exposes its state through a local language server, and a logged-out session is externally indistinguishable from a session that is not running at all. Any tool reading that state, including Antigravity's own integrations, will report "not running" when the truthful answer is "running, but your credentials expired".
If your quota display suddenly reports Antigravity as off while you can see the agent working in front of you, check whether you are still logged in before you go looking for a bug. That failure mode is by far the most common cause, and it is invisible from the outside.
The same architecture makes quota reading platform-sensitive: the discovery mechanism that finds the local server differs between macOS, Linux and Windows, and tooling that assumes Unix process utilities will simply report nothing on Windows rather than failing loudly. If quota shows on one of your machines and not another, that is usually the reason rather than an account problem.
How Antigravity pricing compares
Put side by side with the other CLIs in this category, Antigravity occupies a clear position at the entry end and a less distinctive one above it.
- Against Claude Code: Antigravity wins decisively at $0, because Claude Code has no free tier at all. At $20 against $20 the comparison becomes about the models and the agent rather than the price.
- Against Codex: similar structure, both metered with a credit top-up. Codex undercuts on the entry paid tier thanks to its $8 Go plan; Antigravity wins on the free tier.
- Against OpenCode: different philosophies entirely. Antigravity gives you a bounded free allowance with no bill; OpenCode gives you an unbounded bill with no wall. Bursty work suits OpenCode, predictable work suits Antigravity.
The genuinely useful takeaway is that Antigravity is the best free option and a middling paid one. Use the free tier to evaluate agentic coding without committing to anything, and make the paid decision on the merits of the agent rather than on price, because at $20 and $100 the whole category charges roughly the same.
| Agent | Free tier | Cheapest paid | Top individual tier | How you are billed |
|---|---|---|---|---|
| Claude Code | No (Free plan has no Claude Code) | Pro, $20/month | Max 20x, $200/month | Subscription with 5 hour and weekly windows; API tokens optional |
| Codex CLI | Limited | Go, $8/month | Pro, $200/month | ChatGPT subscription shared with web and IDE; API tokens optional |
| Kimi Code | CLI is free, model usage is not | Andante, ¥49/month | Allegro, ¥699/month | Membership with weekly and 5 hour limits; API per token |
| OpenCode | CLI is free and open source | None, pay as you go | None | Your own provider key, or OpenCode Zen prepaid per token |
| Antigravity | Yes, with weekly rate limits | Google AI Plus, around $8/month | Google AI Ultra 20x, $200/month | Google AI plan with rate limits and credits |
| Grok Build | Yes, limited usage | SuperGrok, $30/month | SuperGrok Plus, $100/month | xAI plan rate limits; API per token |
| Cursor Agent | Hobby, free | Pro, $20/month | Ultra, $200/month | Cursor plan with usage pools per model |
Every number in that table has its own page with the full tier list and the fine print: Claude Code, Codex, Kimi Code, OpenCode, Grok Build and Cursor CLI.
Watching Antigravity quota while agents run
On a rate-limited plan, the wall arrives without warning and stops the agent mid-task. With one terminal that is an interruption. With several it means working out which sessions stopped, where each one got to, and whether any of them left a change half-applied.
CodeAgentSwarm, the desktop workspace for running several AI CLI agents in parallel, reads Antigravity's real quota from its local endpoint and shows it alongside your other agents' usage, with the platform-specific discovery handled for you on macOS and Windows. You see the wall approaching while the agents work.
It pairs with the mitigation that actually works on a free or Pro plan: keep a second agent on a different meter for overflow. Antigravity, Claude and Codex bill from entirely separate pools, so exhausting one rarely stops the session, which is the pattern in the Antigravity agent swarm guide.
FAQ
Yes, genuinely. The free tier gives access to multiple frontier models, unlimited tab completions and unlimited command requests, gated by weekly rate limits rather than by feature. It is the most usable free tier in this category, though the limits have been reduced repeatedly since launch.
There is no Antigravity subscription. Access comes with a Google AI plan: free, Plus from around $8/month, Pro around $20/month, Ultra 5x around $100/month and Ultra 20x around $200/month. Verify the current price in your Google account before paying.
Google has changed this several times since the November 2025 launch, always downward, so any specific number dates quickly. The structure is weekly rate limits on agent requests with unlimited tab completions and command requests. Check your account for the current allowance rather than trusting an article, including this one.
Pro and Ultra users can buy extra AI credits after the included quota runs out. Consumption follows standard API pricing and varies by model and task complexity, rather than one fixed price per request. Free users wait for the limit to reset.
Most often because your session is logged out. Antigravity exposes its state through a local language server, and a logged-out session looks externally identical to no session at all. Check that you are still signed in before assuming the tool is broken.
At the free tier, decisively yes, because Claude Code has no free tier. At the paid tiers the two are priced almost identically ($20 and $100), so the decision should be about the models and the agent rather than the bill.
There is no Antigravity subscription. Access rides on a Google AI plan: free, Plus at around $8/month, Pro at $20/month, Ultra 5x at $100/month and Ultra 20x at $200/month, plus an organisation route through Google Cloud priced by consumption. Google does not publish these prices on the Antigravity page itself, so verify them in your Google account before paying.
No. The free tier already gives access to multiple frontier models, unlimited tab completions and unlimited command requests, gated by weekly rate limits rather than by feature. Pro raises those limits and adds the credit pool that lets you keep working past the included quota.
They all draw from the same account allowance, so the weekly rate limits arrive sooner in proportion to how many sessions are actually busy. On Pro and Ultra the overflow goes to credits. On the free tier there is no credit pool, so every session stops until the limit resets.
