A decision for a beginner, not a spec sheet. Scores are our weights. Prices are the public plans, and anything marked verify on the tool page should be re-checked before you pay.
Pick Amp if you want a repo you want an agent to work on in parallel, including while your laptop is closed.
Pick Google Antigravity if you are trying an editor agent without a subscription.
A coding agent you can run free on your own machine, or in Amp's cloud.

Individual
Free
VerifiedAll product features. No monthly fee. Pay-as-you-go orbs, or your own runners at no Amp charge. Linked ChatGPT, Claude, and other subscriptions, and bring-your-own-key, with no Amp token fees or limits. No included orb minutes and no included Amp credits.
The Hobby card is on ampcode.com/pricing. Standard orb rates, if you do use cloud machines, are on the orb sizes page and start at $0.08 an hour for a1.tiny.
Individual
$20/mo
Verified45,000 minutes of orb time and $20 of Amp credits, then more credits at provider list price. Unlimited public and private repositories, and your own portal domains. Soft hosting limits on the card are 1 GB of repository storage and 10 GB of monthly transfer.
This is the Individual price shown on the default pricing tab. Included usage does not roll over. The $20 of credits is the amount the pricing card prints for this tier.
Individual
$10/mo
VerifiedThe same Megawatt allowance, at $10 a month for students and teachers. The pricing card shows $10 of included Amp credits when the education discount is applied.
The pricing FAQ says students and teachers can get Megawatt for $10 per month. Left out of budget matching so a general under-$10 question cannot be won by a discount most readers cannot buy.
Individual
$200/mo
Verified480,000 minutes of orb time, which is the Gigawatt tab's minute figure, and $200 of Amp credits. The underlying allowance is 1,000 hours of a1.xxlarge. a1.3xlarge orbs are limited to Gigawatt and Enterprise. Soft hosting limits are 10 GB of repository storage and 100 GB of monthly transfer.
The $200 price is the Gigawatt tier on ampcode.com/pricing. The default tab is Megawatt, so the $200 card is the other Individual tab. A note on the orb details says 10× limits for Gigawatt.

Individual
Free
VerifiedUnlimited Tab and Command requests. Weekly agent quota. Gemini models, including Gemini 3.8 Flash, which the plans doc names as a core agent model. No published prompt count.
The Antigravity pricing page lists this at $0/mo.
Individual
$19.99/mo
VerifiedHigher Antigravity quota, refreshed every five hours until a weekly limit. AI credits can cover overage if you allow it. Also a Google One plan with storage and other Google AI benefits.
The dollar amount is the Google AI Pro price on Google One. Antigravity's own pricing page describes the higher limits and does not print $19.99.
Individual
$99.99/mo
VerifiedHighest Antigravity quota class, refreshed every five hours, plus third-party models. Google labels this 5x Pro Gemini usage.
Price is from Google One and Gemini subscription pages, which are the plans Antigravity docs say raise the quota.
Individual
$199.99/mo
VerifiedThe highest weekly limits Google documents for these plans, labeled 20x Pro Gemini usage.
Same source split as the 5x tier: quota rules on Antigravity docs, price on Google One.
Included Megawatt and Gigawatt usage resets at the end of the monthly billing period and does not roll over. Purchased credits expire 12 months after you buy them. A paused orb costs nothing. Amp pauses an idle orb 5 minutes after the agent stops, or 20 minutes after your last interaction, whichever is later.
On Hobby, use your own runner if the bill you are avoiding is orb time. Model limits on a linked ChatGPT or Claude subscription are that vendor's cap, not an Amp cap.
Free quota refreshes weekly. Google AI Pro refreshes every five hours until a weekly limit. Ultra refreshes every five hours and has the highest weekly limits. Prompt counts are not published because heavier tasks spend more quota.
On the free plan, wait for the weekly refresh. There is no credit overage.
Google Antigravity's cheapest paid plan the ranking counts is Google AI Pro at $19.99/mo. Amp's cheapest paid plan the ranking counts is Megawatt at $20/mo.
Amp is for a repo you want an agent to work on in parallel, including while your laptop is closed, people who already pay for ChatGPT or Claude and want to use that subscription inside an agent, and developers who can review agent output and do not need a hosted app builder.
Google Antigravity is for trying an editor agent without a subscription, gemini-first coding on a weekly quota, and a $20-ish step up via Google AI Pro if the free week runs out.
Amp scores 1 out of 5 for someone who does not want to read code. Google Antigravity scores 2 out of 5. Google Antigravity has the higher no-code score. You are starting threads against a project and reading what the agent did. This is not a no-code builder. Better than a pure terminal, and you are still in an IDE.
Amp: Free to Amp if you bring your own model subscription or key and run on your own machine. Cloud orbs are pay-as-you-go. Hobby includes no orb minutes and no Amp credits. Google Antigravity: Free. Unlimited Tab completions and Command requests, Gemini models, and a weekly agent quota. The quota is not a published prompt count. It refreshes weekly, not every five hours.
