What is Google Antigravity?
Google Antigravity helps developers edit project files, run commands and execute tests. It also supports coordinating multiple development agents, checking applications in a browser and reviewing agent changes and reports.
According to its documentation, Google Antigravity lets you:
- edit project files with an agent
- run commands and tests
- check an application in the browser
- coordinate multiple development agents
- review agent changes and reports
We file it under AI coding assistants, the category of tools to write and fix code, and it also overlaps with aI agent builders and developer tools. The category lists 31 verified tools on this site.
The service launched in 2025.
Who is it for?
It is mostly useful to these profiles: developers. The need it covers is simple to state: write and fix code.
Google Antigravity is a good candidate if:
- you want to try before paying
- you plan to connect it to your tools or automations through its API
The best test is a concrete case from your daily work: if the tool does not beat your current method within a week, move on to an alternative.
How much does Google Antigravity cost?
Pricing model: freemium (limited free use, then paid). A free plan is offered, usually limited in volume or features.
The first paid plan costs $19.99 per month (Google AI Pro, standard monthly price displayed in USD; increases Antigravity quotas), according to the pricing page, checked on October 24, 2026.
Per month, that is more expensive than the category median ($15 per month, based on tools with a published price).
To estimate what the same work would cost done directly with an AI model, use our API price calculator. Prices change often: always check the official site before subscribing.
Data and privacy
According to its privacy policy, data is processed in several regions depending on the plan.
No export feature is documented: keep a copy of your content elsewhere.
Three habits apply to every AI tool:
- turn off the use of your content for training if the option exists
- use a work account separate from your personal account
- review everything the tool produces before publishing or sending it
Platforms, languages and API
Google Antigravity runs on: Windows, macOS, Linux, browser extension, and API.
Interface languages: English.
A public API lets you call it from your own programs or an automation tool, and plug it into an AI agent.
