Google Antigravity Explained: What It Is, What You Can Build With It, and What You Need to Know

The business is looking to implement and utilize new AI tools and create some worker Agents create web and mobile apps so we are trialing Antigravity.

Antigravity is Googles AI Agent platform that can plan, execute and verify complex tasks including websites and mobile apps. 

This guide explains what it does, how much it costs and where we get started.

What is Google Antigravity?

Googles Antigravity is an agentic development platform.

Traditional coding assistants generally wait for you to write code and ask for help with a specific piece of it. An agent can instead be given a higher-level objective and carry out multiple steps to achieve it.

For example, instead of asking:

“Write a simple login screen.“

you could give an agent a task such as:

“Create a simple login flow with email/password authentication, validation, loading states and error handling. Run the tests and fix any problems you find.”

The agent can then work through the project rather than simply returning a piece of code.

Google describes Antigravity as an environment where agents can operate across the editor, terminal and browser, with an emphasis on completing tasks and verifying their work.

Antigravity can therefore be thought of as an AI development environment and agent platform, rather than simply an AI chatbot that writes code.

What can Antigravity be used for?

Antigravity is software development and agent platform.

Some common uses include:

  • Building websites
  • Creating web applications
  • Building backend services and APIs
  • Creating mobile applications
  • Working with existing codebases
  • Debugging applications
  • Writing and running tests
  • Refactoring code
  • Researching technical problems
  • Automating repetitive development tasks
  • Working with Git repositories
  • Using external tools through MCP servers and skills
  • Running multiple agents on different tasks
  • Performing browser-based testing
  • Generating implementation plans and other artifacts

Google specifically highlights frontend, full-stack and enterprise development as Antigravity use cases.

Is Antigravity an AI coding assistant?

Yes, but that description doesn’t really capture what it does.

A conventional AI coding assistant might help you write a function.

An Antigravity agent can potentially:

  1. Understand the project.
  2. Work out how a feature should be implemented.
  3. Create or modify multiple files.
  4. Run commands.
  5. Run tests.
  6. Inspect the results.
  7. Fix problems.
  8. Continue iterating.
  9. Produce an artifact explaining what it did.

This is why Google calls it an agentic development environment.

The distinction becomes particularly important for larger tasks.

Instead of having a conversation about dozens of individual coding changes, you can give the agent a goal and allow it to work through the implementation.

What is an "agent"?

An agent is the AI worker that performs the task.

You give it an objective, and it can use the tools available to it to work towards that objective.

Depending on the environment and configuration, those tools can include:

  • Reading files
  • Writing files
  • Editing code
  • Running terminal commands
  • Searching the web
  • Interacting with a browser
  • Using external services
  • Running tests
  • Working with Git
  • Creating artifacts

Antigravity can also run multiple agents or subagents, allowing different tasks to be worked on in parallel.

That can be useful for larger projects.

For example, one agent could investigate an authentication problem while another works on the user interface.

What are Projects in Antigravity?

Projects provide the environment in which an agent works.

Google’s documentation explains that Projects define the folders and repositories an agent can access.

You can associate one or more local folders or Git repositories with a Project, giving the agent context about the code it is working on.

This is important because AI agents are much more useful when they can understand the whole project, rather than being given isolated pieces of code.

What are Skills and MCP servers?

One of the most useful concepts to understand is that Antigravity can be extended.

Agents don’t have to be limited to the capabilities built into the application.

Antigravity supports external tools through things such as skills and MCP servers.

Think of these as additional capabilities you can give an agent.

For example, a project might use:

  • Firebase
  • Supabase
  • GitHub
  • Figma
  • Databases
  • Cloud services
  • APIs
  • Browser automation

The exact tools you need depend on what you are building.

You do not need to install every available plugin.

In fact, installing unnecessary tools can make a project more complicated.

A good rule is:

Install capabilities because your project needs them, not simply because they are available.

Antigravity build iPhone and iPad apps

Antigravity can be used as part of an iOS development workflow.

However, there is an important distinction.

Antigravity is the AI development environment. Apple’s development tools are still required for native iOS development.

For a typical SwiftUI application, you would normally work with:

  • macOS
  • Xcode
  • Swift
  • SwiftUI
  • Apple’s iOS SDK
  • iOS Simulator
  • Antigravity

Antigravity can help write and modify the application, while Xcode provides Apple’s official build, simulator, debugging and signing environment.

This means you shouldn’t think of Antigravity as a replacement for Apple’s development ecosystem.

Instead, think of it as an AI agent that can work alongside it.

Can you use it without coding knowledge?

Yes.

This is one of the most interesting things about agentic development.

Someone with relatively little programming experience can describe an application in natural language and ask Antigravity to build it.

However, there is an important catch.

You don’t need to be an expert programmer, but you should understand what the agent is doing.

If you don’t understand anything about:

  • Programming
  • Databases
  • APIs
  • Authentication
  • Security
  • Git
  • Testing
  • Application architecture

It becomes much harder to tell whether the agent has produced a good solution.

AI can write code that looks convincing while still being incorrect.

The more important your application is, the more valuable it becomes to understand the fundamentals.

What should you learn before using Antigravity?

You don’t need to learn everything about software development first.

A useful starting point is to understand these concepts.

1. Files and folders
Understand how a software project is structured.

2. Git
Learn the basics of:

  • Commits
  • Branches
  • Reverting changes
  • Pulling changes
  • Pushing changes

Git gives you an important safety net when an agent makes changes.

3. Programming fundamentals
You should understand:

  • Variables
  • Functions
  • Conditions
  • Loops
  • Objects/types
  • Errors
  • Async operations

You don’t need to be an expert.

4. APIs
Understand what an API is and how applications communicate with servers.

5. Databases
Understand the basic concepts of:

  • Tables
  • Records
  • Relationships
  • Queries
  • Authentication
  • Permissions

6. Security
This is particularly important.

Never blindly accept an agent’s implementation of authentication, payments, permissions or handling of sensitive information.

7. Testing
Learn how to ask an agent to test its work and understand what the tests are actually testing.

How should you talk to Antigravity?

The quality of your instructions matters.

A vague instruction might be:

Build me an app.

A much better instruction describes:

  • What the application does
  • Who uses it
  • The platforms it supports
  • The important screens
  • The data it stores
  • Authentication requirements
  • External services
  • Design requirements
  • Technical constraints
  • How success should be tested

For example:

Build a SwiftUI iPhone application for managing household tasks. Users should be able to create an account, create tasks, assign tasks to household members and mark tasks as complete. Use Supabase for authentication and the database. Use a clean native iOS design. Create unit tests for the task-management logic and run the tests after implementation.

That’s considerably more useful than:

Make me a task app.

Use an agent as a developer, not a magic button

One of the biggest mistakes beginners make is giving an AI agent an enormous task and expecting a perfect application at the end. A better approach is iterative. For example:
  1. Define the application.
  2. Create the project structure.
  3. Build the first screen.
  4. Review it.
  5. Add authentication.
  6. Test authentication.
  7. Add the database.
  8. Test the database.
  9. Add the next feature.
  10. Test again.

This makes problems easier to identify and fix.

It also gives you much more control over what the agent is changing.

What are Artifacts?

Antigravity uses Artifacts to communicate structured results from agents.

Artifacts can include things such as:

  • Plans
  • Code changes
  • Architecture diagrams
  • Images
  • Browser recordings
  • Other structured deliverables

Google describes artifacts as part of Antigravity’s approach to making agent work more transparent and easier to review.

This is useful because you don’t necessarily want an agent to silently make dozens of changes.

You want to be able to understand what it did.

Can Antigravity work autonomously?

Yes.

This is one of its defining characteristics.

Antigravity supports agents that can work asynchronously, and Antigravity 2.0 is designed as a command centre for managing agents performing longer-running tasks.

The idea is that you can give an agent a task and let it work through multiple steps.

However, autonomy should not be confused with correctness.

An autonomous agent can make mistakes autonomously too.

For important projects, review its changes, run tests and use version control.

How much does Antigravity cost?

Antigravity currently has a free individual option.

Google’s current pricing page lists:

  • Individual — $0/month
  • Google AI Pro — paid subscription with higher limits
  • Google AI Ultra — paid subscription with higher limits and additional capabilities
  • Organization — available through Google Cloud

The free plan includes access to agent models, unlimited Tab completions, unlimited command requests and basic weekly rate limits.

The exact subscription prices and entitlements can change, so check Google’s current pricing page before purchasing a plan.

Is the free version actually usable?

Yes, but there are limits.

Antigravity’s free tier has usage/rate limits.

Google explains that the limits are based primarily on the amount of work an agent performs rather than simply counting every message equally.

A straightforward task may therefore consume considerably less quota than a complicated task requiring extensive reasoning, tool usage and iteration.

For occasional experimentation, the free tier can be enough.

People using Antigravity heavily as a daily development environment may encounter the limits more quickly.

What are Google AI Pro and Ultra?

Google’s paid AI plans provide higher Antigravity usage allowances.

Google currently describes Pro as providing more generous rate limits, while Ultra provides the highest quotas and access to additional capabilities, including third-party models.

The important point is that paying for a higher plan doesn’t mean the agent becomes magically better at software development.

The major benefit is generally more capacity and access to additional models/features.

Are there usage limits?

Yes.

This is one of the most important limitations to understand.

Antigravity isn’t an unlimited AI developer that can run indefinitely without restrictions.

Google states that rate limits vary according to plan and usage, and that limits can change depending on system capacity.

The amount of work an agent performs can also affect how quickly you reach those limits.

Frequently Asked Questions

Is Google Antigravity free?

Yes. Google currently offers a free individual tier with basic weekly rate limits. Paid Google AI plans provide higher usage allowances.

Does Antigravity require a Google account?

Implement the project structure and basic user interface. Run the appropriate tests and explain any problems you encounter.

Can Antigravity build iOS apps?

It can assist with building native iOS applications, but you still need Apple’s development tools, including Xcode, for the native iOS build and deployment workflow.

Do I need to know programming?

No, but learning programming fundamentals will make you substantially better at directing and checking an AI coding agent.

Can Antigravity replace a developer?

It can automate significant parts of software development, but it doesn’t eliminate the need for technical judgement, testing, security review and project management.

Does Antigravity have usage limits?

Yes. Usage depends on your plan and the amount of work performed by agents.

Can I use my own API key?

Google currently says Antigravity doesn’t support bringing your own key or endpoint for additional rate limits.

Can Antigravity use Claude?

Yes. Google currently lists Claude Sonnet 4.6 and Claude Opus 4.6 among the models available in Antigravity, with availability depending on the plan.

Can Antigravity use GPT?

Google currently lists GPT-OSS-120B as an available model. Model availability can change over time and depends on the relevant plan.

What are MCP servers?

MCP servers provide a standard way for agents to connect to external tools and services. They can extend what an Antigravity agent is capable of doing.

What are Antigravity plugins?

Plugins can package additional capabilities such as skills, MCP servers, rules and agents. They are optional and should generally be installed according to the requirements of your project.

Is Antigravity the same thing as ChatGPT?

No. Although both use AI models, Antigravity is specifically designed around agentic development and software-building workflows.

Is Antigravity the same as an IDE?

The original Antigravity IDE is an agentic development environment. Antigravity 2.0 has evolved into a standalone agent command centre, while Google continues to provide development-focused tooling such as the IDE and CLI.

Can Antigravity deploy my application?

It can assist with deployment tasks where the necessary tools and credentials are available, but deployment platforms, Apple, Google Play, cloud providers and other services retain their own requirements and restrictions.

Is Antigravity suitable for professional development?

Yes. Google positions Antigravity for professional, full-stack and enterprise development as well as hobbyist use.

What is the biggest mistake beginners make?

Treating the AI as infallible.

The best results come from treating the agent as a very capable development partner whose work still needs direction, verification and review.

Conclusion

Google Antigravity represents a shift from AI that merely helps you write code towards AI that can perform software-development tasks.

That distinction is important.

You can give an agent a goal, provide it with access to your project and tools, and allow it to perform a sequence of development tasks rather than manually directing every individual coding change.

For experienced developers, that can mean automating a significant amount of repetitive work.

For beginners, it can make software development considerably more accessible.

But the fundamentals still matter.

The most effective Antigravity users aren’t necessarily the people who know every programming language.

They’re the people who can:

  • Clearly describe what they want.
  • Break large problems into smaller ones.
  • Give the agent the right tools.
  • Understand the technology being used.
  • Review what the agent produces.
  • Test the results.
  • Recognise when something looks wrong.
  • Keep control of their codebase.

The future of AI-assisted development isn’t necessarily about replacing the developer.

It’s about changing what the developer spends their time doing.

Instead of typing every line of code, you increasingly direct, supervise, test and refine intelligent agents that can write much of the code for you.

Context matters

Poor project organisation can make AI-assisted development harder.

Agents can make unwanted changes

This is why version control and reviewing diffs are important.

Usage limits exist

External services still have their own requirements

You still need to test
