Best For

Developers who want an agent first IDE where AI agents are the primary development interface, not an afterthought

Verdict

The free Individual tier is genuinely generous, offering all AI models, unlimited Tab completions, and the full feature set with no credit card required.

What it does

Agent First Development

The entire IDE is designed around agents as the primary development interface. Rather than adding AI to a code editor, Antigravity builds the editor around the agent workflow.

Learn more

Manager Surface

A dedicated orchestration interface for managing multiple agents working simultaneously. Monitor progress, assign tasks, review artifacts, and coordinate agent work across your project.

Learn more

Built in Browser

Agents have access to a built in browser for testing web applications, verifying UI changes, and debugging visual issues without leaving the IDE.

Artifacts Verification System

Every piece of agent output goes through the Artifacts system, where you can review diffs, approve changes, request modifications, or reject output before it touches your codebase.

Multi Model Support

Use Gemini 3.5 Flash, Gemini 3.1 Pro, Gemini 3 Flash, Claude Opus 4.6, Claude Sonnet 4.6, and gpt-oss-120b. Switch between models based on the task at hand.

Learn more

Unlimited Tab Completions

Inline code completions powered by Gemini models, available on all tiers with no usage caps. Fast, context aware suggestions as you type.

Inline Commands

Highlight code and describe the change you want. The agent rewrites the selected code inline, similar to Cursor's Cmd+K but integrated with the Artifacts verification flow.

Learning and Knowledge Base

Teach the IDE your codebase conventions, architectural decisions, and team standards. The knowledge base persists across sessions and informs all agent interactions.

Google Cloud Integration

Native MCP servers for BigQuery, Spanner, Cloud Run, Cloud Storage, and other Google Cloud services. Query databases, deploy services, and manage infrastructure directly from the IDE.

Firebase Integration in AI Studio

Full stack development through AI Studio with native Firebase support. Agents can provision databases, configure authentication, set up hosting, and deploy backend services, turning Antigravity into a complete application development platform.

AGENTS.md Support

Configure agent behavior through an AGENTS.md project level configuration file. Define coding conventions, architectural constraints, preferred libraries, and task specific instructions that all agents in the project follow automatically.

Cross Platform

Available on macOS, Windows, and Linux. Full feature parity across all platforms with native performance.

Feedback on Artifacts

Provide structured feedback on agent output. Accept, reject, or request changes with inline comments. The agent learns from your feedback to improve future output.

Agent Sidebar

A persistent sidebar for conversational interaction with the agent. Ask questions about your codebase, request explanations, or start new tasks without leaving your current file.

Pros & Cons

Pros

  • The free Individual tier is genuinely generous, offering all AI models, unlimited Tab completions, and the full feature set with no credit card required.
  • The Manager Surface is unique among AI IDEs, providing a dedicated interface for orchestrating multiple agents working simultaneously on different parts of a project.
  • Built on VS Code, so extensions, themes, keybindings, and muscle memory carry over from VS Code or Cursor with minimal adjustment.
  • Multi model support includes Gemini, Claude, and GPT models, letting you pick the best model for each task without switching tools.
  • The Artifacts verification system gives developers explicit control over what agent output enters the codebase, reducing the risk of unchecked AI changes.
  • Native Google Cloud MCP integrations make it the natural choice for teams already using BigQuery, Spanner, Cloud Run, and other GCP services.

Cons

  • Newer than Cursor and Claude Code, so the ecosystem of community extensions, rules, and shared configurations is still maturing.
  • The agent first paradigm has a learning curve for developers used to traditional code editors. The Manager Surface requires understanding a new mental model.
  • The Organization tier is available only through Google Cloud's Gemini Enterprise Agent Platform, which may not suit teams that do not use the Google ecosystem.
  • As a VS Code fork (like Cursor), it can lag behind upstream VS Code updates and occasionally has compatibility issues with certain extensions.
  • AI credits have been removed from base plans (now used only as an overage mechanism for Pro and Ultra subscribers), which simplifies billing. However, the shared quota system where Gemini Flash and Pro models draw from one pool (at different rates per API pricing) still requires users to think about model cost tradeoffs when budgeting their usage.
  • Rate limits on the free Individual tier, while generous compared to most competitors, can still be hit during intensive agent sessions. The weekly rate limit structure means the amount of work you can do depends on which models you use and how complex the tasks are.

How to get started

1

Download Antigravity

Visit antigravity.google and download the installer for your platform (macOS, Windows, or Linux). The IDE installs like any standard desktop application.

Download Antigravity
2

Import your VS Code setup

On first launch, Antigravity offers to import your VS Code or Cursor extensions, themes, keybindings, and settings. Accept the migration to preserve your existing workflow.

3

Sign in with your Google account

Sign in with your Google account to activate the Individual tier (free). If you have a Google AI Pro or AI Ultra subscription, the higher rate limits activate automatically.

4

Explore the two surfaces

Familiarize yourself with the Editor View (traditional coding with AI assistance) and the Manager Surface (multi agent orchestration). Toggle between them using the surface switcher in the top bar.

5

Start an agent task

Open the Agent Sidebar and describe a task in natural language. The agent plans the approach, writes code, and presents the result as Artifacts for your review. Approve, reject, or request changes before the code enters your project.

6

Try the Manager Surface for parallel work

Switch to the Manager Surface and assign multiple tasks to different agents. Monitor their progress, review artifacts from each agent, and merge approved changes into your codebase.

7

Set up your Knowledge Base

Create a knowledge base with your team's conventions, architectural decisions, and coding standards. This context persists across sessions and improves the quality of all agent interactions.
