Metrics Comparison

Autonomy

GitHub Copilot: 3

GitHub Copilot lacks autonomous agent capabilities and primarily functions as an intelligent autocomplete tool. It provides code suggestions and completions that require human intervention and decision-making. While it can suggest code patterns and generate code based on context, it does not independently execute tasks or make autonomous decisions about codebase modifications.

Google Antigravity: 9

Google Antigravity features full multi-agent orchestration with true autonomous agent capabilities. It can work independently on tasks, perform multi-file refactoring and complex changes, and autonomously create or alter files, run commands, introduce new functionalities, resolve bugs, and modify codebases. Multiple agents maintain shared context across workspaces and can work together efficiently on different parts of a large codebase simultaneously.

Autonomy represents the most significant differentiator between these tools. Google Antigravity is fundamentally designed as an agentic platform with autonomous task execution, while GitHub Copilot is fundamentally a suggestion engine requiring human direction for each action.

Ease of Use

GitHub Copilot: 9

GitHub Copilot excels at ease of use through its integration with every major IDE and editor (Visual Studio Code, Visual Studio, JetBrains IDEs, Neovim, Xcode, Eclipse, Azure Data Studio). Inline code suggestions are non-intrusive and natural to the development workflow. Developers can use Copilot without changing their existing development environment or learning new interfaces. The tool provides instant suggestions that feel like an extension of natural coding practices.

Google Antigravity: 7

Google Antigravity operates as a standalone AI-native IDE with a dual interface (Editor View and Manager View) and task-oriented workflows that enable developers to focus on high-level architecture while agents handle implementation. Natural language interaction with agents and artifact-based verification systems foster transparency. However, as a new standalone IDE, it requires users to adopt a new development environment rather than integrating into existing workflows.

GitHub Copilot wins on ease of use due to its ubiquitous IDE integration and non-disruptive inline suggestions, while Google Antigravity requires adoption of a new standalone IDE but may provide more structured workflows once users adapt to the environment.

Flexibility

GitHub Copilot: 8

GitHub Copilot provides flexibility through support for dozens of programming languages, multiple AI models (Claude 3.5 Sonnet, GPT-4.1, Claude 3.7/4 Sonnet, Gemini 2.5 Pro, Claude Opus 4, o3 depending on plan tier), and integration with virtually every major IDE and editor. It works with any codebase and development workflow. GitHub-specific features like pull request summaries and issue analysis add flexibility for GitHub-centric teams. However, it is primarily constrained to code completion rather than autonomous task execution.

Google Antigravity: 8

Google Antigravity offers significant flexibility through multi-model support (Gemini 3 Pro, Claude Sonnet 4.5, GPT-OSS), multimodal capabilities (code, images, design mocks), and custom rules system (.antigravity files) for enforcing team-specific coding standards. It handles complex refactoring tasks, multi-file changes, and end-to-end feature development. The agentic architecture allows flexible task orchestration and autonomous planning. However, as a standalone IDE, it has less flexibility for developers requiring specific existing IDE features.

Both tools offer high flexibility on different dimensions: Google Antigravity excels in task automation and multimodal development, while GitHub Copilot excels in IDE compatibility and language support. Flexibility choice depends on whether you prioritize agentic capabilities or IDE integration.

Cost

GitHub Copilot: 6

GitHub Copilot requires paid subscriptions: $10/month for individual developers ($20/month billed annually) or enterprise plans for teams with additional costs. GitHub Copilot for Business offers enterprise features with organization-wide billing. While individual pricing is moderate, it represents an ongoing monthly cost compared to free alternatives. The free tier (GPT-4.1) offers limited capabilities compared to paid Pro ($20/month) and Pro+ tiers.

Google Antigravity: 10

Google Antigravity is completely free during its beta period for individual developers, offering a significant cost advantage. No subscription fees or premium tiers are currently required, making it the most cost-effective option for developers seeking autonomous development capabilities. This free access during beta represents exceptional value proposition for early adopters.

Cost clearly favors Google Antigravity with free beta access versus GitHub Copilot's $10-20/month subscription. However, GitHub Copilot's cost-benefit ratio may justify the expense through time savings and productivity gains for professional developers coding 30+ minutes daily.
