Amazon Q Developer vs Google Antigravity
Updated March 10, 2026
Overview
Amazon Q Developer is AWS's AI coding assistant that provides code suggestions, chat-based assistance, and autonomous code transformation capabilities. It can modernize Java applications, upgrade framework versions, and implement features across multi-file projects. Q Developer integrates with popular IDEs and has deep knowledge of AWS services, making it particularly useful for cloud-native development.
Google Antigravity is Google's agentic development platform, announced alongside Gemini 3 in late 2025. Built as a modified VS Code fork, it combines a traditional AI-powered editor with a Manager View for orchestrating multiple autonomous agents working in parallel across workspaces. Agents can plan, execute, and verify complex tasks across editor, terminal, and browser. Antigravity achieved 76.2% on SWE-bench Verified and supports Gemini 3 Pro, Deep Think, and Flash models, plus third-party models like Claude.
