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, with an agent-first IDE, a terminal CLI, and Antigravity 2.0 for running multiple coding agents in parallel.
