Amazon Q Developer (successor to CodeWhisperer) is AWS’s coding assistant: inline suggestions and agentic chat in IDEs and the CLI, security scanning, and a signature code-transformation agent that upgrades old Java applications with one command. For teams already inside AWS, it also answers account and architecture questions from live console context.
A perpetual free tier allows 50 agentic interactions and 1,000 transformed lines per month; Pro costs $19 per user per month with 4,000 transformed lines included and $0.003 per line beyond. Against Copilot’s $10, Q costs more but ships the modernisation agent and deeper AWS integration – the reasons to switch are enterprise, not price.
