Amazon Q Developer

Overview

Amazon Q Developer is an AI-powered coding assistant that writes, debugs, and refactors code directly inside popular integrated development environments. It helps developers accelerate tasks across the full software development lifecycle — from generating code suggestions and writing unit tests to scanning for vulnerabilities and upgrading legacy Java applications.

Unlike generic AI coding tools, Amazon Q Developer is deeply integrated with AWS. It can operate inside the AWS Management Console, Microsoft Teams, and Slack to optimize cloud costs, troubleshoot operational incidents, and recommend well-architected patterns. This makes it equally suited for day-to-day coding and for managing AWS infrastructure.

Key Benefits

• Generates real-time code suggestions from snippets to full functions based on comments and existing code.
• Reports the highest multiline code acceptance rate among competing assistants, as recently reported by BT Group.
• Scan code for vulnerabilities with detection performance that outperforms leading publicly benchmarkable tools across most popular programming languages.
• Achieved the highest scores on the SWE-Bench Leaderboard and Leaderboard Lite for agentic capabilities.
• Translate natural language to bash commands directly in the command line via CLI completions.
• Upgrade Java 8 applications to Java 17 using dedicated migration agents.

How It Works

You install the Amazon Q Developer plugin or extension in your IDE of choice — VS Code, JetBrains, Visual Studio, Eclipse, or the command line. As you write code, Amazon Q Developer produces inline suggestions; you accept them with a keystroke. You open the chat panel to ask questions about your codebase, generate unit tests, or request vulnerability scans. For complex multistep tasks, the agentic mode reads and writes files, generates diffs, and runs shell commands autonomously while incorporating your feedback in real time.

Use Cases

• Full-stack developers who want real-time code completions and inline chat without leaving their editor.
• DevOps engineers who need natural-language-to-bash translation and CLI autocompletions in the terminal.
• Cloud architects who use the AWS Management Console, Microsoft Teams, or Slack to investigate operational incidents and optimize resource costs.
• Enterprise teams migrating .NET applications from Windows to Linux or upgrading Java codebases across hundreds of production applications.
• Data engineers building analytics and ML pipelines who need natural-language query creation and code help for data workflows.
• Security-conscious teams who want automated vulnerability scanning with suggested remediations baked into the development workflow.

Why Choose This Product

Amazon Q Developer is best suited for developers and teams already operating in the AWS ecosystem who want an AI assistant that understands both their code and their cloud infrastructure. The perpetual Free Tier offers generous access, though agentic chat interactions are capped at 50 per month and code transformation is limited to 1,000 lines per month on the free plan.
