What is CodeWhisperer?

CodeWhisperer is a cybersecurity tool. Amazon Q Developer is AWS's AI coding assistant for JetBrains, VS Code, Visual Studio, Eclipse and the command line, combining code generation, inline chat, agentic multistep tasks, security scanning and .NET and Java transformation with deep AWS expertise.

Amazon Q Developer is AWS's generative AI assistant for software development, delivered as plugins for JetBrains, VS Code, Visual Studio and Eclipse plus a command line tool. It generates code suggestions from snippets up to full functions, keeps an inline chat inside the editor, and translates natural language into bash in the terminal. Because it is an AWS product, it also answers questions about AWS services, reviews resources, analyzes bills and helps with architecture decisions. The agentic layer is what separates it from simpler autocomplete tools. The agent can read and write files, produce code diffs and run shell commands while working through multistep jobs such as writing unit tests, adding documentation, reviewing code and refactoring. AWS says these capabilities hold top scores on the SWE-Bench leaderboards. Separate transformation agents port .NET applications from Windows to Linux and upgrade Java versions, and the tool can be pointed at private repositories so recommendations reflect internal code. Security and cloud operations round out the product. It writes tests, optimizes code and scans for vulnerabilities, then proposes fixes for what it finds. In the AWS Management Console, Microsoft Teams and Slack it investigates operational incidents, diagnoses networking problems and advises on cost and architectural best practices. For data teams it supports natural language queries, pipeline coding, ML model design under SageMaker Studio and governed AI project work. The audience is professional developers and platform teams already inside the AWS ecosystem, from startups to enterprises modernizing legacy Java and .NET estates. Teams on other clouds or with no AWS footprint get less value from the cloud operations and transformation features, though the coding assistant stands on its own. The perpetual Free Tier includes 50 agentic chat interactions and transformation of up to 1,000 lines of code per month. AWS has announced that IDE plugin support ends on April 30, 2027 and directs users to Kiro for comparable capabilities, which matters for anyone planning a long rollout.

How do you use CodeWhisperer?

  1. 1Compare editions and the Free Tier
    Read the pricing page to see what the perpetual Free Tier covers, including the 50 monthly agentic chat interactions and 1,000 lines of code transformation.
  2. 2Install the plugin for your editor
    Pick the plugin for JetBrains, VS Code, Visual Studio or Eclipse, or install the command line tool for terminal completions and natural language to bash.
  3. 3Sign in with AWS Builder ID
    Authenticate through the IDE plugin so requests are tied to your AWS identity. This step happens inside the editor after the plugin is installed.
  4. 4Try inline chat and code suggestions
    Start with small requests: generate a function from a comment, ask the inline chat to explain existing code, or request a bash command in the terminal.
  5. 5Run an agentic task
    Hand the agent a multistep job such as writing unit tests or reviewing a change set, then follow the diffs and updates it produces and approve its work.
  6. 6Connect private repositories
    Link your internal code so suggestions and answers reflect company patterns before rolling the assistant out to a wider team.

Pros and cons

Pros

  • Works inside JetBrains, VS Code, Visual Studio and Eclipse, plus a command line tool for shell workAI
  • Agentic mode handles multistep jobs such as tests, docs, reviews and refactors with diffs and real time updatesAI
  • Security scanning proposes fixes and AWS claims stronger detection than leading benchmarkable tools on most languagesAI
  • Strong AWS knowledge for architecture, cost analysis and incident investigation in the console, Teams and SlackAI
  • Perpetual Free Tier with 50 agentic chat interactions and 1,000 lines of transformation per monthAI

Cons

  • AWS has announced that IDE plugin support ends on April 30, 2027, so long term plans carry migration riskAI
  • Much of the value assumes an AWS footprint; cloud operations and cost features are weak fits for other stacksAI
  • Pricing beyond the Free Tier is not stated on the homepage and needs a separate visit to the pricing pageAI
  • Private repository customization and transformation projects require setup and permissions work before value appearsAI
  • The rebrand from CodeWhisperer to Amazon Q Developer means older tutorials and docs no longer match the productAI
