AWS is introducing the free AI tool CodeWhisperer. The tool allows developers to write faster and safer code based on AI-based suggestions, making it an alternative to GitHub Copilot.

The AI-based code tool gives developers various suggestions during the coding process. This allows them to write their code faster and more securely and focus on their work more efficiently. They then do not have to interrupt their workflows and leave their code editor to look for information elsewhere.


According to AWS, the tool is suitable for creating code for routines and time-consuming tasks or collaborating with unknown APIs or SDKs. Amazon CodeWhisperer also correctly and effectively uses existing AWS APIs and other general coding scenarios such as read/write of files, processing images and writing unit tests.

AWS has also taken the necessary security measures so that the tool works responsibly. Code proposals that may be biased or unfair are automatically filtered out.

In addition, the tool automatically filters or flags code suggestions that may resemble specific open-source training data. Furthermore, the tool applies security scanning to find and recommend code suggestions for hard-to-find vulnerabilities.

Other features

Amazon CodeWhisperer, which resembles GitHub’s Copilot in its functionality, is available in a free and a “professional” version. The latter version also has administrative features such as SSO and IAM Identity Center.

Furthermore, the tool works with the code languages Python, Java, JavaScript, TypeScript, C#, Go, Rust, PHP, Ruby, Kotlin, C, C++, Shell scripting, SQL and Scala.
