AWS CodeWhisperer vs. GitHub Copilot

AWS CodeWhisperer and GitHub Copilot are two AI-powered coding assistance tools that are transforming how we write code. Both tools have been trained on billions of lines of code with the goal of enabling them to give accurate suggestions. They both support languages such as Python, JavaScript, TypeScript, Java, C#, Go, Ruby, and PHP. Additionally, both tools can integrate into popular code editors and GitHub repositories.

The difference between the two is in how they are used. While GitHub scans your repo to create context, AWS CodeWhispererer scans it to highlight vulnerable code. Additionally, unlike Copilot, AWS CodeWhispererer can be used for real-time collaboration and joint code reviews.

Lastly, GitHub Copilot is free to use, while AWS CodeWhispererer is only free for personal use. You require a subscription for commercial use.

Best Practices for using AWS CodeWhisperer
