AI Coding Assistants · Updated 2026
Quick Verdict
Choose Amazon CodeWhisperer if you are an individual developer or AWS-centric team seeking a free, productivity-boosting autocomplete. Choose Sourcegraph Cody if your team works with large, complex codebases and needs an AI assistant with deep, contextual understanding across your entire repository.
Amazon CodeWhisperer is a free, real-time code suggestion tool optimized for AWS services and individual developer productivity. Sourcegraph Cody is a paid assistant that indexes and understands your entire codebase to provide context-aware answers, explanations, and edits. Their core difference lies in scope: CodeWhisperer excels at inline generation, while Cody acts as a conversational expert on your specific code. This leads to different target audiences, with CodeWhisperer appealing to cost-conscious and AWS developers, and Cody to teams managing complex, multi-repository projects.
