AWS Cloud9 provides a fully managed browser-based IDE that simplifies cloud-native development without requiring local environment configuration. I particularly like its integrated terminal, collaborative editing capabilities, built-in debugger, AWS CLI integration, and direct access to EC2-hosted development environments. The interface is intuitive and allows developers to begin coding almost immediately.

Performance has been reliable for infrastructure automation, Lambda development, Python applications, and cloud engineering tasks. Since the development environment runs inside AWS, developers can securely access AWS resources without extensive local configuration. Pricing is attractive because only the underlying EC2 resources are billed, making it economical for temporary development environments. Cloud9 also integrates well with Amazon Q and CodeWhisperer capabilities for AI-assisted coding workflows. Review collected by and hosted on G2.com.

Development environments depend on EC2 resources, so performance varies with the selected instance type. Compared to modern desktop IDEs such as VS Code, extension support and customization options are more limited. Since AWS is no longer onboarding new Cloud9 customers, long-term planning for alternative development environments should be considered. Review collected by and hosted on G2.com.
