I’ve been using Amazon Cloud9 for the past few months, mainly for Python and Node.js projects. Overall, it’s a solid cloud-based IDE that makes it really easy to work from anywhere without worrying about local setup. I especially like that it comes preconfigured with most popular tools and the integration with AWS services is seamless—it saves a lot of time when testing Lambda functions or other AWS resources.

The collaborative features are also pretty handy; being able to share your environment with teammates in real time has made remote debugging and pair programming much smoother.

On the downside, it can sometimes be a bit laggy compared to local IDEs, especially when handling large projects. Also, I noticed that some of the advanced configurations require AWS knowledge, which could be a barrier for beginners.

All in all, I’d recommend Cloud9 for developers who want a hassle-free, cloud-based development environment and are already using AWS. Review collected by and hosted on G2.com.

I like that AWS Cloud9 provides a fully-featured, browser-based IDE with seamless integration to AWS services, allowing me to code, run, and debug applications from anywhere without local setup. Review collected by and hosted on G2.com.

AWS Cloud9 can feel slower compared to local IDEs, and occasional latency or connectivity issues can interrupt the workflow, especially on large projects. Review collected by and hosted on G2.com.

AWS Cloud9 makes it incredibly easy to start coding immediately without having to set up or maintain a local environment. The built-in terminal, code editor, and debugger feel seamless, and the environment spins up quickly. I also love that projects run inside an EC2 instance, so the compute environment mirrors production. Real-time collaboration and the ability to share environments with teammates are big advantages. It integrates well with AWS services, and switching between IAM roles, Lambda functions, and the CLI inside the IDE saves a lot of time. It is really easy to use once it is set up, and i use it quite frequently Review collected by and hosted on G2.com.

The performance can be inconsistent, especially for larger workspaces, and the IDE can lag compared to local desktop IDEs. Pricing can also become confusing because you pay for the EC2 instance behind the environment. Some features feel dated, especially compared to VS Code extensions and UI responsiveness. Offline usage is impossible, and Cloud9 sometimes disconnects if the network quality drops. Integration with modern dev tools could be deeper. Intial set up is little hard mainly for people with less technical background. Review collected by and hosted on G2.com.

Cloud9's real-time collaboration features are best-in-class and often compared to a Google Docs for code.

Multi-user Editing, Shared Terminal Review collected by and hosted on G2.com.

It's Not "Free," It's "Free-ish": While the IDE software itself has no cost, you pay for the underlying EC2 instance and EBS storage 24/7.

The "Stop vs. Terminate" Confusion: This is a critical and often costly distinction.

Risk of Unexpected Bills: Forgetting to stop an environment running a powerful instance can lead to a surprisingly high monthly bill.
