AWS Cloud9 Reviews & Product Details

What I like best about AWS Cloud9 is that it eliminates the hassle of local setup by providing a cloud-based IDE that’s ready to use, while also offering powerful collaboration features that let multiple developers work together in real time. It integrates seamlessly with AWS services, so you can easily build, run, and debug applications that interact with resources like Lambda, EC2, and S3 directly from the IDE. With support for multiple programming languages, a built-in Linux terminal, and the ability to access your environment from anywhere, Cloud9 makes development faster, more flexible, and highly collaborative—especially for teams working on AWS-based projects.

What I dislike about AWS Cloud9 is that, while it’s convenient as a cloud-based IDE, it can sometimes feel limited compared to a fully customized local development environment. The performance may lag depending on internet connectivity, and the interface can be slower when handling larger projects. Its collaboration features are useful, but they aren’t as smooth or feature-rich as dedicated tools like GitHub Codespaces or VS Code Live Share. Additionally, because Cloud9 is tightly integrated with AWS, it can feel restrictive if you want to work outside the AWS ecosystem, and the pricing model tied to EC2 instances may not be ideal for smaller teams or individual developers. Overall, it’s powerful for AWS-centric projects, but less flexible and occasionally less responsive than local or alternative cloud IDEs. Review collected by and hosted on G2.com.

AWS Cloud9 is easy to use because it provides a cloud-based development environment that can be accessed from anywhere. I like that it supports multiple programming languages, offers real-time collaboration, and integrates well with AWS services. It also removes the need for complex local setup, making coding, testing, and deployment faster and more convenient. Review collected by and hosted on G2.com.

One downside of AWS Cloud9 is that it depends heavily on a stable internet connection since it is cloud-based. Performance can sometimes feel slower compared to local IDEs, especially for large projects. It also has limited customization compared to desktop development environments, and some advanced features may require additional AWS configuration. Review collected by and hosted on G2.com.

What I like most about AWS Cloud9 is being able to write and run code directly in my browser without having to install anything on my laptop. It’s quick and easy to get started, and it connects smoothly with other AWS services, which saves me a lot of setup time. Performance is solid for everyday tasks, and because it runs on AWS infrastructure, it can handle scaling more easily than many local setups. I also appreciate that it works well with AI-based tools and other cloud services, which helps me write code faster and boosts my productivity. Review collected by and hosted on G2.com.

What I dislike about AWS Cloud9 is that its performance can be slow at times, especially when I’m working on larger projects or when my internet connection is limited. I also find that it lacks some of the advanced features and overall flexibility you get with modern IDEs like Visual Studio Code, which can make development feel a bit less efficient. On top of that, the built-in AI capabilities are fairly limited, so it doesn’t offer the same level of smart code suggestions or automation that many newer tools provide.

What I like most about AWS Cloud9 is how frictionless it makes development. You get a ready-to-use, browser-based IDE that’s already wired into AWS services, so there’s no local setup chaos or “works on my machine” drama. Real-time collaboration, built-in terminal access, and seamless IAM integration make it especially strong for cloud-native work. It feels less like configuring tools and more like actually building things—which is the whole point. Review collected by and hosted on G2.com.

What I dislike about AWS Cloud9 is that it can feel slow and resource-limited compared to a local IDE, especially on smaller EC2 instances. Startup times aren’t always instant, sessions can disconnect, and performance depends heavily on network quality. It’s also less customizable than full desktop editors, and costs can quietly add up since you’re paying for the underlying AWS resources even when you’re not actively coding.

I like that AWS Cloud9 provides a fully managed, cloud-based development environment that’s easy to set up and accessible from anywhere. It integrates seamlessly with other AWS services, supports real-time collaboration, and eliminates the need for local environment configuration, which makes development faster and more efficient. Review collected by and hosted on G2.com.

The main drawbacks are occasional performance lag, especially with larger projects, and limited customization compared to local IDEs. It also depends heavily on a stable internet connection, and managing underlying EC2 resources can add some complexity and cost if not monitored carefully. Review collected by and hosted on G2.com.

It provides a ready to use cloud based development environment with no local setup required. It runs directly inside AWS making it easy to access and manage AWS resources (EKS,EC2,S3 etc)

The built in editor and terminal simplify development, testing and troubleshooting

It also ensures consistent environment across teams and supports real time collaborations which improves productivity and reduces configuration issues Review collected by and hosted on G2.com.

It is more limited compared to local IDEs like vs code in terms of extensions, customization and performance because it runs on an underlying EC2 instance, startup times can be slow and the environment depends on instance availability. Review collected by and hosted on G2.com.

What I value most about Cloud9 is how seamlessly it lets me edit code and scripts that are already hosted within AWS. There are many times when I need to quickly update a script that isn’t in a git repository—and likely never will be—but is stored in an S3 bucket or linked to a Lambda function. In these scenarios, Cloud9 proves to be the perfect solution. It’s quick and easy to set up, and onboarding our other engineers was straightforward. Because of this, it has become one of the tools our team depends on most. Review collected by and hosted on G2.com.

AWS's decision to stop offering Cloud9 to new customers is quite puzzling. Nevertheless, at its core, Cloud9 remains a solid tool, even if it feels a bit barebones compared to other cloud-based IDEs. Review collected by and hosted on G2.com.

I find AWS Cloud9 easy to access for services like Lambda, EC2, S3, and others. As a backend Data Engineer, it helps a lot with quick interactions in AWS since I use Glue and Lambda regularly. It's integrated with Git, making collaboration smoother. Also, once logged in, the cloud environment is easy to use. I appreciate that AWS Cloud9 can be launched easily in just a few seconds, similar to downloading an app. Review collected by and hosted on G2.com.

I feel like AWS Cloud9 lacks full-fledged features of a desktop IDE. Review collected by and hosted on G2.com.

The browser-based terminal and IDE are fantastic for rapid environment creation for security testing and running tools without exposing my own computer. The direct IAM role integration is also beneficial for privilege escalation testing and policy auditing within a contained AWS environment. Review collected by and hosted on G2.com.

The lack of detailed network isolation makes it difficult to develop realistic segmented environments for red teaming. EC2 instances are exposed by default, and security groups have limited customization from the IDE, which is a pain. Additionally, there’s no built-in secrets scanning or IAM misconfiguration warnings. Review collected by and hosted on G2.com.

AWS Cloud9 is easy to use because it’s a browser-based IDE with no local setup. I like its tight integration with AWS services, built-in security using IAM, and real-time collaboration, which helps teams develop and test cloud applications faster. Review collected by and hosted on G2.com.

One drawback of AWS Cloud9 is that it depends heavily on a stable internet connection, and performance can feel slow at times for large projects. Also, it offers limited customization compared to local IDEs, and costs can increase if the underlying EC2 resources are not monitored properly. Review collected by and hosted on G2.com.
