Cloud-based workflows have boosted team productivity but still need richer features and faster performance
AWS Cloud9 is powerful, but it can be improved in terms of performance, modern IDE features, limited updates, and dependency on AWS infrastructure, which sometimes slows productivity. Since it runs in the browser and depends on Amazon EC2 instances, performance can lag compared to local IDEs, especially for larger projects or lower specs instances. It also has limited modern IDE features compared to tools like Visual Studio Code, lacking a rich extension ecosystem, advanced UI customizations, and some modern developer productivity features. Improvements can include better performance optimization, a plugin ecosystem, faster startup times, and more frequent feature updates, as well as an improved collaboration experience. AWS Cloud9 is great for AWS native development but still lags behind modern IDEs in performance, flexibility, and the pace of innovation. In terms of improvements, richer extension ecosystems, faster startup, better performance for large projects, and triggering CI/CD pipeline integration would make the workflow much smoother. A stronger extension and customization capability would significantly enhance day-to-day work with AWS Cloud9. Offline or hybrid mode, including limited offline capabilities or local sync, would reduce the dependency on consistent internet connectivity. Better debugging and monitoring integration, with deeper integration into logging and monitoring tools like Amazon CloudWatch, would simplify troubleshooting without switching context. If AWS Cloud9 evolves with better performance, extensibility, and deeper DevOps integrations, it would become a much more complete modern development platform.

Unified workspace has enabled full-stack AI companion development and supports deep code navigation
The main area Replit should improve is end-to-end troubleshooting for multi-service applications. A project may have separate front end and back end workflows, several ports, development preview behavior, deployment behavior, environment variables, a database, and a third-party API. When something fails, the developer sometimes has to inspect each layer independently to determine where the problem began. A more unified diagnostic view showing the request path across services would make troubleshooting faster. It would also help to have clearer guidance when development and deployment behavior differ. A configuration that works in the workspace preview may still need adjustments for a published application. Replit agent could also make its verification boundaries more explicit. It should be clear whether it has confirmed that the code compiles, that a workflow started, and that an endpoint responded, or that the visible user experience was actually checked. Those are different levels of verification.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"One thing I like the most about AWS Cloud9 is how easy it is to access different things and to look for what you are searching for."
"Overall, AWS Cloud9 is a solid choice for working within the Amazon Web Services ecosystem, with its biggest strengths being zero setup, seamless AWS integration, scalability, and accessibility from anywhere, making development faster and more consistent."
"Some of the best features with AWS Cloud9 are that it is a cloud-based DE, so you do not have to have an IDE locally or set up the IDE every time when using different computers."
"Replit's strongest value in my experience is its combination of code, workflow, preview, deployment, configuration, and AI-assisted development in one environment."
 

Cons

"AWS Cloud9 is great for AWS native development but still lags behind modern IDEs in performance, flexibility, and the pace of innovation."
"Regarding the learning curve of AWS Cloud9, I would say for an average person, it will take at least three weeks to a month of consistently using it to finally get out of that learning curve."
"AWS Cloud9 is being discontinued, so preventing its discontinuation would address the main pain point."
"Replit is actually expensive; I will not lie, it is actually expensive, but because of the capabilities it was actually giving me, I have just been able to pay the fee which I am being given."
