About

AWS Cloud9 is a cloud-based integrated development environment (IDE) that lets you write, run, and debug your code with just a browser. It includes a code editor, debugger, and terminal. Cloud9 comes prepackaged with essential tools for popular programming languages, including JavaScript, Python, PHP, and more, so you don’t need to install files or configure your development machine to start new projects. Since your Cloud9 IDE is cloud-based, you can work on your projects from your office, home, or anywhere using an internet-connected machine. Cloud9 also provides a seamless experience for developing serverless applications enabling you to easily define resources, debug, and switch between local and remote execution of serverless applications. With Cloud9, you can quickly share your development environment with your team, enabling you to pair program and track each other's inputs in real time.

About

Replit is an AI-powered app development platform that helps users turn ideas into websites, mobile apps, designs, slides, animations, data visualizations, games, documents, and spreadsheets without needing to code manually. The platform features Agent 4, which can interpret prompts, plan requirements, write production-ready code, evolve projects, and publish apps. Replit includes Infinite Canvas for visually exploring and tweaking designs before applying them directly to an app. Parallel Agents let multiple tasks run at once, helping teams build authentication, databases, design, and other features faster. Built-in infrastructure includes authentication, database, hosting, monitoring, AI integrations, and connections to services such as OpenAI, Stripe, and Google Workspace. Built for individuals, teams, and enterprises, Replit helps users prototype, collaborate, launch, and scale software from one workspace.

Pros & Cons from Real Users

Pros

  • Compatible for most programming languages and allows export and import functionalities. Does not require to install.
  • No setup required. Easy to use interface. Supports multiple programming languages. Collaborate on code real-time. Integrated debugging tool.

Cons

  • Hangs for some moment when open in windows to share the code.
  • Lacks plugins and extensions. Takes time to execute larger projects.

Pros & Cons from Real Users

Pros

  • Replit is really compelling from a product manager’s perspective because it makes prototyping feel dramatically faster. I can describe an idea, explore a flow, test assumptions, and get something working without waiting for a full engineering cycle. I like that it is not just a mockup tool. Replit helps move from concept to actual software, which is huge for PMs who need to validate workflows, build internal tools, test MVPs, or show stakeholders something more concrete than a slide. The AI agent workflow is especially useful for early product discovery. It can help turn messy product thinking into a plan, build a first version, fix issues, and iterate quickly. That makes it easier to learn what is worth building before committing serious resources.
  • The editor is nice, though it still doesn't compare to local. The deployments feature is also great and easy to use.
  • Repl.it is web based. You can see what your web page looks like at the click of a button. Many other languages (Python, C++, etc.) simple UI. Dark or light mode. Very easy Github integration.

Cons

  • I would not treat Replit as a replacement for engineers, designers, or proper product judgment. AI-generated apps still need review, testing, security checks, usability work, and clear requirements.
  • I don't like what this company has turned into. It's buggy, slow, and expensive.
  • Not as much features as paid services, but you can have a $5/month fee for more features (unlimited data, better service, etc). No service that I found (I didn't need it tho).
