I built a complete cloud IDE that runs entirely in your browser. Here's why I think it matters.
My name is Augustine. I'm a developer and I've spent the last several months building Cloudpen, a professional cloud development environment that works in any browser on any device, including your phone.
I want to share what it is, why I built it, and what makes it different from the other browser IDEs you've probably already tried.
The problem I was solving
The developer tooling stack has become expensive and fragmented. If you're using VS Code, GitHub Pro, Vercel, and GitHub Copilot, you're paying $50 to $80 a month across four separate tools with four separate logins. For developers in emerging markets, that's not a small number. And none of those tools work well on a phone, which for a lot of developers globally is their primary device.
What Cloudpen actually is
Cloudpen brings everything into one browser tab. You get a professional code editor (the same engine behind VS Code), a real PTY terminal over WebSocket, one-click deployment to a live URL with automatic SSL, a built-in AI assistant called Quill, GitHub sync with webhook auto-redeploy, and real-time team collaboration with role-based permissions.
Everything. One tab. $12 a month. No installation.
What makes it genuinely different
Three things that I haven't seen any other cloud IDE do together:
First, it works fully on a smartphone. Not a stripped-down mobile view. The actual editor, terminal, file tree, search, and deployment all work on your phone. I built this deliberately because a lot of the developers I care most about are mobile-first.
Second, one-click deployment is a first-class feature, not an afterthought. You write code and you get a live URL with SSL in seconds. No separate Vercel account. No config files. Just click Deploy.
Third, the price. At $12 a month Pro replaces tools that together cost $50 to $80. For students it's $6 a month, every renewal, not just the first month.
Where it is today
Cloudpen is live at cloudpen.dev. We have active users, the platform has been tested by developers locally and internationally, and it's working. I'm building in public and I'm genuinely interested in feedback from other developers.
If you've been frustrated by how expensive and fragmented the standard dev setup has become, I'd love for you to try it.
