You’ve recently started a job as an AV Technician, and during your downtime, you want to learn and code in Java. However, due to the secure nature of your role, you’re not allowed to download or install anything. You’ve tried Google Colab, but it only supports Python. Now, you’re looking for a 100% browser-based IDE that supports Java.
I’ve been exploring browser-based tools for side projects for a while now…
If you’re looking for a 100% browser-based IDE that supports Java, Replit is a solid choice. It’s clean, easy to use, and great if you’re jumping between different languages. You won’t need to install anything—just open your browser and start coding. I’ve used it a bunch for quick Java scripts and collaborative edits. The real-time sharing and multiplayer editing are quite handy, especially for pair programming.
It’s not going to replace IntelliJ IDEA if you’re working on enterprise-grade projects, but if you’re practicing or teaching Java—or just need a no-setup solution—it does the job pretty well.
As someone who often works with GitHub-based projects, I can add to what @shashank_watak said…
If you’re after a 100% browser-based IDE that supports Java and integrates tightly with your Git workflows, Gitpod might be more up your alley. It goes a step beyond Replit by letting you spin up dev environments from GitHub repos instantly. I’ve used it to work on full-stack Java projects without ever leaving my browser.
Plus, the Docker-based customization makes it a good fit for teams that want consistent environments. It’s definitely a bit more advanced, but once set up, it feels like a professional-grade dev setup—just browser-based.
Working in cloud-based ecosystems for the past few years, I’ve had to rely on tools that scale easily…”*
Building on @devan-skeem’s point, if you’re seeking a 100% browser-based IDE that supports Java and want deep cloud integration, AWS Cloud9 deserves a mention. It’s more than just an online editor—it’s a complete development environment backed by AWS. I’ve used it in multiple team settings where deployment and infrastructure were part of the workflow.
Cloud9 supports Java out of the box, and its integration with AWS services (like Lambda, EC2, etc.) is seamless. So if your Java development extends beyond coding into deployment or cloud-based automation, this could be your one-stop platform—all within your browser.
