The Closure Compiler is a tool for making JavaScript download and run faster. It is a true compiler for JavaScript. Instead of compiling from a source language to machine code, it compiles from JavaScript to better JavaScript. It parses your JavaScript, analyzes it, removes dead code and rewrites and minimizes what's left. It also checks syntax, variable references, and types, and warns about common JavaScript pitfalls. | The IBM Swift Sandbox is an interactive website that lets you write Swift code and execute it in a server environment – on top of Linux! Each sandbox runs on IBM Cloud in a Docker container. Both the latest versions of Swift and its standard library are available for you to use. |

Built on the open Eclipse Che project, Red Hat CodeReady Workspaces provides developer workspaces, which include all the tools and the dependencies that are needed to code, build, test, run, and debug applications.

Cloud9 provides a development environment in the cloud. Cloud9 enables developers to get started with coding immediately with pre-setup environments called workspaces, collaborate with their peers with collaborative coding features, and build web apps with features like live preview and browser compatibility testing. It supports more than 40 languages, with class A support for PHP, Ruby, Python, JavaScript/Node.js, and Go.

Koding is a feature rich cloud-based development environment complete with free VMs, an attractive IDE & sudo level terminal access!

Get setup lightning fast in the cloud & code from anywhere, on any machine.

A development platform that enables you to not only edit your files from underlying services like FTP, GitHub, Dropbox and the like, but on top of that gives you the ability to collaborate, embed and share through Codeanywhere on any device.

Every project gets its own Box: an instantly available server-side development environment with full terminal access. With features such as forking, collaboration, importing from Git repos and more, Codio strives to remove as many barriers as possible to create a platform developers will enjoy using as their IDE of choice.

Eclipse Che makes Kubernetes development accessible for developer teams, providing one-click developer workspaces and eliminating local environment configuration for your entire team.

CodeSandbox allows developers to simply go to a URL in their browser to start building. This not only makes it easier to get started, it also makes it easier to share. You can just share your created work by sharing the URL, others can then (without downloading) further develop on these sandboxes.

StackBlitz is the browser-based IDE that eliminates time-consuming local configuration and lets you spend more time coding. Develop with Next.js, React, Angular, Vite, and more in a Node.js development environment entirely in your browser

Gitpod is an open source developer platform automating the provisioning of ready-to-code dev environments. Designed for applications running in the cloud, Gitpod frees engineering teams from the friction of manually setting-up loc
