Online IDE | Edit, Compile, & Run Code

Get Learners Coding Immediately

Codio reduces computer lab costs by providing a cloud-based online coding IDE accessible from the classroom or from home on any device—even tablets and Chromebooks.

With our cloud-based IDE, there's nothing to install or download. All you need is a web browser and an internet connection to use our browser-based IDE.

Easy to Use

Maintaining a consistent IDE ensures students have access to the same development environment regardless of their hardware or software configurations, reducing the likelihood of compatibility issues.

With Codio's IDE, you can teach and instruct students in real time while they follow along on their own devices, level-set their experience, and reduce frustration with technical issues.

Unlimited Servers in the Cloud

Our in-browser IDE supports many programming languages such as Java, Python, C, C++, NodeJS, and more.

Codio's cloud-based IDE means learners can master these languages on any device, from computer lab desktops, to personal laptops, to tablets, to Chromebooks.

Deliver pre-configured environments at scale

Codio offers unparalleled scalability, making it an ideal choice for universities, Fortune 500 companies, school districts, or massive MOOCs. Regardless of your organization's size, Codio will seamlessly adapt to meet your needs.

No Installation Frustration

A "ready-to-go" learner-facing IDE

"We needed a student-facing IDE that was 'ready-to-go' and didn't require futzing or installation on the student's part but was sophisticated enough to handle our auto-grading demands without requiring extensive instructor time spent on dev-ops or configuration."

Armando FoxProfessor of Computer Science and Software Engineering at UC Berkeley

Specialty IDEs and Environments

Jupyter Notebooks, RStudio, VSCode, and more

Need a more specialized environment? Seamlessly assign Jupyter Notebooks with auto-grading tools like nbGrader, distribute RStudio assignments bundled with data sets, or give students practice on popular IDEs like VSCode—all within Codio.

Real-World Tools

Everything you'd expect in an industry-grade IDE

Integrated Debugger

The Codio IDE has a superb debugger that runs in the browser, with all the features you'd expect, including gutter-based breakpoint, automatic watching of local variables, manual variable watches, call stack, step over, step out, and more.

Virtual Desktop

Anyone can develop GUI-based applications in Codio. Whether Swing, JavaFX, tkinter, OpenGL, or anything else, they all run beautifully within your browser. This allows for a centralized management system to ensure all students can access the online IDEs.

Syntax Highlighting

Codio automatically selects the syntax highlighting rules based on the file extension.

Containerization

The Codio infrastructure delivers far more than a regular Virtual Machine infrastructure. Our intelligently managed containerization technology allows unlimited, fully fledged Ubuntu servers to be spun up in a couple of seconds. We charge the same if a student has one project or one hundred.

Code Complete

Autocomplete is supported in files in many languages. Simply start typing, and matches are automatically displayed.

Multiple Code Panels

The Codio IDE gives you complete control over your project layout. Configure your environment with multiple code panels, tabs, and layouts.

Automated Email

Email notifications are a great way to nudge students in the right direction to get their work done on time. Use templates to personalize emails to students at different progress points on projects, saving time and ensuring clear communication.

Custom Configurable Menus

Instructors can customize menus in Codio's IDE to remove options they don’t want students to have access to.

Themes

Customize the default theme for people viewing the content. You can enable both light and dark themes. Dyslexic users can also choose a specially-designed theme.

Code Beautification

The Code Beautifier feature automatically indents and manages spaces in your code to format it correctly.

Emmet Support

Codio offers default keyboard shortcuts and Emmet keyboard shortcuts, all of which can be customized.

Extensive Keyboard Shortcuts

Codio offers default keyboard shortcuts and Emmet keyboard shortcuts, all of which are customizable.

Code Playback and Review

One-click access to learner code

Instructors can easily access student projects to review, comment or provide feedback, and even playback the code as it was written.

Code Playback is built into Codio’s integrated development environment (IDE). This feature is available to all teachers and is extremely easy to use. With a few clicks, teachers can access all of the files that students produce in Codio.

Flexible and Accessible

Easily configure for any scenario

"What we love about Codio is the ease of configuration for any programming scenario and the fact that we can configure it entirely ourselves. Its integrated nature, flexibility, and the fact that all students need is a browser are fantastic."

Eitan Grinspun, PhDAssociate Professor of Computer Science at Columbia University

Integrated Collaboration Tools

Equipped for collaborative and pair programming

Pair Programming

Enable seamless student collaboration in pairs or small groups working within the same project concurrently. Codio enables using the driver and navigator model, with purposeful scaffolding and support for good pair programming habits. Students can seamlessly transfer driver control on-demand.

Collaborative coding tools

See where collaborators' cursors are and who is looking at a document with cursor presence. Codio ensures group members are not stepping on each other's toes while working together.

Integrated Chat and Video Conferencing

With Codio’s A/V and chat features, you no longer need multiple platforms to have a fully collaborative coding experience. Chat, audio or video call with project mates, instructors, or students within Codio.

In-Line Code Commenting

Instructors and even a TA can open a student project through the student's IDE, see what the student is currently doing, and leave a comment, starting a conversation entirely in Codio.
