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
Seamless Configuration

Level-set the student experience

Ensure learners have access to the same environment regardless of hardware or software configurations, to reduce or even eliminate frustration with technical issues. Hide or reveal complexity depending on students' learning stage. Teach and mentor in real-time, while learners follow along on their own devices.

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.


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.


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.
Integrated Course Materials

Course content controls the IDE

Course materials in Codio fully control the IDE. Each page can open and close the files you need to see for any individual page of content. You can also execute commands, open up browser pages and even highlight portions of code.

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
Sys Admin Free

Instantly install and assign anything

Configure the environment you need and distribute it instantly to students. Template your standard environments and pull them off the shelf when you need them. Because everything is running on our servers, you don’t need to worry about security.

Command-Line Access

Sudo-level privileges

Gain command-line access to the Ubuntu box. Codio's infrastructure supports anything that you choose to install and configure from the command line. Codio boxes have sudo level privileges so instructors and students can custom configure the environment.

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.
