Run Julia on CoCalc


CoCalc includes over 500 pre-installed Julia packages, and if something is missing you can easily install more packages.

Benefits of working with Julia online

  • You no longer have to install and maintain Julia. In particular when you're teaching a class, students just have to sign in to CoCalc to get started!
  • All your files are private, stored persistently, snapshotted and backed up.
  • You can invite collaborators to your project to simultaneously edit the same notebooks or code files.
  • Everything runs remotely, which means you do not have to worry about messing up your own computer.

Use Reactive Notebooks Built for Julia

You can use the Pluto.jl notebook server in any CoCalc project. Pluto is an open source lightweight and reactive notebook written in Julia.

Teach using Julia and Nbgrader

CoCalc's integrated course management system fully supports using nbgrader together with Julia Jupyter Notebooks.

We provide custom Julia templates for all the nbgrader cell types.

Tests run in the student's project, so malicious code won't impact anybody except the student.

Collaboratively Edit and Run Julia Code

CoCalc includes a realtime collaborative Julia code editor with syntax highlighting and code folding.

You can also run Julia code in a terminal side-by-side the .jl file you are editing.

In addition, you can chat with other CoCalc users about your code.
