Offline

Warning

CS50 IDE is no longer supported.

Normally, CS50 IDE requires a constant connection to the internet. This may not fit users with slow or unstable internet connections, or those who want to continue using the IDE offline for any number of reasons. The following instructions walk you through how to download and install the offline version of CS50 IDE. Please note that the new offline IDE may be quite a large download (several GB).

Installing

CS50 IDE Offline is a containerized app. In order to run it, you need to install a tool called Docker. See Get Docker for instructions on how to install Docker for your operating system!

`ide50`

Instead of using Docker commands to manage your IDE, you may use ide50, a command-line script that facilitates using CS50 IDE Offline. To install ide50, open up your command prompt or terminal app and run the following command:

pip3 install ide50

Run ide50 -h to verify that the installation was successful and see usage information.

You may need to install Python 3 and pip first, if not already installed on your system.

Starting Your IDE

Once you have installed Docker and ide50, you can start your IDE by opening up your command prompt or terminal app, and running the following command:

ide50 start

Stopping your IDE

To stop your IDE, open up your command prompt or terminal app and run the following command:

ide50 stop

Updating Your IDE

Unlike the online version of CS50 IDE, the offline version needs to be manually updated. To update your IDE, open up your command prompt or terminal app and run:

ide50 update

then follow the instructions for Stopping Your IDE and Starting Your IDE to start an IDE based on the updated image.

Checking the Status of Your IDE

To check whether or not your IDE is running, open up your command prompt or terminal app and run:

ide50 status
