Sololearn Backup is a Chrome extension developed by Arnav that allows users to easily export and download their codes from Sololearn as a zip file. With no extra setup required, users can simply visit someone's Sololearn profile and navigate to their code bits section. Here, a new button named "Export Codes" will appear (users may need to reload the page once if the button doesn't appear initially). By clicking this button, users can export their codes, which will be downloaded as a zip file.

Each code is exported as a folder containing a metadata.json file and the corresponding source code files. Sololearn Backup also supports exporting private codes when the user is logged in. Additionally, it can be used to export other person's public codes.

Sololearn Backup is a free Chrome extension, making it a convenient tool for Sololearn users who want to back up their codes or download codes from other users. It provides a simple and efficient way to export codes, ensuring that users can easily access and store their valuable programming work.
