I'm an OpenCart module developer (and more), and this is where I store the source code for the modules and extensions I create for this CMS. While most modules are commercial and their code is encrypted, there are also open-source ones available. The commercial repositories serve as showcases where you can read detailed descriptions, track updates, and changes.
Follow this profile and the repositories you're interested in to stay up to date with new versions, suggest improvements, or report bugs.
All modules and extensions are available on the OpenCart Marketplace.
