What do I need to know to upload a theme or extension on the Magento Marketplace?
Magento currently invests in ensuring high extension quality by strictly adhering to the following checks for every new extension submission request:
Business review: Ensures that each extension solves a business problem and delivers rich and unique functionality.
Tech review: Detects the presence of viruses, malware, and any indications of plagiarism. Ensures that the package meets Composer packaging and format requirements along with all coding standards.
Marketing review: Verifies that all documentation and appropriate information is provided for each extension.
