What resource provides non-commercial products from Salesforce?

Salesforce.org serves as a specific resource that offers non-commercial products aimed primarily at educational institutions, nonprofits, and philanthropic organizations. This initiative is designed to promote social good by providing these sectors access to Salesforce's powerful tools and technologies without the typical commercial constraints.

Salesforce.org includes resources such as grants, discounted licenses, and specialized solutions tailored to the unique needs of nonprofits and educational entities. This focus on social impact differentiates it from other resources that typically cater to for-profit businesses or commercial interests.

In contrast, Salesforce Trails is primarily an educational platform focused on providing training and learning paths; AppExchange is a marketplace for third-party applications, which mainly offers commercial solutions, and Salesforce Support is focused on helping customers with technical issues rather than offering products. Therefore, Salesforce.org stands out as the correct answer by being the dedicated platform providing non-commercial resources.
