Gatsby has launched a new Partner Program aimed at supporting agencies and development shops that use Gatsby to build fast websites and web apps. This initiative promises to enhance visibility for partners by featuring their work in the Gatsby Site Showcase, and it aims to offer additional benefits such as developer training, joint case studies, and exclusive partner merchandise in the future. Agencies can express interest by submitting their Gatsby-built websites and filling out a form to receive updates on program developments. The program is designed to foster a collaborative community and provide resources that help partners grow alongside Gatsby's expanding open-source ecosystem.
