Gatsby has launched a Swag Store to reward all contributors to its open-source projects, allowing them to receive free items like stickers, socks, and t-shirts as a token of appreciation. Contributors can claim their swag by logging into the store with their GitHub account and requesting a discount code, which is valid for one free item. The initiative is available to all contributors, including non-code contributors, who are encouraged to email Gatsby for their free swag. Shipping is globally free, although the company hints that this might not be sustainable indefinitely. The Swag Store's open-sourced code uses a Gatsby v2 site, Shopify for product management, Auth0 for authentication, and a custom API for discount codes. Gatsby invites its community to share photos of their swag on social media using the hashtag #buildwithgatsby and encourages feedback and ideas for new rewards.
