In August 2019, Jason Lengstorf announced the winners of the Gatsby Theme Jam, a community celebration for developers creating themes using Gatsby. The event aimed to give back to the community by rewarding creators who published exemplary themes with exclusive swag and an all-expenses-paid trip to Gatsby Days. Participants were required to submit themes with demo sites, npm packages, and public repositories, while also meeting performance and accessibility standards. Out of 111 submissions, 52 passed the automated review, which involved audits from webpagetest.org and Lighthouse. The manual review highlighted coding best practices, accessibility, and creativity, with Vojtěch Holík's Simplecast theme and Allan Pooley's Prismic-powered legal pages theme being recognized as standout contributions. The initiative underscored the importance of high-quality examples in improving the theme ecosystem and expressed gratitude to all contributors, encouraging ongoing participation in theme development.
