Founded in 2013, SeaGL aims to strengthen the free software movement through mentorship, collaboration, and community. The conference brings together technologists, students, contributors, and enthusiasts across many disciplines. SeaGL (Seattle GNU/Linux Conference) is a free—as in freedom and tea—grassroots technical summit dedicated to free/libre/open source software, hardware, and culture. The event is welcoming to newcomers, professionals, hobbyists, and anyone interested in FLOSS.
