LibreJam

LibreJam is a bi-monthly (formerly monthly) game jam that focuses on entirely libre entries. It was established by Katherine Peeters and is also hosted using entirely libre services. Piga Software has used it as an excuse to prototype ideas on its various engine drafts, somewhat similarly to how holiday releases spurred on development of the Gambas Arcade Engine in the early 2010s.
