Maintainerati is a one-day Open Space unconference organized by the Maintainerati Core Team in collaboration with GitHub, taking place the day after GitHub Satellite at the Spreespeicher Conference Center in Berlin. It aims to provide a venue for open source software maintainers to gather, share challenges, discuss best practices, and build community support. This event is designed for maintainers who often feel unsupported and face challenges such as work overload and inadequate resources. By attending, participants can engage with others who share similar experiences and contribute to creating a more vibrant and inclusive open source community.
