Apache Superset at FOSDEM 2026

FOSDEM, Europe's largest open-source conference, offers a unique volunteer-driven format that gathers developers and enthusiasts in Brussels to engage in open-source collaboration and innovation without the commercial aspects typical of such events. The author attended FOSDEM with the goals of promoting Apache Superset, learning from other communities, and networking with potential collaborators, presenting on self-maintaining documentation in the Tool the Docs developer room. The talk highlighted a shift towards using AI to automate documentation processes, ensuring that documentation evolves directly from the codebase and stays current without manual upkeep. Real-world applications included automating country mapping visualizations, feature flags, API documentation, database connections, and more, reducing maintenance burdens and improving accuracy. The broader implications for open-source projects were discussed, emphasizing the role of comprehensive documentation in enhancing AI training. The event fostered community connections, with discussions at the Maintainer Unconference focusing on reducing contributor burdens and the future of open source. Alongside attending meetups and connecting with the data community, the author left FOSDEM inspired by the momentum and potential of open-source innovation.
