Media Party Hackathon Barcelona, Powered by Cloudflare

Day three of Media Party Barcelona is a one-day build sprint at BIT Habitat, Barcelona's urban innovation centre in Poblenou. Around 100–120 selected developers, data scientists, journalists and designers form multidisciplinary teams and ship open-source prototypes across three tracks: workflow automation and agentic journalism, the post-search publisher economy, and information integrity and verification. Cloudflare is headline sponsor, supplying infrastructure and AI developer tooling plus its own challenge track with prizes tied to its developer ecosystem; small grant prizes are also awarded. Teams pitch and demo before the day closes. Useful for engineers who want a real applied-AI problem for a day, and for anyone working on trust and provenance on the web.
