Hacktoberfest Hack Day Madrid
About
Hacktoberfest Madrid 2026 es un Hack Day presencial y gratuito para gente con ganas de construir cosas con open source y AI.
Durante la tarde vamos a trabajar en equipos, probar herramientas y modelos open-weight, armar proyectos y cerrar con demos de lo que salió. No hace falta venir con equipo ni con una idea cerrada: la idea es conocer gente, experimentar y construir algo juntos.
Si te interesa open source, AI, programar, aprender algo nuevo o simplemente pasar una tarde rodeado de gente tech, sos más que bienvenido.
