    What a partner gets next time

    The same as the 2026 partners got.

    A challenge built on your product

    We design the challenge with you, and your tools are available to every team from day one, not only to the ones that pick your challenge.

    Teams building with your tool

    You see live what teams build with your product, and the jury scores the meaningful use of the technology and of open source.

    A seat on the jury or as a mentor

    As Firecrawl did in 2026: Abimael Martell sat on the jury and mentored the teams on Build Day.

    Your winners in the public recap

    Your challenge's winners are announced with your name in the event recap and in this case study, with what they built and their repos.

    A report on what your challenge produced

    At the close you get how many teams used your tool, who won, what they built and the published repos.

    How the two days went

    Hacktoberfest has celebrated open source every October since 2014; in 2026 Major League Hacking and DEV asked people to build with open source AI and open-weight models, and Mexico City was one of its 500+ in-person Fests, as the organizers report.

    1. Day 1 · Tuesday, October 27

      Dev Townhouse

      Teams formed and the partners presented their challenges. Sergio Nouvel, co-founder and CEO of Get on Board, the largest tech job community in Latin America, spoke to the builders.

    2. Day 2 · Wednesday, October 28

      Sandbox Hub by Igeneris, Polanco

      Build Day and Demo Day. James Wong, Senior Vice President (Fintech) at Invest Hong Kong, joined us. At the close, 16 teams demoed for the jury.

    The jury

    • Valentín Martínez Director of Operations, Frutero Club
    • Andre Gejde Regional Growth Manager Mexico, Tangem
    • Abimael Martell Member of Technical Staff, Firecrawl; also a mentor on Build Day

    Five criteria: technical implementation, creativity and originality, practical application, meaningful use of technology and open source, and quality of the final demo.

    This year Hacktoberfest asked people to build with AI that anyone can download, review and adapt. In Mexico City, 16 teams used it to solve local problems, from finding a medicine the pharmacy ran out of to checking a supplier before paying them.
