CodeMash is a developer conference held annually in early January at the Kalahari resort in Sandusky, Ohio. The event spans multiple days, featuring workshops on Tuesday and Wednesday, followed by main sessions on Thursday and Friday. It also includes a free, hands-on program for children called KidzMash.

The conference offers a broad technical curriculum. Attendees can participate in deep-dive workshops, attend sessions on topics like modern web development, and explore a dedicated Maker Space for 3D printing and electronics. The community-driven event relies on sponsors to operate and features volunteer-led outreach programs.

Beyond the sessions, CodeMash emphasizes community and family. Many developers, like Microsoft MVP and speaker Bob Fornal, bring their families, with children attending KidzMash. The integrated resort setting allows for a mix of focused learning and informal networking, creating a unique environment for professional development.
