# Hacktoberfest 2026

> 300+ in-person Fests plus a global online event, all about building with open-source AI. Join a Fest near you this October.

Hacktoberfest is an annual event stewarded by Major League Hacking (MLH) and DEV, with presenting partner DigitalOcean. It began in 2014 as a pull-request challenge run by DigitalOcean. In 2026 it becomes an event you take part in: 300+ community-hosted, one-day “Fests”, plus an online event open to everyone. The focus is hands-on building with open models, open source agents, and open tooling.

- [Complete event context](./llms-full.txt): The full public copy of the site as one plain-text file.

## Taking part

- Fest applications are now closed. Fests run through October in two formats: Hack Days, funded mini-hackathons where people build projects, and Meet Ups, lighter gatherings that MLH does not fund. Anyone who still wants to host can apply to host an MLH Hack Day (https://www.mlh.com/hack-days), a separate MLH program of free, in-person mini hackathons held on a date the host picks.
- Sponsorship has its own page at /sponsor/: the confirmed sponsor wall, the campaign footprint, and how to start sponsor setup or request partnership info.
- Confirmed Fests are published at /fests/, searchable by name, city, or country, with a map and a
