Honcathon is a new virtual event celebrated in November, designed to fill the gap between October's Hacktoberfest and December's Advent of Code, by focusing on web development with a playful theme centered around geese migration. The event features the HONC stack—comprising Hono as a web framework, Drizzle ORM, Neon database, and Cloudflare Workers—to accelerate web project development, while Fiberplane aids in debugging and testing APIs. Participants can choose from four application-building categories, with a chance to win a €500 Amazon voucher. The event is designed to be accessible, allowing projects to be completed in a half-day to a day, and submissions are due by December 15th.
