The MongoDB Atlas Hackathon was announced in December 2021, with a judging panel impressed by over 210 submissions. The submissions were categorized into five categories: Action Star, Automation Innovation, E-commerce Creation, Prime Time, and Choose Your Own Adventure. Winners were selected for their projects, including Souvik's Plant Monitor that used MongoDB Realm Functions and Triggers to track plant health, Alex's New Year Resolution Tracker with Weekly Automated Reports that utilized a MongoDB Atlas Serverless instance, and Patrick's Groovemade e-commerce app using MongoDB Atlas Search. Additionally, Kai's Temperature Sensing with Raspberry Pi into MongoDB project stood out in the Prime Time category, while Valeria's Asteria: Asteroids approaching Earth today project won the Choose Your Own Adventure category. The jury also picked ten runner-up projects for prizes worth $250 each.
