Eventio is a developer event discovery and calendar platform that brings opportunities from across the technology community into one searchable place. It aggregates coding contests, hackathons, AI and data challenges, capture-the-flag competitions, conferences, workshops, and other developer deadlines from sources such as Codeforces, LeetCode, Kaggle, Devpost, MLH, ETHGlobal, and Google Developers.

The platform is designed to help developers spend less time searching scattered websites and more time building. Users can browse events in calendar, week, day, or list views, search by keyword, and apply quick filters such as online, free, and happening this week. Eventio covers competitive programming rounds, hackathon registrations and submission dates, AI challenges and workshops, and live security competitions.

For deadline management, Eventio offers calendar syncing, including Google Calendar connections for protected deadlines. Organizers can submit events, while developers can access documentation and explore the platform’s event coverage. Eventio presents itself as a focused command center for finding relevant opportunities and keeping important dates in view.
