Yandex Contest

What Yandex Contest is

Yandex Contest is a web platform for programming competitions, practice and lessons, with automatic checking of submitted solutions. Schools, universities and competition organizers are among the audiences named by its maker. Organizers can build problems themselves or choose ready-made sets, then configure contest rules, deadlines and ratings and invite participants. Contests can be individual or team-based, and may be open or restricted. A testing server checks submissions and presents results according to the rules set for each contest.

The platform lists more than 20 programming languages, with compiler settings for supported languages. Its demo includes checker-based, interactive, run-twice, test, text-answer and matching problem types. Organizers can use a public API to register participants, manage groups, retrieve contest and problem details, submit or rejudge solutions, and export leaderboard data. API calls use OAuth tokens and permissions for participant submissions or administrator contest management. Users sign in with Yandex ID or credentials provided by organizers. The free organizer plan covers up to 10,000 participants; the maker says its computing capacity supports more than 10,000 simultaneously, and advises contacting Yandex about competitions expected to exceed 10,000.
