In their own words
Yandex Contest
Yandex Contest is a free online platform for programming competitions, practice, and lessons with automatic solution checking. Organizers can create problems or select ready-made sets, then configure rules, deadlines, ratings, and invitations. Contests support individual or team participation and may be open or restricted. A testing server evaluates submissions according to contest rules. The platform lists more than 20 programming languages, with compiler settings for supported languages, and its demo includes checker-based, interactive, run-twice, test, text-answer, and matching problems. The public API uses OAuth permissions to register participants, manage groups, retrieve contest and problem details, submit or rejudge solutions, and export leaderboards. Users sign in with Yandex ID or organizer credentials. The organizer plan is free for up to 10,000 participants; organizers expecting more must contact Yandex. Full administrator-panel access requires a form.
