What Eolymp is

Eolymp is a platform for creating and hosting programming competitions and learning activities. Organizers can schedule online contests or virtual contests with individual timers, then enable upsolving after a contest. Scoring options include IOI-style partial credit and ICPC-style time penalties. Problem-authoring tools cover statements, tests, checkers, solutions, validators, interactors, and generators; organizers can also import problems from Basecamp or Polygon. Course tools combine modules, learning materials, assignments, and grades. Eolymp says its hosted platform supports official competitions with thousands of participants as well as smaller practice rounds. Its API uses HTTPS and JSON, offers API-key or OAuth 2.0 authentication, and has SDKs for Python, Go, PHP, and JavaScript. Spaces can connect to supported AI clients through an MCP server, with permissions tied to the signed-in user. The maker also describes grading integration with Moodle or Canvas. A new space can be evaluated free for 30 days with five seats and no payment details required to begin.
