In their own words
Eolymp
Eolymp provides tools for creating and hosting programming competitions and learning activities, from small practice rounds to official contests the maker says can involve thousands of participants. Organizers can run synchronized online contests or virtual contests with individual timers, then allow upsolving. Contests support IOI scoring with partial credit and ICPC scoring with time penalties. Problem-authoring tools cover statements, tests, checkers, solutions, validators, interactors and generators; problems can also be imported from Basecamp or Polygon. Courses bring together modules, learning materials, assignments and grades. The API uses HTTPS and JSON, offers API-key or OAuth 2.0 authentication, and has SDKs for Python, Go, PHP and JavaScript. Each space can connect supported AI clients through an MCP server, subject to the signed-in user's permissions. Free Services cost nothing and include problem materials, competition access and automatic solution testing. A new space can be tried free for 30 days with five seats and no payment details to start.
