Eolymp review
A broad contest and assessment platform with strong authoring and grading workflows.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Eolymp is an online judge and competition platform for programming practice, teaching, and contests. It is designed for schools, clubs, teachers, contest organizers, and programming competition participants. Participants submit programs for automatic compilation and grading against tests, while organizers can create problem archives, test suites, checkers, interactors, contests, courses, scoreboards, and member spaces. Supported programming languages include C++, Python, Java, Go, Pascal, Haskell, Lisp, Assembly, PHP, JavaScript, and C#.
Its strongest fit is assessment and contest administration rather than a narrow practice-only workflow. Problem authoring covers statements, tests, test suites, scoring, code templates, custom checkers, and interactive problems. Organizers can run ICPC and IOI formats, offer online or virtual participation, maintain scoreboards and participant records, and provide post-contest upsolve mode. Problem imports from Basecamp and Polygon can also support existing content libraries. Courses and educational spaces extend the platform beyond individual challenge solving.
According to the vendor's pricing page, Eolymp uses per-active-user pricing. The published offer includes a 30-day trial with five seats and no payment information required; ongoing use is paid rather than free. The platform is available through the web and an API. Choose Eolymp when you need one environment for automatic evaluation, custom challenge design, structured teaching, and formal contests. Teams seeking an ongoing free plan or a simpler practice tool should look elsewhere.
