Eolymp vs HackerRank

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.

HackerRank helps companies attract, hire, and upskill developers, while also supporting a developer community. Its Screen product offers take-home technical assessments for evaluating applicants in the hiring funnel. Teams can use role-based Certified Assessments or generate a test from an uploaded job description. Screen includes a suspicious-activity model, a proctor, and identity and multiple-face monitoring. HackerRank APIs can automate test administration, interviews, user and team management, candidate data, and question retrieval. Integration categories include ATS, scheduling, talent intelligence, SSO, and productivity tools. The HackerRank for Work platform supports Chrome, Edge, and Firefox on Windows and macOS, plus Safari on macOS; a desktop app is available for Windows and macOS, including Apple Silicon and Intel Macs. HackerRank says its AWS platform complies with ISO 27001 and other listed security standards, and that redundant data centers provide 99.9% service availability. The Starter plan is $165 a month, billed $1,990 billed annually, with one user and 120 attempts per year; additional attempts cost $20. Pro is $375 a month, billed $4,490 billed annually.
