🏆 Codeforces Competitive Programming Scraper

🚀 Pull Codeforces profiles, problems, contests, and leaderboards in seconds. Filter by handle, tag, contest type, or active status. No API key, no registration, no manual CSV wrangling.

The Codeforces Competitive Programming Scraper turns the official Codeforces public API into a clean, ready-to-use dataset. Codeforces is the world's most active competitive programming community, hosting weekly contests, a graded problem archive, and a global rating ladder used by recruiters, schools, and contest analysts. This actor exposes four modes that cover the catalog: user profiles, the full problem set, the complete contest list, and the rated users leaderboard.

Each mode emits a flat JSON record with stable identifiers, scored fields, and a direct URL back to Codeforces. Profile records carry rating and rank history, country, organization, and contribution score. Problem records carry difficulty rating, tags, solve count, and solve share. Contest records carry phase, duration, ICPC region, and ICPC season. Leaderboard records sort highest-rating-first so you can grab the top 100, 1,000, or 10,000 players in one run.

🎯 Target audience	💼 Primary use cases
Tech recruiters	Source talent and benchmark candidate skill levels
Coaches and trainers	Build curated problem sets for students by tag and rating
Contest organizers	Audit historical contests, archives, and ICPC entries
Researchers	Study competitive programming demographics and rating dynamics
Tooling and community sites	Sync Codeforces metadata into dashboards and leaderboards

📋 What the Codeforces Scraper does

• 👤 User mode. Pass a list of handles like tourist, Petr, Benq and get rating, max rating, rank, country, organization, registration date, and contribution score in one call.
• 🧩 Problem set mode. Pull the full archive of 8,000+ problems with rating, tags, contest id, solve count, and solve share.
• 🏟️ Contest list mode. Fetch every public contest with phase, type, duration, ICPC region, country, and start time. Optional gym contests via a toggle.
• 🏅 Rated users mode. Stream the global leaderboard sorted by rating, with optional active-only filter.
• 🏷️ Tag filtering. Restrict problems to specific topics like dp, graphs, binary search, math, greedy, or any official Codeforces tag.
• 📦 Bulk-friendly. User mode batches in chunks of 100 to respect the API and complete large jobs quickly.

Each record includes a mode discriminator (user, problem, contest, or ratedUser) so you can union the four shapes in one downstream table without losing track of which mode produced each row.

💡 Why it matters: Codeforces is the de facto benchmark for algorithmic skill. A structured pull of profiles, problems, and contest history powers recruiting funnels, coaching tools, research papers, and community dashboards without you maintaining custom API code.

📊 Data fields

Each record includes: avatar, city, contribution, country, firstName, friendOfCount, handle, lastName, lastOnlineTime, maxRank, maxRating, mode, organization, rank, rating, registrationTime, scrapedAt, titlePhoto, url. All 19 field names come from a real production run, so what you see here is what lands in your dataset.
