The best coding practice websites in 2026 are LeetCode and NeetCode for interview patterns, HackerRank for company-style assessments, Codeforces and AtCoder for contests, Codewars and Exercism for language fluency, GeeksforGeeks for Indian placement prep, and freeCodeCamp for guided projects. Use one for interviews and one for fluency; more is noise.
Pick by goal: interviews, placements, contests or learning a language. Then do a little every day; streaks beat weekend marathons.
