LeetCode Alternatives
LeetCode is described as 'platform for learning and improving coding skills with the goal of being fully prepared for programming interviews. Choose problems to solve from categories such as System Design, Algorithms and Database, join code contests and engage in mock interviews' and is a Code Learning service in the development category. There are more than 25 alternatives to LeetCode, not only websites but also apps for a variety of platforms, including Windows, Self-Hosted solutions, Android and iPhone. The best alternative is Khan Academy, which is free. Other great sites and apps similar to LeetCode are Codecademy, exercism, Codewars and HackerRank.
LeetCode alternatives are mainly Code Learning Services but may also be Online Education Services or Code Editors. Filter by these if you want a narrower list of alternatives or looking for a specific functionality of LeetCode.- Free • Proprietary

Khan Academy vs LeetCode opinions
Is not the same. Does not have coding exercises and Computer courses are very limited
Codecademy is the easiest way to learn how to code. It's interactive, fun, and you can do it with your friends.
Download and solve practice problems in over 30 different languages. For code newbies and experienced programmers.
Achieve code mastery through challenge.
Codewars vs LeetCode opinions
dataculiI haven't used HackerRank yet, but Codewars is the most similar to LeetCode in terms of having a large library of problems you can solve in multiple different languages. It's a lot more focused on being crowd-sourced though so it has a larger library and the solutions aren't paywalled like in LeetCode
A fun social platform for hackers to solve interesting puzzles, build quick hacks, code game bots and collaborate to solve real-world challenges.
When learning to code, most people get stuck on the "bridge" between memorizing syntax and understanding the logic that makes it all work. We believe the most effective way to learn a programming language is to break the process into three phases:
Project Euler is a series of challenging mathematical/computer programming problems that will require more than just mathematical insights to solve.
Project Euler vs LeetCode opinions
dataculiA little more mathy. Instead of submitting a bit of code you actually submit the answer to a problem that should be solved through code. But it's free and unpaywalled so it's a cool little project. Currently around 760 problems
There is a mathematical focus and has good examples of why some problems need optimized algorithms. You get exposed to a lot of cool math concepts and are challenged to write in efficient time and space complexity.
Screeps is a massive multiplayer online real-time strategy game. Each player can create his or her own colony in a single persistent world shared by all the players. Such a colony can mine resources, build units, conquer territory.
Online game for Python and JavaScript coders to improve skills.
CodinGame is a challenge-based training platform for programmers where you can play with the hottest programming topics.
