15 Best LeetCode Alternatives 2023

If you are a developer, engineer, or data scientist, you are probably looking for a platform to help you improve your knowledge and skills in coding. LeetCode is a great platform to help you improve your skills and even practice for interviews.

LeetCode comes with more than 2,000 questions for you to practice. Also, you will get to prepare for interviews on LeetCode. Organizations can also go to the platform to look for talent.

You can also choose 14 popular languages on LeetCode, including Ruby, Python, JavaScript, MySQL, and C++. You can also utilize the playground feature to write, debug and test your projects.

Despite the great features available on LeetCode, some limitations will force you to look for alternatives. First, LeetCode has limited SQL questions, which may compel data analysts, senior data scientists, and BI engineers to find better tools.

LeetCode has limited video guides and step-by-step tutorials, making it challenging, especially if you get some answers wrong and don’t know the correct way to solve them.

The app isn’t very beginner-friendly, and doesn’t provide peer-to-peer mock interviews that can help you fine-tune your coding skills before the actual interview.

Not to worry though, you can find better alternatives out there.

In fact, we explore 15 of them in this post.

Best LeetCode Alternatives

1. Codewars
