LeetCode review
A focused exercise platform for interview preparation, coding practice, and progress tracking.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
LeetCode is an online coding practice platform for developers and interview candidates. Its core experience centers on a curated problem library, an in-browser editor with language templates, custom test cases, backend judging, solutions, discussions, contests, study plans, and progress tracking. It supports C++, Java, Python, C, C#, JavaScript, Ruby, Swift, Go, Scala, Kotlin, Rust, MySQL, and Bash, with access through the web and official iOS and Android apps. The platform is best suited to developers preparing for coding interviews or building consistency through exercise-based practice.
The free plan provides access to the core practice experience, while Premium Monthly and Premium Yearly add premium content, company-specific interview questions, interview simulations, autocomplete, a debugger, and priority judging. Premium also adds exclusive content, debugging tools, cloud storage, and other interview-focused capabilities. This structure makes LeetCode easy to approach for occasional practice, while the paid tiers are aimed at candidates who want more targeted preparation and additional coding assistance.
Its standout strength is the combination of problem solving, execution, feedback, and community resources in one workflow. Users can run code against custom cases, submit it for judging against backend test cases, review solutions, join discussions, enter contests, and use an AI coding agent for brainstorming, optimization, test generation, and debugging. The trade-off is a focus on exercises rather than project-based or instructor-led learning, so it is less suitable for someone seeking a complete beginner curriculum or a primarily visual course experience. Choose LeetCode for repeated coding practice and interview preparation; consider a more structured learning format when guided instruction is the priority.
