Preparing for technical interviews can feel overwhelming. Between hundreds of problem lists, inconsistent tags, and endless scrolling, it is often hard to know where to start or what to practice next.
While going through this myself recently, I realized that what I really needed was not another huge problem bank, but a simple tool to explore questions more efficiently.
So I built LeetIndex.
🎯 What is LeetIndex?
LeetIndex is a lightweight, fast tool that helps you browse and explore coding problems more easily.
It offers:
Search across thousands of coding questions
Filters for companies (a wide range, not just FAANG)
Difficulty filters (Easy, Medium, Hard)
Topic tags and problem patterns
Quality scores that highlight commonly recommended problems
A clean, distraction free interface
No ads. No login. Just a smoother way to discover useful practice material.
💡 Why I Built It
I found myself constantly jumping between problem lists, GitHub repos, and spreadsheets to identify good practice questions.
Most tools felt either too heavy or too limited.
LeetIndex is not meant to replace structured preparation or guarantee interview results. It simply makes it easier to find the kinds of problems that are widely recommended when studying.
Think of it as a helper that reduces friction in your practice routine.
⚡ How It Works
LeetIndex organizes problems by:
Company tags (many companies supported)
Difficulty
I am also working on adding topic categories like dynamic programming, graphs, trees, prefix sums, intervals, and more
Each problem includes helpful metadata and a general quality score based on community usefulness.
The interface is intentionally minimal and fast so you can focus on practicing instead of navigating a cluttered UI.
🧪 Try It Out
You can explore it here:

It is completely free and takes only a few seconds to get started.
🙌 Final Thoughts
Interview prep tools should not overpromise. They should support your work and make the process smoother.
LeetIndex was built with that goal in mind, and I hope it helps anyone looking for a cleaner, more organized way to practice coding problems.
If you try it out, feel free to share feedback or ideas.
