Learn System Design the Structured Way
The Ultimate Platform to Learn and Practice System Design Interviews
Practice System Design Questions and Get Feedback
"An ounce of practice is worth more than tons of preaching." — Mahatma Gandhi
Put this wisdom into action with our revolutionary platform. Don't just read about system design—practice it, refine it, and master it through actionable feedback.
Structured Learning
"Give a person a fish, and you feed them for a day; teach a person to fish, and you feed them for a lifetime." - Lao Tzu, Chinese philosopher
We don't just hand you solutions
we equip you with a conceptual toolkit to solve problems yourselves —-not just the ones we discuss.
Common Patterns, Unlimited Applications
No more reinventing the wheel for each unique challenge. Utilize our comprehensive design templates that act as a powerful foundation for solving a multitude of issues.
Real-World Code Examples
"Talk is cheap, show me the code." - Linus Torvalds, creator of Linux
Don't just read about it; experience it. Our platform offers not just blog-post theories but actual code snippets and examples that you can pull and run on your machine.
Dive into our 'Codelabs' for hands-on understanding
Forget convoluted setups; complex examples comes wrapped in a Docker container that you can easily clone and execute. This bridges the gap between theory and real-world application, making your learning journey as frictionless as possible.
Editorial Solutions with Code Implementation
Get the high level overview of the solution, then dive into the code to see how it's implemented. Whether you are a visual learner or a code learner, we've got you covered.
So yeah, it's pretty awesome. But don't just take our word for it. Try a practice problem!
Design LeetCode
Design a coding contest platform like LeetCode.
-
Users should be able to view problem descriptions, examples, constraints, and browse a list of problems.
-
Users should be able to solve coding questions by submitting their solution code and running it against built-in test cases to get results.
-
User can participate in coding contest. The contest is a timed event with a fixed duration of 2 hours consisting of four questions. The score is calculated based on the number of questions solved and the time taken to solve them. The results will be displayed in real time. The leaderboard will show the top 50 users with their usernames and scores.
Design URL Shortener
Design a URL Shortener service like bit.ly
-
Users should be able to input a long URL and receive a unique, shortened alias. The shortened URL should use a compact format with English letters and digits to save space and ensure uniqueness.
-
When users access a shortened URL, the service should redirect them seamlessly to the original URL with minimal delay.
-
The system should be able to track the number of times each shortened URL is accessed to provide insights into link usage.
Design Spotify Top K Songs
Design a system to find the top k heavy hitters in a stream of data. This could be
- the top k most played songs in a music streaming service like Spotify
- the top k most viewed videos on a video streaming service like YouTube
- the top k most bought items in an e-commerce service like Amazon
- the top k most frequent items in a social media service like Twitter
- the top k most accessed IP addresses on a network
Design Webhook
Design a webhook service that processes incoming requests and ensures efficient, secure handling of real-time events, such as payment notifications from services like Stripe or Shopify.
If you prefer the video format, here's a walkthrough of the problem:
-
Accept API calls to receive event notifications (e.g., payment processed or order shipped), execute corresponding operations, and persist original event data and operation results for tracking, auditing, and debugging.
-
The service must ensure events are processed even if system components fail, maintaining reliability for critical data.
Design a Collaborative Editing System like Google Docs
Design a collaborative editing system like Google Docs.
-
Single-user CRUD Operations in the Browser: Users can create, read, update, and delete documents directly in their web browser.
-
Users should be able to edit the same document concurrently and view each other's changes in real-time.
