DrawToCode is an interactive platform designed to help students and developers understand data structures and algorithms through visualization and hands-on learning. Instead of only reading theory, users can see how algorithms work step by step.
The platform focuses on building strong conceptual understanding by combining visual learning, coding practice, and interactive tools in one place.
DrawToCode is built by Saurabh Patil, a Computer Science graduate passionate about simplifying complex programming concepts through visual learning.
The goal is to help learners go beyond memorization and truly understand how algorithms work internally.
Interactive visualization of data structures and algorithms
Step-by-step execution for better understanding
Support for multiple coding problems and patterns
Beginner-friendly interface for easy learning
Practice algorithms in a fun and engaging way using the shuffle game. It challenges users to think logically and improve problem-solving speed.
Track your learning journey with a personalized dashboard showing completed problems, progress, and improvement over time.
Combine visualization, coding, and logic building in one place for deeper understanding.
Students, competitive programmers, developers, and educators who want to learn algorithms in a more intuitive and visual way.
Browse 120+ curated DSA problems from arrays, trees, graphs, dynamic programming, and more — organized by difficulty and topic.
Paste your Java, C++, or Pseudocode solution directly into the DrawToCode page top left area after clicking top left button. The platform parses your code and breaks it into trackable instructions.
Watch your algorithm execute step by step on an interactive canvas visualization board with live data structure shapes — arrays, stacks, queues, trees, and pointers.
Replay the visualization, record it as a tutorial, or challenge yourself with the shuffle game to reinforce your understanding for interviews and exams.
DrawToCode supports visualization for a wide range of data structures and algorithm patterns commonly asked in coding interviews and university exams.

Yes, all features on DrawToCode are completely free. There are no paywalls or subscription plans required to access any visualization or problem.
DrawToCode supports all current and upcoming programming languages — including Java, C++, Python, JavaScript, and more. You can even track the execution of code written in pseudocode, making it the most flexible algorithm visualization tool available.
Yes. DrawToCode is designed to be beginner-friendly. The step-by-step execution and visual shapes make even complex algorithms easy to follow for first-time learners.
Absolutely. You can record your algorithm animations directly on the canvas and use them to build teaching content without any video editing software.
The Shuffle Game is a fun and interactive way to practice DSA. It presents you with shuffled algorithm steps and challenges you to arrange them in the correct order. Once you successfully arrange the steps, your progress is automatically reflected in your Progress Dashboard — keeping your learning journey tracked and up to date. This gamified approach helps reinforce your understanding of algorithm logic and improves problem-solving speed in a competitive and engaging way.
No installation is needed. DrawToCode runs entirely in the browser — just visit drawtocode.org and start visualizing immediately.
The Progress Dashboard is your personal learning tracker on DrawToCode. It shows all the problems you have completed, your overall progress across topics, and your improvement over time. It helps you stay consistent, identify weak areas, and plan your next steps in your DSA learning journey.
