Master Algorithms. Actually.
Step-by-step interactive visualizations for sorting, searching, data structures, and dynamic programming — the way your textbook never could.
How It Works
Master algorithms in 3 simple steps
Step 1
Choose your algorithm
Pick from 25 algorithms across 4 categories — sorting, searching, graphs, and more. Find exactly what you need without endless scrolling.
Features
Everything you need to actually learn
Not just diagrams. Not just pseudocode. Real animations tied to real code, step by step.
Visual step-by-step execution
Watch every comparison, swap, and traversal in real time as it happens.
Code alongside the visual
See the exact lines executing as the animation plays — no gap between theory and code.
4 complete algorithm categories
Sorting, searching, data structures, and dynamic programming — all in one place.
Multiple language implementations
JavaScript, Python, Java, C++ — pick what you know and learn in context.
Categories
Four pillars of computer science
Every algorithm you need for interviews and beyond, visualized and explained.
Sorting
Bubble, Merge, Quick, Heap, and more
Searching
Binary Search, BFS, DFS, A*
Data Structures
Arrays, Trees, Graphs, Heaps
Dynamic Programming
Fibonacci, Knapsack, LCS
The Problem
Learning algorithms shouldn't feel like guesswork
“Reading pseudocode doesn't show you why it works”
Walls of code and abstract notation leave you guessing at the intuition behind every step.
“Static diagrams freeze the moment — they can't show state changes”
A single snapshot can't capture how data transforms at each iteration or recursive call.
“Misunderstanding one algorithm costs hours of interview prep”
One shaky concept compounds — you reach a mock interview unable to reason through the solution.
“Switching between a textbook and a debugger breaks your focus”
Context-switching between theory and a bare REPL makes it hard to connect the two.
There's a better way to build the intuition that sticks.
