🔀Sorting Algorithm Visualizer

Sorting Algorithm Visualizer Online — Free & Interactive

Want to actually see how sorting algorithms work? Our free Sorting Algorithm Visualizer animates them step by step the moment you press play. As a clear, interactive sorting algorithm visualizer, it shows a set of bars being compared, swapped, and ordered in real time—so abstract pseudocode turns into something you can watch and understand.

Compare the classics side by side: bubble, selection, insertion, merge, quick, and heap sort, each with comparisons and swaps highlighted as they happen. Adjust the array size and animation speed, generate a fresh random array, and step through or play the whole run. Each algorithm comes with its best, average, and worst-case time complexity, so you see not just how it sorts but how efficiently. Whether you're a student, a teacher, or prepping for interviews, it makes algorithms click.

Simply pick an algorithm and press play. No sign-up, no downloads, no limits—just clear visual learning whenever you need it.
