Algo Canvas is a free, open-source algorithm visualizer that brings 90 algorithms to life through interactive animations. No internet required. No ads. No tracking. Just pure learning.
Step through sorting algorithms, watch graph traversals unfold, explore fractal geometry, simulate physics systems, and interact directly with the canvas — all on your device, completely offline.
WHAT'S INSIDE

Searching — Binary, Ternary, Jump, Linear Search
Trees — BST, AVL, Heap, Trie operations and traversals
Dynamic Programming — Knapsack, LCS, Edit Distance, Coin Change, LIS
Math & Signal — Fourier Transform, Sieve of Eratosthenes, Monte Carlo Pi
Physics & Simulation — Conway's Game of Life, Fluid Simulation, N-Body Gravity, Boids, Double Pendulum
String Algorithms — KMP, Rabin-Karp, Boyer-Moore, Manacher's
Computational Geometry — Convex Hull, Voronoi, Delaunay Triangulation
Backtracking — N-Queens, Sudoku Solver, Knight's Tour
Compression — Huffman Coding, Run-Length Encoding, LZW
Fractals — Mandelbrot, Julia Set, Sierpinski, Koch Snowflake, Dragon Curve
Space-Filling Curves — Hilbert, Peano, Z-Order
Interactive — Bezier curves, splines, pendulums, spring-mass systems
FEATURES
- Step-by-step playback with play, pause, step forward/backward, and scrub controls
- Live simulations for physics and cellular automata
- Interactive mode — drag control points, draw walls, manipulate objects on the canvas
- Speed control from 0.25x to 16x
- Configurable inputs — array sizes, grid dimensions, node counts, simulation parameters
- Color legends explaining what each color represents
- 4 themes — System, Light, Dark, AMOLED (pure black)
- 10 accent colors to personalize the look
- Search and filter to quickly find any algorithm
BUILT FOR LEARNING
Every design decision prioritizes clarity and educational value. Watch each step of an algorithm as it happens, understand the data structures involved, and build real intuition for how algorithms work.
NO INTERNET. NO ADS. NO TRACKING. ALWAYS FREE.
Algo Canvas collects zero data. There are no analytics, no telemetry, no crash reporting, no network calls. Everything runs entirely on your device.
