- 14 categories: sorting, graphs, pathfinding, trees, DP, math, physics, strings, geometry, backtracking, compression, fractals, curves & more - Step-by-step playback with play, pause, step, scrub, 0.25x–16x speed - Live simulations and interactive canvas modes - Configurable inputs and color legends - 4 themes (System, Light, Dark, AMOLED), 10 accent colors - Pinch-to-zoom on canvas - Fully offline — no ads, no tracking - Open source (GPLv3)
Visualize algorithms — sorting, graphs, fractals & more. Free, offline & no ads.
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 Sorting — Quick Sort, Merge Sort, Heap Sort, Tim Sort, Radix Sort, and more Graph Traversal — BFS, DFS, Dijkstra's, A*, Bellman-Ford, Kruskal's, Prim's, Floyd-Warshall Pathfinding — A* on grids, maze generation and solving 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. ## Source Code https://github.com/vivekg7/algo_canvas ## License Algo Canvas is free and open-source software licensed under the GNU General Public License v3.0 (GPLv3).
