Algocraft
Algocraft helps students, interview candidates, and developers learn data structures and algorithms through step-by-step visualizations, live inputs, pseudo-code, and guided state changes.
DSA & Algorithms
Step-by-step animations of 40+ algorithms. Watch DP tables fill, graphs traverse, trees rotate, and sorting partitions form — live.
Start Visualizing →System Design
Explore how WhatsApp, Netflix, YouTube, Instagram, and AI agent systems are actually built — with interactive flows, trade-offs, and tech stack breakdowns.
Explore Designs →Git Commands
Watch a live commit graph react to every command — branches fork in color, merges gain real parent edges, rebase visibly rewrites hashes. Step through guided scenarios or run your own in Sandbox mode.
Explore Commands →Quiz
All 13 theory topics, grounded in each topic's own diagrams and worked examples — not generic recall. A quick Section-wise Quiz or a Full Length Quiz per topic (every section touched), all timed at 1 minute per question.
Start the Quiz →See DP tables, graph visits, tree operations, sorting partitions, backtracking choices, and string matching decisions as they happen.
Use it to learn first principles, revise common patterns, explain concepts, or demo algorithms clearly.
Change examples, step through execution, and connect each visual update to the algorithm rule behind it.
