You were never meantto see it run.( until now )
Not another bar-chart toy. A real engine you can read.
Three things make AlgoPlus different — and they all point the same direction: understanding, not just animation.
Watch the code light up as it runs
Every comparison, swap, and pointer move highlights the exact line of source executing — across sorting, searching, graphs, trees, and more. Read the algorithm and see it move, together.
Runs in your browser, instantly
Every step is computed client-side — no server round-trips, no cold starts. Play, scrub, and change the input with zero latency, and it scales to any number of learners at once.
Far beyond sorting bars
Data structures, problem-solving patterns, and system design — each shown as the structure it really is: heaps as trees, recursion as call trees, caches as eviction lists.
See algorithms think.
This is the part nobody else does. As each step runs, the exact line of code lights up beside the bars it's touching — comparisons, swaps, and all. Read it and watch it, in lockstep.
One engine. Every branch of CS.
Eight modules, 193 interactive topics — each riding the same timeline, code-sync, and AI tutor. Pick a branch and dive in. Browse everything →
Every step, explained.
Step-aware narration with deep algorithmic intuition, time complexity, and analogical explanations. Pluggable interface ready for Claude, GPT, and Gemini.
One engine, every domain.
Anything that evolves through steps becomes a snapshot stream that rides one shared timeline — computed in the browser, rendered as fast 2D, narrated by the tutor. Add a domain, reuse everything.
