90+ visualizers with step-by-step animations and your own inputs.
Interactive visualizations, a structured learning path, and the CS theory underneath, in one place.
90+ interactive visualizers brought to life. Pause, rewind, and step frame by frame. Inject your own data. Watch the exact line of code fire in real time.
A 17-phase path from star patterns and searching to advanced algorithms, with a visualizer, a problem or a short read at every step.
Three reading tracks: Operating Systems, Databases and Computer Networks. Each one is split into phases, and every article you finish is ticked off.
We don't show you slides. We put you in the driver's seat of the algorithm itself.
Pause, rewind, and step through any algorithm frame by frame. Build genuine intuition, not muscle memory.
Step through Bubble SortSee the exact line of code firing in real-time, synchronized perfectly with the on-canvas animation.
Open Binary SearchType your own values, pick your own start node, and see how the algorithm handles them.
Try Dijkstra'sLearning without structure is just browsing. The roadmap keeps you on track and lets you see how far you've come.
Understanding why algorithms work means knowing the systems beneath them. Three structured paths, each broken into phases.
From the kernel to the file system.
Learn how data is stored, queried, and protected.
Trace a packet from your laptop to a server across the world. Master IP addressing, TCP, DNS, HTTP, and the security layer that keeps it all safe..
From first-year CS to FAANG prep: every algorithm you'll meet, ready to run with your own input.
Follow the roadmap, visualize every algorithm, and build the CS theory underneath it all. Everything in one place, at your own pace.
