A
Visualization built on algorithm state
Each visualization is built from the algorithm's own steps on a chosen example — the values, pointers and data structures at that moment — not from a recorded video.
CS VizLabs India Private Limited
Visual learning products for computer science.
We are an Indian technology company building interactive learning tools, designed to help learners understand hard computer science ideas by seeing them, reasoning through them and practising.
01 — What we build
See it. Reason about it. Write it.
We think the explanation of an algorithm, a step-by-step view of it running, and the place where you write it belong together — so a learner can move between them whenever they need to.
B
More than one way to solve it
Where a problem has more than one real approach, learners can see it solved from brute force to optimal, with the reason for each step.
C
Practice in the same place
The explanation, the visualization and an in-browser editor sit on the same page, so moving from understanding to writing code is one click.
02 — Our first product
Live
DSA Visually
An interactive platform for learning data structures and algorithms, designed to move learners beyond memorizing solutions. Every problem has the same five tabs. Start where you like, and open help when you are stuck.
Read
Problem
The task, the input and the expected output.
Reason
Strategy
Each approach with its key idea, complexity, intuition and the reason for every step.
Watch
Visualize
Step forward and back through the selected algorithm on a chosen example.
Write
Code
Write your own solution in C++, Java, Python or JavaScript, then run it and submit it against test cases.
Review
Submissions
Your earlier submissions and their results.
03 — Who it is for
Learners first. Colleges alongside what they already use.
Interview and placement preparation
For students getting ready for placements and coding interviews, and developers refreshing DSA for their next one — anyone who wants to understand why a solution works, not only that it does.
- A free Fundamentals track of 16 interactive lessons, with no sign-up required
- More than one approach to a problem, wherever a real alternative exists
- In-browser coding with a free account — write, run and submit
Visual DSA learning and coding practice for your students
A learning layer that sits beside an existing LMS, coding portal or placement workflow — not a replacement for it.
- Available today: the Fundamentals track, visual DSA problems, in-browser coding practice and per-student progress
- A 7-day student evaluation is available for selected college cohorts
- Tools for placement teams are in development
04 — Current stage
DSA Visually is live. We are an early-stage company, and we say so.
- The product is publicly available at dsavisually.com.
- Anyone can start for free: the Fundamentals track and a set of showcase problems are open without an account.
- A 7-day student evaluation is available for selected college cohorts.
- Premium access is not sold online yet.
- Institutional features — cohort-level progress, assessments and reports for placement teams — are in development and are not presented as available.
- We publish numbers only when we can stand behind them.
