Frequently Asked
Which concepts are free?
One concept per category is always free: Event Loop (JavaScript), Singleton (Design Patterns), Load Balancer (System Design), Netflix Architecture (Architecture), GIL (Python), and useEffect (React). No account needed.
How does country-based pricing work?
We use Purchasing Power Parity (PPP) — the same plan is priced differently depending on your country so it's fair wherever you are. We detect your location automatically and show the local price.
What plans are available?
We offer 3-Month, 6-Month, and 1-Year plans. All plans include full access to every visualizer. Longer plans come with a better per-month rate.
Can I cancel anytime?
Yes — no lock-in. Your access runs until the end of the subscription period, then it expires. No auto-renewal without your consent.
Do you offer student discounts?
Yes — Mail us on hello@devvizs.com with your student email and we'll provide you with a discount.
Do all plans include the same content?
Yes — every plan gives you full access to all visualizers. The only difference is the duration and total price.
