Questions

Straight answers.

What exactly is free?

The whole Core CS track (operating systems, computer networks, database management systems and object-oriented programming, with every drill), plus the Foundations stage of System Design and of Low-Level Design, progress sync, bookmarks and both themes. It does not expire and does not need a card.

What does Pro add?

Everything beyond Foundations in System Design and Low-Level Design, every drill in those stages including the interview playbook, and whatever ships next: Blueprints and the lesson-scoped tutor are first.

Is there a lifetime plan or a sale?

No. One monthly price, one yearly price, no countdown banners. If you learn the track in a month, pay for a month.

Can I use it without an account?

Yes. Progress is kept on your device and merged into your account when you sign in, so nothing is lost by starting anonymously.

When does Pro checkout open?

With the next release. Create a free account now; your progress carries over and you will be told when Pro is live.
