Question 1

Is this really free?

Accepted Answer

Yes — every lab and every question, with no account, no trial timer, and no paid tier. The project is MIT licensed.

Question 2

Do I need a GPU, a cloud account, or anything installed?

Accepted Answer

None of the above. Both simulators run entirely in your browser. The cluster, nodes, scheduler and command output are simulated locally.

Question 3

Is this an official NVIDIA or AMD product?

Accepted Answer

No. Project Nest Egg is independent and unaffiliated. Content is not endorsed by any vendor and does not guarantee any certification outcome.

Question 4

How realistic is the terminal?

Accepted Answer

It is a real type-in shell with command history, tab completion, a small filesystem and man pages. The simulated cluster is stateful.

Question 5

What if I get stuck on a task?

Accepted Answer

Every task has a reveal-answer toggle showing the exact command, plus an all-at-once answer key for the whole lab.

Question 6

Does my progress save?

Accepted Answer

Not yet — all state is in memory and resets when you reload the page.
