What do people build with it?

USE CASE 1

Test how your infrastructure handles 5,000 nodes without provisioning 5,000 real machines.

USE CASE 2

Iterate on Kubernetes tooling quickly against a simulated cluster instead of waiting on a real one.

USE CASE 3

Practice large-scale Kubernetes scenarios on your own machine instead of spending cloud credits.

USE CASE 4

Validate monitoring and orchestration tools by simulating failure scenarios before touching production.
