Docker

A platform that packages applications and their dependencies into portable containers, ensuring consistent behaviour across any environment (dev machine, staging, production).

"It works on my machine" is a classic developer problem. Docker solves it by packaging everything needed to run an app together. It's the standard for deploying apps to servers reliably.

A founder's developer uses Docker so the app behaves identically in development, staging, and production, no more "works locally, breaks in production" surprises during launches.
