Apps built with Docker

Docker's practical contribution to teams here is making environments reproducible when the machines are not. Developers work on whatever hardware they have (mixed operating systems, varied versions, some quite old), and containers mean the application behaves the same on all of them and again in production. That removes a category of problem small teams cannot afford to spend days on. It also makes hosting portable: a containerised application can move between providers as pricing or latency changes, which is real leverage when infrastructure is billed in dollars. Onboarding gets faster too, since a new contributor runs one command instead of following a setup document that went stale months ago. Almost every serious backend product here uses it somewhere.
