Ask HN: Is there a better alternative to Docker?

My company has been making use of Docker for a little while now and when it works it's great. Each developer runs their own OS as they choose. Most of us are on Mac but a few on Windows. Docker can be finicky on Mac--frustratingly so--but on Windows it's a nightmare.

Is there some alternative that works well across different platforms?

EDIT: To answer the question asked by @moondev; we mainly use Docker to mimic production environments as much as possible for local development. For example; if we have a client running a web application using Apache with PHP and PostgreSQL on AWS EC2 and RDS respectively we'll build two containers to match the versions of those products.
