As a Mac-using Python shop, we had serious file-sync performance issues when mounting our codebase inside a container via docker-compose. Nix completely freed us from them and allowed us to develop with Python natively speedily and without all the serious faff & headaches that usually comes with getting reproducible builds on everyone machines.

If you'd like to know more, I spoke at DjangoCon Europe late last year [1] on our setup; it's still paying serious dividends for us!

Happy to answer more.

This is great! Also directly answers some questions commenters have given elsewhere on this submission, e.g., 'why not Docker?'.

Yes! And it’s actually not either/or for us, we still use Docker Compose to run our services (Redis, PostgreSQL, etc) that don’t require file syncing with the host. It’s good at that.
