I downvoted you. Here's why:

I've deployed SQLite to a large number of production software, from embedded systems to web servers handling thousands of daily vistors. In fact, SQLite is my tool of choice when it comes to a small/medium relational-db-based web project.

Sqlite is not a toy db. It is an impressive piece of software engineering.

So, unless you have a very narrow definition of the word production, you should do read up on SQLite (the official website is excellent) and seriously consider it for your next project.
