Know a MariaDB champion? Submit a nomination
One of the things I really like about open source is that a project is never only about the software.

This is exactly why I’m very happy to announce the MariaDB […]

MariaDB Keeps Climbing: Community, Adoption, and Momentum
If you’ve been around the MariaDB community for a while, you can probably feel it already: things are moving in the right direction.
And no, I’m not talking about one vanity metric, one lucky spike, or one noisy social post.
I’m talking about a broader trend.
The latest Adoption Index data shows something I really like to see: not one lucky spike, but multiple signals moving in the right direction at the same time.
Sometimes people want one number.
