Small update has been made, not big enough for a blog post.
We have added today new container types that offer MySQL plans only. The plans start at $0.04 making it far cheaper than any other plans with Databases. They also provide 2 databases to start with and goes up. This was designed for local apps and services that don't need web hosting along with the database.
The plans do have lower disk space, as most sites will use around 2-10% of the space for the database and databases are more resource intensive to run.
You can create one by clicking on create container just like before but now you will see a "Specialty" section with the new MySQL database option.
