Where do the Transformer race come from?

I understand that the Allspark and Energon somehow give them life, but where do they actually "come from?" are they a technobiological race or did someone or something build them?

They come from Cybertron.

If you're wondering how they came to be created, well that's a bigger story, but here are the basics.

An alien race called the Quintessons found what would be Cybertron and used it's high metal content to create for themselves a pair of servitor robotic races- one based on consumer goods needs and the other operating as military hardware. 

The consumer goods race was enabled with simulation software enabling to modify their forms according to whatever was most useful for their environment. You need a wheeled vehicle? It scans one that seems to match the task and adjusts it form to emulate it.

The military hardware race was not so adaptable, but much more purpose driven. It could adjust it's form to one most suitable for it's combat mission. If the robot was a surveillance robot, it could transform into the most effective surveillance platform it had awareness of.

The consumer goods race became the Autobots eventually, and the military hardware race became the Decepticons.

Note this was 12 million years ago, so you can imagine there's a lot more history between that day and this one.
