Why would anyone build with this?

REASON 1

Coordinate a continuous integration pipeline that watches a repo and runs builds automatically

REASON 2

Sync GitHub pull request activity into a versioned database other services can read

REASON 3

Build a workflow where multiple tools exchange data through one standardized, auditable hub

REASON 4

Use it as the coordination layer between a hypervisor and a desktop application, as Docker Desktop does
