Kobie is a modern spelling variant in the Koby-Kobe-Coby family. In most use it ultimately points back to Jacob-family short forms rather than to an independent traditional root of its own.
The spelling looks newer and more customised than Koby or Kobe, which is typical of modern English-language variant naming. Its appeal is mostly stylistic rather than historical.
