In Jainism, Krishna is generally referred to as Vasudeva Krishna or simply Vasudeva.

In Jain tradition:

• Krishna is not worshipped as God the creator.
• He is seen as a great historical figure and a Vasudeva, one of the powerful heroic rulers described in Jain cosmology.
• His brother Balarama is considered a Baladeva.
• Their opponent Jarasandha / Jarakumar is often described among the Prativasudevas in Jain texts.

So, in Jainism, Krishna is mainly known as a Vasudeva, not as an all-powerful supreme deity.
