Magento 2 and third parts daily data import

Question

now I use Magento 1 and use Magmi for import data ( csv ) from third parts software.

I need to switch to Magento 2 and I know Magmi it's not available.

What do you use for import daily data into Magento 2? Do you use custom php interface ( with native Classes ), or there is something like Magmi?

P.S: we often use M2E for interface Amazon and Ebay.
