Hive-engine is the side-chain.
Hive-engine.com is just a website front-end.
Tribaldex.com is just a website front-end.

The team behind all of this is the same.
They stated they are stopping dev work on Hive-engine.com awhile back and all their resources are going into Tribaldex.com

these are NOT 2 separate DEX's.

Please undertand Hive-engine as a side-chain is different than hive-engine.com as a website.
