Is Polkastarter a dex?

Excuse me, I'm just trying to clarify something. I came across Polkastarter and I'm wondering if it's a decentralized exchange, or DEX, for short. From what I understand, DEXs allow for peer-to-peer trading of cryptocurrencies without the need for a central authority or intermediary. So, does Polkastarter fit into this category, or is it something else entirely? I'd appreciate any insight you can provide.
