Is Polkastarter on polkadot?

Excuse me, could you please clarify something for me? I've been hearing a lot about Polkastarter and Polkadot, and I'm wondering if there's a direct connection between the two. Specifically, is Polkastarter built on the Polkadot blockchain? If so, how does this relationship benefit Polkastarter and its users? I'm particularly interested in understanding the technical aspects of this potential integration and how it could impact the future of decentralized finance. Thank you for your time and consideration.
