Web3.0 Airbnb Project

If I copy the Airbnb Web3.0 youtube tutorial, will I need to change any of the code to have it run properly on a self hosted server as I can no longer access the Moralis hosted servers on the Moralis website?? I have an old version I previously deployed on a testnet but now I have re-deployed the smart contracts and want to run the same project on polygon mainnet. Is this possible to do on a self hosted server the same way it was done in the youtube tutorial?

Thank you

Some changes may need to be made - if authentication is used, it will need to be handled differently, and for event syncs, you can use the Streams API.
