Honest question: Do you believe the pro subscription to your product is something you would pay $7/mo for? I find this price extremely high for a very small amount of data synchronized and maintenance costs.

The funny thing is that .cc domains are one of the cheapest domains and perhaps they run this on all free tier of Clerk,Supabase and vercel that they mention.

7$ is an insanely high price to have something for a monthly rate.

Just want to point out because of the number 7 as a reference but I have a vps which costs me 7$... per Year.

Edit: I think if the developer behind it is reading this, then perhaps I slightly recommend to actually follow towards a more donation based model. Its just my feeling that it might be very hard to sell at 7$/month but I feel like you wish to earn money from your project and that's very understandable and I wish you good luck in that even if it might be that many/most people in this website aren't the direct audience for this price-point :-)
