Since this is already "in context" for me from my saved items, it would also be fantastic to be able to self host the service on my home-server, raspberry pi, extra laptop or desktop, docker container, cloud VPS, etc. This would also allow us tech-dads to host user accounts for our children who would otherwise not be old enough to use the centralized/public instance.
For concerns about how to monetize for self-hosting, there could do a onetime payment of $50-100 to register/unlock full access.
