Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Amazon Aurora
- Aurora requires AWS ecosystem knowledge and integration with other AWS services
- Pricing can become expensive with high-traffic applications using many read replicas
- Limited support for non-relational data types compared to NoSQL alternatives
MotherDuck
- The free Lite plan caps compute at 10 hours per month, which limits it to light or hobbyist workloads.
- Business plan usage charges on top of the $250/month base can make costs less predictable than flat-rate competitors.
- There are no academic or non-profit discounts, unlike some competing data platforms.
- Annual billing requires going through a sales conversation rather than a self-serve toggle.
