Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Couchbase
- The free tier is a single node with 8 GB of storage and forum support only
- Node rates are hourly and quoted as starting figures, from $0.15 an hour on Basic to $0.49 on Enterprise
- The Developer Pro and Enterprise plans require 3 nodes, so the hourly rate multiplies before any usage
- Backup storage is billed separately at $0.07 per GB a month, and analytics backups at $0.14
- Support response time is a plan feature, at 8 hours on Developer Pro against 30 minutes on Enterprise
- AI and analytics run as separately priced planes at up to $0.86 an hour per node
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.
