Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Couchbase

  • 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

SEMrush

  • Free tier limited to 10 reports per day across all tools
  • Keyword tracking capped at 500 per month on entry tiers (SEO and Starter plans)
  • Additional users cost £45/month per user above base subscription
  • Most advanced features require Advanced plan (£455.67/month), making entry cost significant for small teams
