Where each one falls short

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

Contentful

  • Pricing model with content type limits (48) forces full tier upgrades
  • Limited GraphQL mutations for content management complexity
  • Requires significant technical expertise and developer dependency
  • Uncertainty following Salesforce acquisition announcement in June 2026

PubNub

  • Free plan storage history is limited to 7 days, which is short for apps needing longer message retention.
  • MAU-based pricing means costs scale directly with user growth, which can be less predictable than flat message-based pricing.
  • Pro-tier custom pricing above 50,000 MAU requires contacting sales rather than self-serve checkout.
