Where each one falls short

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

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.

Snyk

  • Free plan has strict test limits across all modules: Open Source (200), Code (100), Infrastructure as Code (300), Container (100) tests per month
  • Free and Team plans count only contributing developers making commits within 90 days; public contributions do not count
  • Enterprise plan requires custom pricing and sales contact
