Where each one falls short

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

Algolia

  • The free tier allows 10,000 search requests and 50,000 records a month
  • Billing is metered on two axes at once, search requests and indexed records, so a large catalogue with light traffic still costs
  • AI features require Grow Plus, where additional searches cost $1.75 per 1,000 against $0.50 on Grow
  • The Elevate tier requires an annual contract and is quote-only

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.
