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

PostHog

  • The free tier covers 1M events, 5K web session recordings and 2.5K mobile recordings per month before usage-based billing starts
  • Accounts without a card on file are limited to 1 project; adding one raises it to 6
  • Data retention is 1 year until a card is added, which extends it to 7 years
  • Support is community-only until the account is on a paid plan
  • Error tracking is capped at 100K exceptions and surveys at 1500 responses per month on the free tier
