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

Datadog

  • Consumption-based pricing model makes costs hard to predict and can scale quickly
  • Add-on modules significantly increase costs: custom metrics, indexed spans, extended retention
  • No free tier for production monitoring
  • High costs for organizations with large amounts of log data or high-cardinality metrics
