The short version

  • Only Azure SQL has a free tier, so it costs nothing to try first.
  • Each has a real cost: Azure SQL ecosystem lock-in limits flexibility compared to open-source or multi-cloud solutions; Clay two separate meters run at once, actions and data credits, and a plan can exhaust either independently
  • They diverge on capability: Azure SQL covers Intelligent Performance, Clay covers Data enrichment.

Where each one falls short

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

Azure SQL

  • Ecosystem lock-in limits flexibility compared to open-source or multi-cloud solutions
  • Managed service reduces control over database configuration and optimization tuning
  • Pricing complexity with consumption-based model can be unpredictable at scale
  • Less operational depth compared to Amazon RDS for advanced scaling scenarios
  • Azure PostgreSQL is less compelling than dedicated PostgreSQL providers outside Azure ecosystem

Clay

  • Two separate meters run at once, actions and data credits, and a plan can exhaust either independently
  • Data credit overage is sold at a 30% premium over the plan rate, so exceeding the allowance costs more per unit than planning for it
  • The free plan allows 500 actions, 100 data credits and 200 rows per table
  • The entry paid plan starts at $167 a month, and both paid prices are starting figures rather than fixed
  • The free plan cannot buy overage at all, so hitting the limit stops work rather than billing for it
