Ably

  • Standard and Pro plans layer usage-based charges for messages, connection minutes, and data transfer on top of the base subscription, adding cost complexity.
  • The jump from Standard ($29/month) to Pro ($399/month) is steep for teams needing more than 10k connections but not full Pro capacity.

Hasura

  • Database support limited to PostgreSQL, MongoDB, ClickHouse, and MS SQL Server only
