Where each one falls short

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

Airbyte

  • The self-managed open source Core edition has no SSO or RBAC, no multiple workspaces, no row filtering or encryption, and no monitoring integrations
  • Sync frequency on Core is limited compared with the managed tiers, which offer 15 minute syncs
  • Support on the free tier is community and AI only; premium support requires Pro or Enterprise
  • The free Agents plan stops at 1,000 agent operations a month and pauses capacity until the next month once hit
  • Agent overages are billed per operation at $0.004 to $0.005 once past the plan allowance

Estuary

  • Per-GB pricing adds up quickly for high-volume scenarios
  • No transparent per-connector volume discounts below 6 connectors
  • Limited to data movement; transformation capabilities are basic
  • BYOC and private deployment requires enterprise plan
  • Smaller ecosystem compared to established alternatives
