The short version

  • Each has a real cost: 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; Asyncapi complex to implement and debug asynchronous operations due to their non-linear and concurrent nature
  • They diverge on capability: Airbyte covers Data replication, Asyncapi covers API Specification.

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

Asyncapi

  • Complex to implement and debug asynchronous operations due to their non-linear and concurrent nature
  • Keeping AsyncAPI documents up to date is challenging as systems evolve
  • Tracing and debugging asynchronous operations is more difficult than synchronous request-response patterns
