The short version

  • Only Airbyte has a free tier, so it costs nothing to try first.
  • Each has a real cost: Letta the Developer API plan charges $0.10 per active agent per month plus $0.00015 per second of tool execution on top of a $20 per month base and pay-as-you-go LLM usage, as of August 2026.; 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
