The short version

  • Only Airbyte has a free tier, so it costs nothing to try first.
  • 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; Postscript carrier pass-through fees are billed on top of the per-message rate, roughly $0.00418 per SMS and $0.00841 per MMS in the United States, and are routinely missing from the cost comparisons buyers build.
  • They diverge on capability: Airbyte covers Data replication, Postscript covers Shopify segmentation.
  • Prices and features above were last checked on 31 August 2026.

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

Postscript

  • Carrier pass-through fees are billed on top of the per-message rate, roughly $0.00418 per SMS and $0.00841 per MMS in the United States, and are routinely missing from the cost comparisons buyers build.
  • The cheapest per-message rates require the $500 a month plan, so a small sender pays more than double the headline low rate per text.
  • The $0 Starter plan carries a $49 minimum monthly spend, so it is not a free tier and quiet months still generate a bill.
  • US SMS marketing carries real legal exposure under consent, quiet hours and carrier registration rules, and the compliance obligation sits with the merchant, not the platform.
  • It is SMS and MMS only, so email, push and on-site messaging live in a separate tool and audience suppression between the two has to be managed across systems.
