description: >-
  Synthflow publishes exactly one commercial tier: Enterprise, sold through sales, with a
  stated floor of $30,000 annually. There is no self-serve plan, no free tier and no
  published per-minute or per-call rate card on the pricing page. Everything that would
  normally be a plan limit — call volume, concurrency, CAPS, telephony setup, integrations,
  security requirements and launch support — is described as scoped per contract rather
  than published as a number.

legacy_plans:
  status: retired
  names: [Pro, Growth, Agency]
  source: https://docs.synthflow.ai/concurrency-calling-limits
  note: >-
    Synthflow's concurrency documentation states that earlier Pro, Growth and Agency plans
    were issued with fixed concurrency limits, are no longer available for new
    subscriptions, and remain supported for existing customers whose limits are shown in
    their workspace or account terms. The self-serve tiers this catalog previously carried
    as a scaffold no longer exist as purchasable plans.

    status: being-retired
    note: >-
      Agencies could set their own pricing plans and rebill subaccounts through Stripe. The
      changelog entry of 2026-07-29 ("Stripe-based reselling is ending") deprecates this.

notes:
  - >-
    This file replaces a scaffold that asserted a free tier with 1,000 requests/month and
    a paid tier — values that were never published by Synthflow and are contradicted by
    the current pricing page.
  - >-
    apis.yml accessModel currently records pricing "free" and self-serve onboarding. The
    pricing page is enterprise/contact-sales only; app.synthflow.ai still accepts signups,
    so a product trial may exist outside the published plan set, but no free PLAN is
    published.
