Zen Mesh Free Forever ($0) and Pro Early Bird ($29/mo, ref $49) are priced around real private webhook delivery, recovery, policy, and operational workflows — not just testing and inspection. Zen Mesh Business (V1.1 waitlist) and Enterprise (pilot) add dedicated infrastructure and team governance.

What is WebhookWhisper best for?
