How Much Does Svix Cost in 2026?

Svix purpose-built the 'we send webhooks to our customers' problem. Different from Hookdeck (which purposeful-built 'we receive webhooks from third parties'). If you're Stripe/Shopify/Twilio and your customers subscribe to webhooks — Svix handles delivery, retries, customer-facing management UIs (event logs customers can check themselves), and endpoint verification. Free tier is remarkable: 50 messages/second, 50,000 messages/month, 30-day retention, 3 team members, 99.9% SLA — covers most SMB products end-to-end at $0/month. Professional at $490/month jumps to 400 messages/second, 90-day retention, 10 team members, 99.99% SLA (52 minutes downtime/year max) + fully unbranded customer experience (white-label) + connectors and transformations + static source IPs (critical for customer firewall allowlisting). Enterprise is custom with 99.999% SLA (5 minutes downtime/year max) + on-premise options + SSO + OpenTelemetry. The overage at $0.0001/message is aggressive: 1M messages above 50k free = $95 overage. 10M messages = $995 overage on Free/Pro. Filtered and retry messages are FREE — only attempted deliveries count. Where Svix wins: generous Free tier (50k messages/month, 30-day retention, 3 users at $0), purpose-built for outbound webhooks with customer-facing management, 99.999% SLA available at Enterprise tier (highest in category). Where it loses: Professional at $490/month is a big jump from Free — no mid-tier for teams graduating from Free, static IPs require Pro (Hookdeck includes lower), focuses on outbound only (need Hookdeck too for inbound use cases).
