Centrali vs Svix
Both handle webhooks reliably, but take fundamentally different approaches to storage and queryability.
Centrali
Centrali stores webhook events as queryable records in your backend. Inbound webhooks become data you can query, join with your own records, and keep indefinitely — not just delivery logs you discard after 90 days. Functions react to changes, and outbound webhooks deliver with HMAC signing and configurable retries.
Svix
Svix is a webhook-as-a-service platform focused on reliable delivery. It stores payloads for 90 days (customizable), provides 8 automatic retries with exponential backoff, and offers integrations with services like Shopflake and RabbitMQ. SOC 2 Type II, HIPAA, and PCI-DSS certified.
Feature Comparison
| Feature | Centrali | Svix |
|---|---|---|
| Compliance & Security | No SOC 2 Does not hold SOC 2 Type II, HIPAA, or PCI-DSS certification | SOC 2 II + HIPAA + PCI-DSS SOC 2 Type II, HIPAA, PCI-DSS, GDPR, CCPA, PIPEDA certified |
| Event Storage Model | Queryable records Events stored as queryable data in your collections, joinable with other records | Delivery logs Payloads stored for 90 days; primarily for retry and history, not querying |
| Retention Window | Indefinite Keep webhook events as long as you need for compliance, reconciliation, or auditing | 90 days default Customizable per-message, but limited retention periods |
| Retry Policy | Configurable 1–20 attempts, exponential or fixed backoff, up to 7-day retry window | Fixed 8 total attempts, exponential backoff, ~42 hour retry window |
| Dead-Letter Queue | Built-in Failed deliveries tagged with reason, queryable for manual inspection and replay | Operational webhook Sender notified of failure; no persistent DLQ in Svix itself |
| Serverless Functions | Built-in JavaScript functions that react to webhook events and other data changes | Not included Webhooks delivered; you handle processing separately |
| Inbound Webhook Replay | From durable buffer Replay inbound webhooks from the platform's buffer with provenance tracking | Not available Replay via sender's API or re-send from external source |
| Query Capabilities | Full platform query Use saved queries, joins, text search, and filters on webhook events | View-only Inspect payloads in Svix dashboard, no SDK query interface |
| Pricing Model | Usage-based Pay for operations and storage; webhook event ingestion included | Message-based Free tier (50k/mo), Professional ($490/mo), or Enterprise custom |
| Integration Endpoints | Custom via functions Use functions and workflows to route or transform before delivery | Advanced Shopflake, RabbitMQ, AWS EventBridge, database endpoints available |
Which should you choose?
Choose Centrali if you...
- You need to query historical webhook events as business data — join them with orders, users, or your own records
- Webhook payloads must outlive the sender's 30–90 day retention window for compliance, fraud prevention, or reconciliation
- You want to run functions (background jobs, data transformations) on incoming webhooks without a separate job queue
- You're building a backend where webhooks are part of the core data model, not just delivery notifications
Choose Svix if you...
- Webhook delivery reliability is your primary concern and payloads don't need long-term queryability
- You need HIPAA or PCI-DSS compliance (Centrali does not hold these certifications)
- You want advanced integrations with data warehouses, message brokers, or SaaS tools built-in
- You prefer a specialized webhook platform over a general-purpose backend
