If you're researching webhook infrastructure, you've probably seen both Svix and EventDock. They sound similar — both deal with webhooks, both handle retries, both have APIs. But they solve fundamentally different problems.
This is one of the most common confusions in the webhook space, so let's clear it up.
The Key Difference: Sending vs. Receiving
The entire difference comes down to one question: are you sending webhooks or receiving them?
| Svix | EventDock | |
|---|---|---|
| Core function | Send webhooks to your users | Receive webhooks from providers |
| You are... | A SaaS building webhook delivery | A developer consuming Stripe/Shopify/GitHub |
| Direction | Your app → Customer servers | Provider servers → Your app |
| Problem solved | How to reliably notify your users | How to reliably receive notifications |
When You Need Svix
Svix is the right choice when you are the webhook sender. Specifically:
- You're building a SaaS product and need to notify customers when things happen (new order, payment processed, status change)
- Your customers expect webhook integrations — they want to receive events from your platform in their own systems
- You need a management portal where your customers can configure their webhook endpoints, see delivery logs, and retry failures
- You want to offer webhook delivery as a feature without building the infrastructure yourself
Svix handles the hard parts of webhook sending:
// Using Svix to SEND webhooks to your customers
import { Svix } from 'svix';
const svix = new Svix('your-auth-token');
// When something happens in your app, send a webhook
await svix.message.create('app_customer123', {
eventType: 'order.completed',
payload: {
orderId: 'ord_456',
amount: 9900,
currency: 'usd',
},
});
// Svix handles:
// - Delivery to the customer's endpoint
// - Retries if their server is down
// - Signature generation for verification
// - A portal for customers to manage their endpoints
This is a real engineering problem. Sending webhooks reliably to thousands of customer endpoints with different uptimes, response times, and configurations is complex. Svix is good at it.
When You Need EventDock
EventDock is the right choice when you are the webhook receiver. Specifically:
- You integrate with Stripe, Shopify, GitHub, or any provider that sends you webhooks
- You've had webhooks fail silently during deploys, outages, or bugs
- You need retries, dead letter queues, and monitoring for incoming webhooks
- You want automatic signature verification for major providers
- You want to stop worrying about whether your server was up when Stripe sent that payment event
EventDock sits between the provider and your server:
# Without EventDock:
Stripe --webhook--> Your Server
(down during deploy? event lost.)
# With EventDock:
Stripe --webhook--> EventDock (edge, always up)
|
+--> Your Server (retries, DLQ, monitoring)
# Setup:
# 1. Create endpoint at dashboard.eventdock.app
# 2. Get URL: https://in.eventdock.app/ep_abc123
# 3. Point Stripe at that URL
# 4. Set your server as the destination
# Done. 2 minutes.
Can You Use Both?
Yes — and some teams do. They're complementary, not competing.
If you're building a SaaS that both receives webhooks from providers (Stripe for payments, GitHub for CI) AND sends webhooks to your own customers (notifying them of events in your platform), you might use:
- EventDock on the receiving side — making sure you never miss a Stripe payment event or a GitHub push notification
- Svix on the sending side — reliably delivering your own webhooks to your customers' endpoints
They operate on opposite sides of the webhook flow and don't overlap.
Detailed Feature Comparison
| Feature | Svix (Sending) | EventDock (Receiving) |
|---|---|---|
| Retries with backoff | Yes (for outgoing deliveries) | Yes (for incoming deliveries to your server) |
| Dead letter queue | Yes | Yes, with one-click replay |
| Signature handling | Signs outgoing webhooks | Verifies incoming signatures automatically |
| Dashboard | Customer-facing management portal | Developer-facing delivery monitoring |
| Provider integrations | N/A (you are the provider) | Stripe, Shopify, GitHub, and more |
| Edge-native | No | Yes (Cloudflare Workers, global PoPs) |
| Self-hostable | Yes (open source) | No (managed service) |
| API-first | Yes (SDK for sending) | Yes (API for management, URL-based for receiving) |
| Idempotency | Event-type-based dedup | Built-in 24h deduplication window |
| Setup time | Hours (SDK integration in your codebase) | ~2 minutes (URL swap) |
Why People Confuse Them
The confusion makes sense. Both services:
- Use the word "webhook" in their marketing
- Offer retries and reliability
- Have APIs and dashboards
- Solve real infrastructure problems
But the direction is opposite. A simple test:
- "I need to send webhooks to my customers" → Svix
- "I need to receive webhooks from Stripe/Shopify/GitHub" → EventDock
- "I need both" → Use both
What About Other Options?
For Sending (Svix alternatives)
If you're looking at Svix for sending webhooks, other options include building it yourself (risky), using a message queue like SQS/RabbitMQ with custom delivery code (complex), or services like Hookdeck's outbound features.
For Receiving (EventDock alternatives)
If you're looking at EventDock for receiving webhooks, other options include Hookdeck (more features, more complex, usage-based pricing) or building your own reliability layer with queues and retry logic (weeks of work).
Frequently Asked Questions
Is EventDock a Svix alternative?
Not exactly. They solve different problems. Svix helps you send webhooks to your customers. EventDock helps you receive webhooks reliably. They're complementary, not competitors.
Can I use Svix and EventDock together?
Yes. Use EventDock on the receiving side (Stripe, Shopify, GitHub webhooks coming into your app) and Svix on the sending side (your app notifying your customers).
What's the difference between sending and receiving webhooks?
Sending: your app notifies other systems when events happen. Receiving: your app listens for events from other services. Different infrastructure is needed for each direction.
Is Svix open source?
Yes, Svix offers an open-source webhook server you can self-host. EventDock is a managed service running on Cloudflare's edge network.
Do I need a webhook service if I only receive from one provider?
Even with one provider, webhooks fail during deploys and outages. EventDock's free tier (5,000 events/month) covers most single-provider setups.
Receive webhooks reliably. EventDock adds retries, DLQ, signature verification, and monitoring to your incoming webhooks. Set up in 2 minutes, free for 5,000 events/month.
