There are multiple ways to get the Svix server up running. Docker is probably the most common, and you can use the official Svix Docker image from Docker Hub. We also have pre-compiled binaries here.

Designed for developers
Our simple yet powerful webhook API provides you with everything you need to offer a world-class webhook experience.
const svix = new Svix("sk_IrlFPEh3VYctuyHhKTCxamGV");
// Send an event to Rock Inc's webhook endpoints
await svix.message.create("rock_inc_uid", {
eventType: "user.created",
payload: {
username: "new_user",
email: "new_user@example.com",
},
});Webhooks are harder than they seem...
Automatic Retries
Customer endpoints fail or hang more often than you think. You need automatic retries to ensure deliverability.
Logs and Monitoring
Monitor the deliverability of your webhook endpoints, disable failing ones and notify your customers.
Security
Webhooks come with a myriad of security implications, such as SSRF, replay attacks and unauthenticated webhook events.
Application Portal
Stand alone and embeddable UI for your users to add and remove endpoints, inspect logs and view reports. Learn more
Development Experience
Offer your users a great developer experience, including the ability to test, inspect and replay their webhooks.

Support & community
Svix had a level of product maturity and a brand that we were very comfortable with putting in front of our customers. Brex customers have a certain expectation of us, and we need partners that can deliver at that level.
Managing our own webhook system was a nightmare... Ever since we added Svix we are all at ease. No more retries, no more endpoint failures, no random webhook errors. We had our best engineers working on it, and they are now free to focus on innovating on our product.
Svix's platform is reliable, fast, and makes our lives easier by handling the complexities of webhooks, allowing us to deliver a better experience for our users.
Adding Svix to the mix was definitely the right decision for us. In addition to happy customers, our engineers have their evenings back.
Svix's well-designed API and libraries enabled us to offer webhooks in a fraction of the time it would have taken us otherwise. Additionally, the responsiveness and feedback-friendly nature of the Svix team added immense value.
Integration gaps had cost us deals. Svix is how we get ahead of that – instead of chasing every integration request, we give developers the foundation to build what they need.
At my previous company (WorkOS) we had to build a lot of infrastructure internally to support webhooks. It was very complex, hard to maintain, so when I started Resend I already knew we didn't want to build webhooks ourselves.
We are extremely happy with Svix! It has helped us launch webhooks for our customers extremely quickly, the infrastructure is reliable, and it has saved us countless engineering hours.
I very much appreciate how much time Svix saved us. We were able to get a webhooks MVP out in less than a day.
