Running the Server

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.

For more info, check out the README.

Designed for developers

Our simple yet powerful webhook API provides you with everything you need to offer a world-class webhook experience.

Send a webhook with just one API call
JavaScript (TypeScript)
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",
  },
});

Sending webhooks is harder than it seems...

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.

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.

Resend

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.

FAQs

What is webhooks as a service?

Webhooks as a service refers to Svix's software as a service (SaaS) webhook platform. We've built a user interface for managing your users' webhook subscriptions as well as an API that simplifies the process of implementing webhook best practices at scale.

Why webhooks as a service?

Let your valuable engineering resources work on solving problems unique to your product. Leverage Svix for your webhook infrastructure to ensure deliverability, reliability, security, and scalability.

What is a webhook service?

A webhook service is similar to 'webhooks as a service' above, but also encompasses scenarios where the service is hosted by the service directly, rather than using the Svix WaaS offering. For example, a self-hosted instance of the Svix open source webhooks server would be considered a webhooks service.

Are your webhooks secure?

Yes! Our webhook service was designed for security from the ground up. We follow industry best practices, encrypt all data both in transit and at rest, and are comply with SOC 2 Type II, GDPR, CCPA and more.

Can you handle our scale?

We process billions of webhooks a year for our customers, and we power webhooks for top companies like Brex and Lob. We can most likely handle your scale, but please reach out if you have any specific questions or requirements.

Do you offer SLAs?

We offer uptime SLAs of 99.999% for our enterprise customers, 99.99% for our business tier customers, and 99.9% for our startup tier users.
