By the creators of

Standard Webhooks

Svix has led the creation of the Standard Webhooks specification, establishing the first industry standard for secure and reliable webhook delivery used by modern developer platforms.

Adopted by top webhook senders, including:
OpenAI
Anthropic
Google
Supabase
Kong
ngrok

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.

Development Experience

Offer your users a great developer experience, including the ability to test, inspect and replay their webhooks.

A Whole Lot More...

Svix takes care of event types, message fanout, maintenance, scalability, and much more.

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.

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.

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.
