Webhooks are harder than they seem

Webhooks require a lot more engineering time, resources and ongoing maintenance than you would first expect.

Unreliable user endpoints

Customer endpoints fail or hang more often than you think. You need automatic retries to ensure deliverability.

Monitoring and reliability

You need to monitor the deliverability of your webhooks to different endpoints, disable failing ones and notify your customers.

Security implications

Webhooks come with a myriad of security implications, such as SSRF, replay attacks and unauthenticated webhook events.

Application Portal

You would need to build a UI for your users to add and remove endpoints, inspect logs and get ongoing reports.

Development experience

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

A whole lot more

You need to implement versioning, event types, and develop, maintain and scale an always running webhook delivery system.
Developers expect a certain level of deliverability and developer experience when it comes to webhooks, and I’m far too busy to provide it.
We send over 2M webhooks a month. We know the challenges, and we know we don't want to be solving them ourselves.
Svix gives our users a Stripe-level webhook experience, and it took us under five minutes to setup. This is a no-brainer.
I very much appreciate how much time Svix saved us. We were able to get a webhooks MVP out in less than a day.
