Enterprise-grade webhooks service for outbound event delivery, featuring automated retries, signature verification, and an embeddable customer portal.
About Svix
Svix is an enterprise-grade webhook management platform designed to help developer teams send outgoing webhooks reliably without building custom infrastructure. Instead of worrying about delivery failures, retry logic, and security, engineering teams integrate Svix's API to dispatch events to their users with full visibility.
It offers a robust set of features including a white-labeled customer portal that can be embedded directly into SaaS products, allowing end-users to manage their own endpoints, inspect payload logs, and replay failed events. Svix focuses heavily on security and compliance, ensuring that all outbound webhooks are properly signed and authenticated.
