Svix is a webhooks-as-a-service platform that handles the sending, retrying, and monitoring of outbound webhooks on behalf of other companies, so those companies do not need to build and maintain that infrastructure themselves.
Founded in 2021 by Tom Hacohen and backed by Y Combinator (W21), Andreessen Horowitz, and Aleph, Svix serves companies of all sizes that need to notify their own customers of events happening inside their product in real time.
Svix manages webhook delivery with automatic retries and exponential backoff, HMAC signing for payload verification, and message transformations and filtering so customers only receive the events they care about. It also provides an embeddable webhook management UI that companies can drop directly into their own product for their customers.
For larger customers, Svix offers typed event schemas, OpenTelemetry log streaming, and enterprise controls such as OIDC and SAML SSO, static source IPs, and on-premises deployment options.
Svix's Free plan includes 200 messages per second, 50,000 included messages per month, 30-day payload retention, and a 99.9 percent uptime SLA, with no credit card required.
The Professional plan starts around 490 US dollars per month and adds higher throughput, 90-day retention, white-label headers, static source IPs, and a 99.99 percent uptime SLA. Enterprise pricing is custom and adds a 99.999 percent uptime SLA, on-premises deployment, and dedicated account support.
