A Svix Alternative for Receiving and Forwarding Webhooks Into Private Infrastructure
Compare Svix and Webhook Relay. Svix sends webhooks to your customers; Webhook Relay receives third-party webhooks and forwards them to public, localhost and private destinations, with tunnels, transformations and cron, from $9.99/month.
Svix is one of the best-known names in webhook infrastructure, and for good reason: the team authored the Standard Webhooks specification, ships a fully open-source MIT-licensed server, and powers outbound webhooks for companies like Clerk, Resend and Lob. If you're evaluating it against Webhook Relay, the most important thing to understand is that the two products solve opposite directions of the webhook problem.
Svix helps you send webhooks to your own customers. Webhook Relay helps you receive webhooks from third parties and forward them anywhere — including into private infrastructure that has no public IP.
TL;DR
- Building a platform that sends webhooks to your customers? Svix is purpose-built for that, with an embeddable consumer portal, FIFO ordering and strong compliance.
- Receiving webhooks from providers (Stripe, GitHub, Shopify, CI) and routing them somewhere? That's Webhook Relay's job.
- Need delivery to localhost, an internal service or a Kubernetes pod? Webhook Relay's relay agent does this natively; Svix doesn't.
- Want tunnels and scheduled/cron webhooks too? Webhook Relay includes both.

Where Svix is strong
- Sending webhooks to your customers at scale. If you run a SaaS platform and need to deliver event notifications to thousands of customer endpoints — with retries, automatic disabling of dead endpoints, and customer notifications — Svix is built for exactly this.
- An embeddable consumer portal. Your customers get a UI to manage their own endpoints, inspect deliveries and replay events, without you building it.
- The Standard Webhooks lineage. Svix authored the spec that OpenAI, Anthropic, Google and others have adopted, so its signing and delivery conventions are well thought through.
- Open source and self-hostable. The MIT-licensed server is the same codebase as the hosted SaaS, which is attractive if you need on-prem or want to avoid lock-in.
- Compliance. SOC2, HIPAA and PCI coverage make it a comfortable fit for regulated platforms.
If you're a producer of webhooks and your customers are the consumers, Svix is likely the better fit and we'd happily point you there.
Where Webhook Relay is different
It's built for the receiving end
Most teams comparing these tools aren't trying to send webhooks to their own customers — they're trying to consume webhooks that someone else (Stripe, GitHub, Shopify, a CI system) sends them, and get those events to the right place. That "right place" is frequently not a public URL.
Delivery into private networks
This is the core distinction. A webhook provider can only call a public URL — but your handler often lives somewhere private. The relay agent makes an outbound connection and forwards webhooks to wherever you point it:
relay forward --bucket payments http://localhost:8080/stripe
# or an internal host with no public IP
relay forward --bucket payments http://payments.internal:9000/hook
No inbound firewall rules, no public IP required, including a first-class Kubernetes operator for delivering into your cluster. Svix delivers to your customers' public endpoints; it isn't designed to run a persistent agent into your private infrastructure.
Fan-out, transformations and cron in one product
Webhook Relay can fan a single webhook out to multiple destinations, reshape payloads in flight with JavaScript or Lua transformations, give you a static outgoing IP for allow-listing, and run scheduled (cron) webhooks — none of which are Svix's focus. It also offers general-purpose localhost tunnels and Service Connections to AWS S3/SQS/SNS and GCP Pub/Sub/GCS, so events can land directly in cloud infrastructure.
A free request inspector and a lower entry price
Svix doesn't offer a consumer-facing free request bin; Webhook Relay does — the free Webhook Bin lets anyone inspect incoming requests in the browser, no account required. And for small and mid-size teams, $9.99–$79.99/month covers a lot of ground before you reach enterprise tiers, versus a Professional plan reported around $490/month (as of 2026, verify current pricing).
When to pick which
- Pick Svix if you're a platform that needs to send webhooks to your own customers at scale, want an embeddable consumer portal, need a self-hostable open-source server, or need its compliance posture.
- Pick Webhook Relay if you need to receive third-party webhooks and forward them — especially into localhost, internal services or Kubernetes — or you want tunnels, fan-out, transformations and cron in one place at a lower starting price.
