Question 1

How do I self-host Svix webhooks?

Accepted Answer

Use Docker Compose to set up Svix with PostgreSQL and Redis, or deploy it standalone by configuring environment variables like SVIX_DB_DSN and SVIX_JWT_SECRET. The README provides step-by-step instructions for both methods.

Question 2

Svix vs webhook.site for testing?

Accepted Answer

Svix is for production-grade webhook delivery with reliability and security features, while webhook.site is a debugging tool for receiving and inspecting webhooks. Choose Svix if you need managed retries and signatures in live systems.

Question 3

Does Svix support asymmetric signatures?

Accepted Answer

Yes, Svix supports Ed25519 asymmetric signatures, though symmetric signatures are recommended for performance. Configure it by setting default_signature_type to 'ed25519' and using keys prefixed with 'whsk_' for endpoints.

Question 4

How to verify webhook payloads with Svix?

Accepted Answer

Use the SDKs to verify signatures based on the endpoint secret; for symmetric keys, check the whsec_ prefix, and for asymmetric, use the public key. The docs detail timestamp checks to prevent replay attacks.

Question 5

What are the dependencies for running Svix server?

Accepted Answer

Svix requires PostgreSQL for storage and optionally Redis version 6.2.0 or higher for task queues. It's written in Rust and can be compiled from source, but Docker is the easiest deployment method.

Question 6

Can Svix handle high volume webhook delivery?

Accepted Answer

Yes, Svix is designed for enterprise scale with connection pooling and queue management, but performance depends on tuning parameters like db_pool_max_size and ensuring Redis persistence to avoid bottlenecks.
