- Built-in signature verification to prevent forgery
- Detailed delivery logs and event search
- Self-hostable for data privacy compliance
- SDK support in 10+ programming languages
What It Can't Do
- •Self-hosting requires managing PostgreSQL and Redis backups; free cloud plan has message limits and may incur costs beyond.
Use Cases
- SaaS platforms sending order status updates to customers
- Reliable payment gateway callback delivery
- IoT device state change event distribution
Detailed Introduction
Svix is a fully managed webhook platform that allows developers to send webhooks effortlessly. It abstracts away the complexities of delivery reliability, automatic retries, rate limiting, and signature verification. With multi-language SDKs (Go, Python, TypeScript, Java, Kotlin, Ruby, C#, Rust, PHP, Terraform) and both cloud-hosted & self-hosted options, Svix is designed for production workloads. The open-source server written in Rust can be deployed via Docker or compiled from source, backed by PostgreSQL and Redis. Ideal for SaaS platforms needing to send event notifications to external users securely and at scale.
Troubleshooting & FAQ (1)
TroubleshootingWhy do newly created Svix endpoints miss webhook messages sent shortly after creation?
Due to a caching issue in v1.x, the CreateMessageApp cache (30s TTL) is not invalidated when an endpoint is created, updated, or deleted. The delivery worker uses the stale endpoint list, causing missed deliveries. Workaround: Set environment variable SVIX_CACHE_TYPE=none to disable caching entirely. The permanent fix (cache invalidation on endpoint CRUD) is merged and will be available in the next OSS release.
