About Svix
Svix offers a webhook gateway that handles sending, retrying, and monitoring events for your application. It works as both a hosted SaaS and a self-hostable open-source library, so you can start with the cloud service or run your own infrastructure. The service automatically retries failed deliveries, supports idempotency, and provides signed payloads for verification. It integrates with common frameworks and platforms including FastAPI, Django, Express, and serverless environments.
Svix tracks delivery status with a log dashboard and sends alerts when endpoints go down. The open-source core is written in Rust and licensed under MIT, covering the API server, webhook consumer verification libraries in multiple languages, and the database schema. The managed version adds rate limiting, dedicated IPs, and a 99.99% uptime SLA. Major adoption includes usage by companies like Clerk, Supabase, and several other developer platforms for their webhook infrastructure.
