Svix Webhook Service

Svix is an enterprise grade webhook infrastructure service that enables companies to ship reliable customer facing webhooks in days rather than quarters. Founded by Tom Hacohen and backed by Y Combinator and Andreessen Horowitz, the platform delivers billions of webhooks for customers including Brex, Benchling, Replicate, Clerk, PagerDuty, Twilio, Resend, Drata, Chargebee, and Gopuff. Svix created and maintains the Standard Webhooks specification, establishing the first industry standard for secure webhook delivery adopted by OpenAI, Anthropic, Google, Supabase, Kong, and ngrok. Core features include automatic retries with exponential backoff for failed or hanging endpoints, comprehensive logs and monitoring for deliverability tracking, automatic endpoint disabling for persistently failing destinations, and robust security protections against SSRF, replay attacks, and unauthenticated webhook events. The embeddable application portal lets customers self manage their webhook endpoints, inspect delivery logs, and view reports through a white labeled UI that drops into any dashboard with a single line of code. SDKs are available in 10 languages including TypeScript, Python, Go, Java, Kotlin, Ruby, Rust, PHP, and C-sharp. Security and compliance certifications include SOC 2 Type II, HIPAA, PCI-DSS, PIPEDA, GDPR, and CCPA with multi region data residency support. Additional products include Svix Ingest for receiving webhooks at scale and Svix Play for inspecting and debugging webhooks in the browser.
