Standard Webhooks
Standard Webhooks is an open-source initiative providing a set of tools and guidelines to send webhooks easily, securely, and reliably. It aims to standardize how webhook producers and consumers communicate, reducing fragmentation across the ecosystem and codifying industry best practices for security (SSRF, spoofing, and replay-attack protection), interoperability, and reliability.

Products & Services
An open specification defining conventions for webhook producers to provide consumers a secure, consistent, and interoperable interface, including a canonical signed payload and the webhook-id / webhook-timestamp / webhook-signature headers.
Open-source signature-verification reference implementations across languages: Python (PyPI), JavaScript/TypeScript (npm), Java/Kotlin (Maven Central), Rust (crates.io), Go (Go module), Ruby (RubyGems), and C# (NuGet).
Market Position
Positioned as the first broad, cross-vendor open standard for secure and reliable webhook delivery, contrasting with the fragmented status quo where each provider ships its own bespoke, varying-quality webhook signing and delivery scheme. It seeks to be the shared contract layer webhook producers and consumers can rely on across the ecosystem.

Founding Story
Standard Webhooks was initiated by Svix (a webhooks infrastructure company) after nearly a year of collaboration with partners across the industry, gathering feedback, exploring use-cases, and debating the specification. Rather than inventing new mechanisms, the initiative codifies existing industry best practices so companies can adopt them without breaking changes. The 1.0.0 specification was announced publicly in December 2023 alongside a Technical Steering Committee drawn from Zapier, Twilio, Lob, Mux, ngrok, Supabase, Kong, and Svix.
Business Model
Revenue Model
Standard Webhooks is a free, open-source specification and set of libraries with no direct monetization. It is stewarded by Svix, a commercial webhooks-infrastructure company, but the standard itself is community-driven and openly licensed; adoption carries no licensing cost.
