From the sources
Hook0 simplifies the integration of webhook for SaaS developers. With a single API call developers can ensure reliable event delivery, automated retries, and enhanced security for their products.
Hook0 is an Open-Source Webhooks-as-a-service (WaaS) that makes it easy for developers to send webhooks. Developers make one API call, and Hook0 takes care of deliverability, retries, security, and more. These teams chose Hook0 over competitors because Hook0 publishes its full server source (SSPL-1.0) and also offers production-ready SaaS support. They gain a competitive advantage by embracing extensibility, reversibility, and future-proofness in their integration strategies. Create an account, add your application, and list the event types your subscribers can receive. POST your event once. Hook0 delivers it, retries on failure, signs the payload, and encrypts over TLS.

Talanoa▲340Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself.
