Svix is an enterprise-ready webhooks sending service that allows developers to build a secure, reliable, and scalable webhook platform in minutes. Webhooks enable applications to communicate automatically in real-time by pushing data when specific events occur, facilitating real-time data updates, resource efficiency, seamless automation, and simple deployment. They are commonly used in FinTech, AI, and logistics industries for automating tasks and triggering actions without human intervention. However, building webhooks in-house can be complex and time-consuming, tying up valuable engineering resources and reducing product velocity. A third-party solution like Svix takes care of the infrastructure complexity, allowing developers to focus on core product innovation while reducing operational overhead, risk, and time to market. The key considerations for building webhooks include reliability, security, scalability, quality of service, observability, and developer experience, which can be challenging to manage without proper tools and expertise.
