Apirelio helps B2B software teams understand exactly which customers and integrations are affected when an API fails or changes. It correlates endpoint health, releases and version adoption with customer activity, producing explainable health scores, impact views and alerts without storing sensitive request or response payloads. Framework-native SDKs support Laravel, Symfony, Nette, Express, Fastify, NestJS, Nuxt and FastAPI, with setup designed to take minutes.
