Apirelio is customer-aware API observability for B2B SaaS teams. It connects API failures, releases and version changes to the customers and integrations they affect—without capturing request or response payloads.

See customer impact during incidents, track version adoption, and use explainable health scores and alerts to prioritize the right accounts. Framework-native SDKs support Laravel, Symfony, Nette, Express, Fastify, NestJS, Nuxt and FastAPI, with setup designed to take minutes.
