API Analytics vs Apirelio

API Analytics monitors API activity and gives teams usage and performance data through a real-time dashboard, active monitoring, and error notifications. Setup examples cover frameworks including FastAPI, Flask, Django, Express, Gin, Rails, and ASP.NET Core. Its middleware can record request method, endpoint, user agent, timestamp, response status and time, API hostname, and framework identifier. IP collection is configurable: addresses can be stored, discarded after use, or never accessed or collected. An optional custom user ID can be attached to requests and used to filter information from the data API, which returns raw request records with filters such as date, hostname, status, location, and user ID. The service is available on the web and through an API, and it can be self-hosted. Its free plan costs nothing and supports up to 1 million stored requests per user; new requests replace older ones after the limit. The FAQ advises against production self-hosting while the project remains under development and testing.

Apirelio provides customer-aware observability for B2B APIs, linking errors, releases, and API versions to affected customers and integrations. Its explainable customer health score combines usage, reliability, latency, endpoint adoption, and regularity. Release comparisons use an equally long preceding baseline to identify endpoint regressions and affected customers. It can also compare a proposed OpenAPI contract with the current contract and connect risky changes to production traffic and customers. Integration journeys follow accounts from first connection through first success, production, adoption, and regular usage, helping surface stalled integrations. Alerts for inactivity, high error rates, or traffic drops can go to Slack, Teams, signed webhooks, or scheduled email recipients. The site lists framework integrations across PHP, JavaScript, Python, Ruby, Go, Java, and ASP.NET Core ecosystems. Apirelio says its SDKs do not capture request or response bodies, credentials, cookies, query strings, or client IP addresses as analytics dimensions. The Free plan lists 50K events per month, one project, 7-day retention, and one member. Growth costs $19 a month after a 14-day free period, with 2M events per month, five projects, 30-day retention, and five members.
