Apirelio vs Atatus API Analytics

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.

Atatus API Analytics monitors and analyzes REST, GraphQL, and WebSocket API performance in real time. It records endpoint latency at mean, median, P95, and P99 levels, and examines traffic spikes, geographic usage, endpoint distribution, and peak-load behavior. Dependency views map downstream calls and show third-party performance, external latency, and dependency health. Tracing can connect slowdowns to database queries, containers, external services, or code regressions. Automatic capture covers performance, errors, request volumes, payload sizes, and dependencies. Backend instrumentation uses Atatus SDKs or OpenTelemetry; full capabilities require analytics=true and logBody=true settings. Dashboards provide customizable views and alert thresholds with email, Slack, PagerDuty, and webhook channels. API Analytics integrates with Atatus APM and lists Kong Gateway support. Deployment options include web, API, and self-hosted environments, with on-premises traffic analytics. Pricing is on request, with a 14-day trial and no credit card required.
