AI Nazar vs Apirelio

AI Nazar provides observability for large language model API calls, with a dashboard for cost, latency, token counts, and errors. It supports OpenAI, Anthropic, and Gemini through wrappers around their official clients. The dashboard reports cost by request and model, tracks latency and errors, flags spend anomalies, and compares providers. Users can inspect prompts, responses, token counts, latency, and cost, then filter requests by model, provider, or status. Its TypeScript-first SDK offers a drop-in OpenAI client wrapper with streaming, function calling, and tool use. AI Nazar says telemetry is sent asynchronously without adding latency to API calls. The SDK and dashboard are open source under the MIT license. It can be used as a hosted service or self-hosted with SQLite, Postgres, or Postbase storage. By default, the SDK sends request metadata; prompt and response text are sent only when content logging is enabled. Hosted free-tier event data is retained for 30 days on a rolling basis. Dashboard usage and cost figures are estimates, not authoritative billing records.

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.
