AI Nazar

AI Nazar is an observability tool for large language model API calls, with a TypeScript SDK and a dashboard for request-level activity. It is best suited to teams building with OpenAI, Anthropic, or Gemini that want hosted convenience or control over self-hosted data.

Overview

The product brings cost, latency, token, and error monitoring together with inspection of individual requests. Its mix of a drop-in OpenAI wrapper, multi-provider comparisons, and self-hosting makes it a focused option for engineering teams tracking LLM usage across providers.

The SDK supports streaming, function calling, and tool use, and reports telemetry asynchronously. That is useful when instrumentation should not add latency to calls. The dashboard’s cost, latency, and usage figures are estimates, however, so they should not replace provider billing records for authoritative costs.

Key features

Monitoring and inspection

The dashboard tracks cost per request and model, latency, errors, and spend anomalies, and can compare providers. Request records can include prompts, responses, token counts, latency, and cost, with filters for model, provider, and status. This gives teams ways to investigate individual calls as well as broader usage patterns.

SDK, privacy, and deployment

The TypeScript-first SDK wraps the official OpenAI client and supports streaming, function calling, and tool use. OpenAI, Anthropic, and Gemini are supported through wrappers around their official clients. The SDK and dashboard are open source under the MIT license.

By default, the SDK sends request metadata; prompt and response text are sent only when content logging is enabled. The privacy policy describes TLS encryption in transit, encryption of sensitive data at rest, need-to-know production access controls, and hashed API keys. Self-hosted event data stays within the operator’s infrastructure, with SQLite, Postgres, or Postbase storage options. Teams that need hosted management can instead use the hosted deployment, but its free-tier event data is retained for 30 days on a rolling basis.

Pricing

Both plans are free, with no free trial. Hosted costs nothing and requires no card to get started; it includes managed storage and backups, zero infrastructure, and the same dashboard and feature set as self-hosting. It suits teams who prefer not to operate storage, with the trade-off of rolling 30-day event retention.

Self-hosted costs nothing, billed forever, and includes unlimited requests and API keys, the full dashboard, and no feature gates. It is the stronger fit for teams that want event data to remain in their own infrastructure and can manage deployment themselves. Unlike the hosted option, the plan specifies no request cap; it offers a choice of SQLite, Postgres, or Postbase.

Platforms

AI Nazar is available through an API, as a self-hosted deployment, and on the web. Its hybrid deployment model lets teams choose between hosted management and infrastructure they operate.

Who it's for

AI Nazar suits developers and teams monitoring LLM API calls across OpenAI, Anthropic, and Gemini, particularly those who value request-level inspection or want to keep event data within their own infrastructure. It is less suitable as a source of definitive billing totals, since its dashboard figures are estimates, or for users who need a provider beyond the three supported.

Pros and cons

• Pros: Both deployment options are free, and the self-hosted plan includes unlimited requests and API keys without feature gates.
• Pros: Request inspection combines prompt and response content, token counts, latency, and cost with practical filters.
• Pros: Metadata is sent by default while prompt and response logging is opt-in; self-hosted event data remains within the operator’s infrastructure.
• Cons: Hosted event data has a rolling 30-day retention period, which may not suit teams needing a longer history.
• Cons: Dashboard usage, cost, and latency figures are estimates, so billing decisions still need provider records.
• Cons: Provider support centers on OpenAI, Anthropic, and Gemini, and the stated SDK is TypeScript-first.

Alternatives

For a broader comparison of tools in the category, see API Analytics Software.

• API Analytics is another free option across API, self-hosted, and web platforms. Its free plan stores up to 1 million requests per user, replacing older requests with new ones; choose it if that explicit storage cap suits your needs.
• Apirelio is a freemium web option with a 14-day free trial of Growth at $19 a month afterward. Growth includes 2M events/month, 5 projects, 30-day retention, and 5 members; consider it if those project and team limits fit better.
• BetterMeter offers a free plan with 30-day event retention on API and web platforms; it may suit readers seeking another freemium option in those environments.
• Clavio is a web-based freemium product whose free plan offers sample datasets and file uploads, core analysis and charting, and limited saved analyses. It is oriented toward analysis and charting rather than the LLM-call monitoring described for AI Nazar.
• Helicone is a freemium option available via API, self-hosted, and web, and describes itself as open source. Consider it if you want to compare another open-source product with those platform options.
• KeepRouter offers a free API and web plan billed at $0 per input and output token, described as best-effort for testing, prototyping, and evaluation. It may fit those uses better than a monitoring-focused tool.
• Langfuse is freemium across API, self-hosted, and web platforms; its Hobby plan includes 50k units/month, 30 days of data access, 2 users, and GitHub community support. Choose it if those published usage and team limits suit your requirements.
• Moesif is freemium and supports API, self-hosted, and web platforms. Consider it if you want to compare another option in those deployment environments.

Verdict

AI Nazar is a strong fit for engineering teams that want free, open-source LLM request monitoring with a choice between managed hosting and self-hosted data. Its inspection and provider-comparison tools are the main reasons to choose it; look elsewhere if you need longer hosted retention or authoritative cost reporting from the dashboard.
