AI Nazar vs KeepRouter

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.

KeepRouter is a cloud API gateway that puts models from multiple providers behind one account. Its compatible chat models accept OpenAI Chat Completions requests at /v1/chat/completions and Anthropic Messages requests at /v1/messages, including use with Claude Code and the Anthropic SDK. The production catalog lists 101 models with public customer prices and supported endpoints. It covers text, image, video and speech output, with billing units varying by modality. The model named free charges $0.0000 per 1M input tokens and $0.0000 per 1M output tokens, supporting chat completions, streaming and tool calling where available. Paid usage uses prepaid USD credit rather than a recurring subscription. Keys can be restricted to model allowlists, while the raw key appears once at creation. Logs capture request operations without prompt or completion bodies. KeepRouter runs on Cloudflare’s global edge network, supports OpenCode and Continue setup, and says customer data is not used for model training.
