Best alternatives to Telemetry.dev in 2026
Once an AI app is calling multiple models, chaining tool calls, and pulling in retrieved data, figuring out why a response was slow, wrong, or expensive becomes genuinely hard with generic logging — you need to see the whole chain of model and tool calls as it actually happened. Telemetry.dev builds that view specifically for AI apps, capturing every model call and tool interaction as an OpenTelemetry trace you can inspect as a waterfall. It automatically tracks cost across more than 8,600 model identifiers — separating input, output, cached, and reasoning tokens, which matters a lot now that reasoning tokens can dominate a bill — alongside standard performance metrics like request volume, error rate, and p95 latency. It plugs into the major LLM providers (OpenAI, Anthropic, Gemini, Mistral, Cohere) and frameworks (LangChain, Vercel AI SDK) via drop-in TypeScript and Python SDKs, or standard OTLP if you're already emitting OpenTelemetry data. Privacy controls include per-environment capture settings, automatic secret redaction, and custom pattern matching before data is stored. The free tier covers 10,000 ingestion units a month with 7-day retention and no credit card required.
