About telemetry.dev

telemetry.dev is an LLM observability platform for AI applications and agents, launched by maker Ephraim Atta-Duncan. Each request or agent run becomes one trace, and every model call, tool call and retrieval is a span with duration, tokens, cost and errors, so developers can debug failures and see where money goes.

It is built on OpenTelemetry: TypeScript and Python SDKs send standard OTLP/HTTP, or any existing OTel setup can export to it. Integrations cover OpenAI, Anthropic, Google Gen AI, Amazon Bedrock, OpenRouter and LiteLLM, frameworks such as Vercel AI SDK, LangChain, CrewAI and Pydantic AI, and coding agents like Claude Code and Cursor. Around tracing sit MCP analytics, prompt versioning with labels and rollouts, evals on datasets with LLM judges and human review, alerts for cost spikes, budgets and agent loops by email, Slack, Discord or webhook, and a read-only MCP server. Plans are billed per workspace by ingestion units: Free, Pro and Team.

It fits small teams shipping agents who want one tool for traces, cost and prompts. Datadog and Sentry offer AI monitoring inside much broader suites at higher cost. There is no self-hosting option, the company publishes no legal entity or address, and retention is short on lower plans.

On October 31, 2026 telemetry.dev launched on Product Hunt and finished #3 of the day. Buying tip: one span counts as one unit, so instrument a typical agent run and multiply before choosing a plan; Pro and Team keep ingesting above the allowance without automatic overage charges.

Key features of telemetry.dev

  • One trace per request or agent run with spans for every model and tool call
  • Token, cost, latency and error tracking per span
  • TypeScript and Python SDKs plus any OTLP/HTTP exporter
  • MCP analytics with failures and p95 duration by method and tool
  • Prompt versions, labels and rollouts without a deploy
  • Evals on datasets with LLM judges, code checks and human review
  • Alerts via email, Slack, Discord or webhook for cost, loops and errors
  • Read-only MCP server so an AI agent can investigate telemetry

  3. 3Testing a prompt change on a dataset before deploying
  4. 4Monitoring MCP server tool failures and latency
  5. 5Letting a coding agent query production traces via MCP

Best for

Small teams building AI agents who want affordable tracing, cost tracking, prompt management and evals in one OpenTelemetry-based tool.

Not ideal for

Organizations that need self-hosting, compliance paperwork or full-stack infrastructure monitoring (Datadog, Sentry).

Integrations

  • OpenTelemetry
  • OpenAI
  • Anthropic
  • Amazon Bedrock
  • Vercel AI SDK
  • LangChain
  • CrewAI
  • Claude Code

Our take

telemetry.dev is a lean, well-priced option for agent observability, and its OpenTelemetry base makes switching away easy later. Start on Free; move to Pro when you need longer retention or more than two seats.
