Traceloop
OpenTelemetry-native LLM monitoring and evals, one line of code to instrument.
What is Traceloop?
Traceloop is an LLM observability and eval platform built on the open-source OpenLLMetry standard, capturing prompts, responses, and latency with a single line of code. It is bought by teams that want OpenTelemetry-native LLM tracing without locking into a proprietary agent. Differentiator: open-source foundation means trace data stays portable across vendors.
Tools for building, hosting, testing, observing, connecting, and giving memory or computer access to AI agents.

Use cases to evaluate
Tracing LangChain and LlamaIndex apps via OpenTelemetry
Running automated quality checks on prompts in CI/CD
Monitoring latency and cost across 20+ LLM providers
Prompt management with version control
Fit to evaluate
Engineering teams already using OpenTelemetry
Open-source-first companies wary of proprietary agents
AI teams instrumenting LangChain, LlamaIndex, or Bedrock
Startups wanting free LLM observability up to 50k spans
Business fit
Right for you if you already run OpenTelemetry-based observability and want LLM traces in the same pipeline. Skip if you need built-in guardrails or runtime blocking, since Traceloop focuses on monitoring and evals rather than enforcement. The free tier covers 50k spans, enough for small production apps. Enterprise pricing is gated behind a call, so plan accordingly for compliance or on-prem needs.
How to evaluate Traceloop
Use this category when a business wants agents that do work across tools, APIs, browsers, and data sources.
Confirm the exact workflow
Map Traceloop to one concrete workflow first, such as tracing langchain and llamaindex apps via opentelemetry. Avoid buying before the owner, trigger, output, and success metric are clear.
Check category fit
Compare tool-calling, memory, browser automation, evals, observability, and deployment controls.
Compare practical alternatives
Shortlist Traceloop against Orgo, Browser Use, Browserbase so the decision is based on fit, effort, and workflow ownership rather than brand recognition alone.
