Traceloop

LLM reliability platform with open-source observability and evaluation

Overview

What Traceloop does

Traceloop is an LLM reliability platform designed to turn evaluations and monitors into a continuous feedback loop that improves every release. The platform provides comprehensive monitoring, quality evaluation, and debugging capabilities for LLM applications across 20+ LLM providers including OpenAI and Anthropic. Traceloop maintains close connection to OpenLLMetry, its open-source SDK built on OpenTelemetry standards, providing a lightweight instrumentation approach with just two lines of code. The platform sends observability data to 25+ popular observability platforms including Datadog, Honeycomb, and New Relic. Deployment options include cloud, on-premises, and air-gapped environments with SOC 2 and HIPAA compliance. Development support is available across Python, TypeScript, Go, and Ruby. The company is joining ServiceNow, representing a strategic shift toward broader enterprise integration and capabilities.

What people use it for

  • Monitoring LLM application performance in production
  • Instrumenting LLM apps with minimal code overhead
  • Continuous evaluation and quality scoring of LLM outputs
  • Debugging LLM application issues with full trace visibility
  • Integrating observability data into existing monitoring stacks

The honest half

Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Traceloop.

  • Free tier limited to 50k spans per month and 24-hour retention, restricting production use
  • Company acquisition by ServiceNow creates uncertainty about future roadmap
  • Requires integration with separate observability platforms for visualization
  • Less feature-rich than dedicated LLM evaluation platforms
