Helios

Developer-first observability for GenAI apps.

Visit Website →

Overview

Helios is a developer-first observability platform specifically designed for applications that use large language models. It provides end-to-end tracing, allowing developers to visualize the entire flow of their application, from user input to LLM calls and database queries. Helios helps teams to debug issues faster, create integration tests from real traffic, and gain a deep understanding of their application's behavior.

✨ Key Features

  • End-to-End Tracing
  • LLM and RAG Visualization
  • Automated Test Generation
  • Root Cause Analysis
  • Performance and Cost Monitoring
  • OpenTelemetry-native

🎯 Key Differentiators

  • Developer-first focus on debugging and testing, not just monitoring
  • Automatic test generation from production traces
  • Extends beyond just the LLM call to trace the entire application flow

Unique Value: Helios helps developers build more reliable GenAI applications by providing deep, end-to-end visibility and turning production issues into actionable tests, accelerating the debugging and development cycle.

🎯 Use Cases (4)

Debugging and troubleshooting generative AI applications Visualizing and understanding complex RAG pipelines Creating regression tests for AI applications Monitoring the latency and cost of LLM calls

✅ Best For

  • Troubleshooting complex microservice applications that use LLMs
  • Ensuring the reliability of AI agents before deployment

💡 Check With Vendor

Verify these considerations match your specific requirements:

  • Monitoring for statistical drift or bias in traditional ML models
  • Long-term model performance tracking

🏆 Alternatives

Langfuse LangSmith Datadog New Relic

Provides a more holistic, application-level view than tools focused solely on the LLM prompt/response. Its test generation feature is a unique capability not found in most other observability platforms.
