Langtrace
Analytics & Monitoring
From
FreeLangtrace: Open-source observability platform for LLM applications and AI agents with OpenTelemetry-based tracing, cost tracking, and performance analytics across 8+ model providers and 10+ frameworks.
Key Strengths:
- ✓True OpenTelemetry-native instrumentation: Emits standard OTLP traces and spans, so data can be routed to Grafana, Datadog, Signoz, or any OTel backend without rewriting collectors or losing data fidelity. Teams already invested in OpenTelemetry infrastructure can unify GenAI telemetry with existing microservice observability rather than maintaining a separate system.
- ✓Broad framework and model coverage: Auto-instruments 8 LLM providers (OpenAI, Anthropic, Gemini, Cohere, Groq, Mistral, Perplexity, Ollama) and over 10 frameworks and vector databases including LangChain, LlamaIndex, LangGraph, CrewAI, DSPy, AutoGen, Pinecone, Chroma, Weaviate, and Qdrant. This breadth covers most production GenAI stacks without requiring custom instrumentation.
AgentOps
Enterprise Agents
From
FreeDeveloper platform for AI agent observability, debugging, and cost tracking with two-line SDK integration.
Key Strengths:
- ✓Two-line integration makes adoption nearly frictionless for existing agent projects
- ✓Framework-agnostic design works with CrewAI, AutoGen, LangChain, OpenAI Agents SDK, and custom setups
