Langtrace is an open-source, OpenTelemetry-based observability platform for LLM applications, providing real-time tracing, metrics, and evaluations for LLM APIs, frameworks, and vector databases. It offers SDKs for TypeScript and Python and can be self-hosted or used as a cloud service.

Use cases

• trace and debug LLM application calls
• monitor LLM API latency and costs
• add OpenTelemetry observability to LangChain apps
• self-host LLM observability dashboard
• evaluate LLM application performance
• track vector database usage metrics

When to choose

• you need OpenTelemetry-standard tracing for LLM apps
• you want to self-host your LLM observability stack
• you use popular LLM frameworks like LangChain or OpenAI and need metrics
• you need both Python and TypeScript SDK support

When to avoid

• you need general-purpose APM for non-LLM services
• you require a fully managed commercial support SLA
• AGPL-3.0 licensing is incompatible with your project
