## Details

## Overview

Langtrace is an open-source observability software that lets you capture, debug and analyze traces and metrics from all your applications, automatically capturing traces from LLM APIs/inferences, Vector Databases, and LLM-based Frameworks.

## OpenTelemetry Integration

Langtrace leverages OpenTelemetry standard traces across the most popular frameworks, LLMs, and vector databases to better understand the pathways and transformations within your LLM applications.

## Key Features

- Built with OpenTelemetry standards, avoiding vendor lock-in
- Integration with any observability platform: Signoz, Grafana, Datadog, Splunk, Logz
- Native tracing for over 30 popular providers
- Open source SDKs for capturing OpenTelemetry traces from LLM frameworks, vectorDBs and LLM providers
- End-to-end observability for LLM-powered applications
- Data privacy protection through self-hosting capability

## Semantic Conventions

Actively developing semantic conventions for:
- LLM clients
- Vector databases
- Agentic frameworks

## Recent Contributions

First official OpenAI instrumentation package that is part of the official OpenTelemetry contrib repository is live, contributed by Langtrace.

## Enterprise Features

Fully open sourced, enterprises can self-host and leverage Langtrace for end-to-end observability while protecting data privacy and ensuring effective use of underlying LLMs.
