Sister project to OpenLLMetry, but in Typescript. Open-source observability for your LLM application, based on OpenTelemetry

56
/ 100
Established

This project helps software developers building applications with Large Language Models (LLMs) to understand how their LLM calls and other components are performing. It takes your LLM application's operational data and integrates it with existing observability tools like Datadog or Splunk, providing insights into your application's behavior. The end-user is a software engineer or DevOps engineer responsible for building and maintaining LLM-powered applications.

389 stars.

Use this if you are developing an LLM-powered application in Javascript or Typescript and need to monitor its performance and interactions with LLM providers and vector databases using standard observability tools.

Not ideal if you are not working with Javascript/Typescript or are not building an LLM-centric application.
