OpenLIT Typescript SDK is an OpenTelemetry-native Auto instrumentation library for monitoring LLM Applications, facilitating the integration of observability into your GenAI-driven projects. Designed with simplicity and efficiency, OpenLIT offers the ability to embed observability into your GenAI-driven projects effortlessly using just a single line of code.
Whether you're directly using LLM Libraries like OpenAI or Anthropic, OpenLIT seamlessly integrates observability into your applications, ensuring enhanced performance and reliability across diverse scenarios.
This project adheres to the Semantic Conventions proposed by the OpenTelemetry community. You can check out the current definitions here.

💿 Installation
npm install openlit
🚀 Getting Started
Step 1: Install OpenLIT
Open your command line or terminal and run:
npm install openlit
Step 2: Initialize OpenLIT in your Application
Integrating the OpenLIT into LLM applications is straightforward. Start monitoring for your LLM Application with just two lines of code:
import Openlit from 'openlit';
Openlit.init();
To forward telemetry data to an HTTP OTLP endpoint, such as the OpenTelemetry Collector, set the otlpEndpoint
parameter with the desired endpoint. Alternatively, you can configure the endpoint by setting the OTEL_EXPORTER_OTLP_ENDPOINT
environment variable as recommended in the OpenTelemetry documentation.
💡 Info: If you dont provide
otlpEndpoint
function argument or set theOTEL_EXPORTER_OTLP_ENDPOINT
environment variable, OpenLIT directs the trace directly to your console, which can be useful during development.
To send telemetry to OpenTelemetry backends requiring authentication, set the otlpHeaders
parameter with its desired value. Alternatively, you can configure the endpoint by setting the OTEL_EXPORTER_OTLP_HEADERS
environment variable as recommended in the OpenTelemetry documentation.
Example
Add the following two lines to your application code:
import Openlit from 'openlit';
Openlit.init({
otlpEndpoint: 'YOUR_OTEL_ENDPOINT',
otlpHeaders: 'YOUR_OTEL_ENDPOINT_AUTH'
});
Add the following two lines to your application code:
import Openlit from "openlit"
Openlit.init()
Then, configure the your OTLP endpoint using environment variable:
export OTEL_EXPORTER_OTLP_ENDPOINT = "YOUR_OTEL_ENDPOINT"
export OTEL_EXPORTER_OTLP_HEADERS = "YOUR_OTEL_ENDPOINT_AUTH"
Step 3: Visualize and Optimize!
With the LLM Observability data now being collected and sent to OpenLIT, the next step is to visualize and analyze this data to get insights into your LLM application’s performance, behavior, and identify areas of improvement.
To begin exploring your LLM Application's performance data within the OpenLIT, please see the Quickstart Guide.
If you want to integrate and send metrics and traces to your existing observability tools, refer to our Connections Guide for detailed instructions.
