langtrace and langwatch

Both are open-source LLM observability platforms built on similar architectures (OpenTelemetry-based tracing with evaluation capabilities), making them direct competitors in the same observability niche rather than complementary tools.

About langtrace

Scale3-Labs/langtrace

Langtrace 🔍 is an open-source, Open Telemetry based end-to-end observability tool for LLM applications, providing real-time tracing, evaluations and metrics for popular LLMs, LLM frameworks, vectorDBs and more.. Integrate using Typescript, Python. 🚀💻📊

This tool helps developers understand and improve their AI applications that use large language models (LLMs). It takes information about how your LLM application is running, including its interactions with LLM APIs, vector databases, and frameworks. In return, you get real-time traces, performance insights like latency and cost, and debugging tools to identify issues. This is for software developers and AI engineers building and maintaining LLM-powered applications.
