Langfuse is an open-source LLM engineering platform designed to empower developers by providing insights into user interactions with their LLM applications. We offer tools that help developers understand usage patterns, diagnose issues, and improve application performance based on real user data. By integrating seamlessly into existing workflows, Langfuse streamlines the process of monitoring, debugging, and optimizing LLM applications. Our platform's robust documentation and active community support make it easy for developers to leverage Langfuse for enhancing their LLM projects efficiently. Whether you're troubleshooting interactions or iterating on new features, Langfuse is committed to simplifying your LLM development journey.
LogRocket
LangfuseLangfuse might be a bit more popular than LogRocket. We know about 28 links to it since March 2021 and only 21 links to LogRocket. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
LogRocket takes error tracking to the next level by recording actual user sessions. Think of it as having a video replay of exactly what happened when an error occurred. Their free tier includes 1,000 sessions per month, which might seem limited but provides incredible value for debugging complex user interactions. - Source: dev.to / 4 months ago

LogRocket: Great for frontend UX teams who require detailed replays and product performance metrics. - Source: dev.to / 8 months ago
As a demo project, letโs try to rebuild something close to LogRocketโs landing page:. - Source: dev.to / about 1 year ago
LogRocket is a proficient tool in the realm of React debugging tools, designed to optimize the debugging process for developers. Through a highly-optimized JavaScript SDK and Redux middleware, LogRocket provides a robust platform for recording Redux data, network requests, console logs, JavaScript errors, and full DOM videosโโ. - Source: dev.to / over 2 years ago
In this project we will build a Python banking assistant agent using Strands Agents and make it observable and continuously evaluated using Langfuse โ step by step. - Source: dev.to / 23 days ago
Langfuse is the open-source standard for LLM observability. It traces every LLM interaction โ prompts, completions, latency, token usage, cost โ and provides the tooling to debug, evaluate, and optimize LLM applications in production. Think of it as "Datadog for LLM calls" with a focus on prompt engineering workflows. - Source: dev.to / about 1 month ago
You're monitoring production traffic. You need Langfuse / Phoenix / Helicone / Braintrust for that. Online eval is a different problem class: implicit feedback, drift detection, hallucination rates on your data, not on HellaSwag. - Source: dev.to / about 2 months ago
Gateway or proxy attribution. A reverse proxy in front of the model-provider API records the request, computes the cost, and exposes per-customer breakdowns. Open-source options include Helicone, LiteLLM, Langfuse, and OpenLLMetry. Hosted equivalents serve as the AI cost observability layer for teams that want centralized visibility: LangSmith, Datadog LLM Observability, Arize Phoenix.
