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.
Langfuse TestCompleteTestComplete is recommended for organizations seeking a reliable UI testing tool that supports both desktop, mobile, and web applications. It is especially beneficial for testers who appreciate the flexibility of choosing from multiple scripting languages or those who prefer a record-and-playback approach.

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 / 16 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.

Same approach works with Langfuse, Phoenix, Braintrust, or your existing OTel pipeline โ the metadata.userId pattern is the universal part. - Source: dev.to / about 2 months ago
I've been working with Selenium and Python for the past two years and I can say I've good enough experience with them about now. One thing that has always bothered me is how much manual work I have to do in order to implement the steps I need my program to make. So I've been thinking of making my own "step recorder", something in the vein of TestComplete. I've been using PyAutoGui too and the thought of crossing... Source: over 3 years ago
SmartBear TestComplete and Ranorex both offer 30-day free trials to try them out. Their suites make it easy to automate desktop apps, but licensing is expensive. Part of what you pay for is being able to write "codeless" tests by recording your mouse and keyboard activity and validating whatever you want on the app. Source: over 4 years ago
