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.

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 / 5 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 / 24 days 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 1 month 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
These kinds of comparisons rarely lead to good discussions. Let's instead be focused and talk about real stuff. Consider https://learnpythonthehardway.org/ for example. It has influenced a generation of Python developers. Not just the main website, but the tons of Python code and Python-related content it inspired. Why would anyone write these kinds of textbooks/websites/guides if AI can replace them? Arguibly,... - Source: Hacker News / about 1 year ago
Try this instead: https://learnpythonthehardway.org/ LLMs will give you an uncertain percentage of wrong answers. Itโs like having a teacher that lies to you and doesnโt know when they are lying and has zero understanding of the information they give you. - Source: Hacker News / almost 2 years ago
Basic Python Knowledge: Ensure you have a solid understanding of Python basics. Resources like Python.org and Learn Python the Hard Way are great starting points. - Source: dev.to / almost 2 years ago

Also, I havenโt looked at it in a super long time but personally I got started with Python using https://learnpythonthehardway.org after originally training to be an artist and ended up having a pretty successful career in Pipeline instead. Source: about 3 years ago
