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.

GhosttyGhostty might be a bit more popular than Langfuse. We know about 28 links to it since March 2021 and only 28 links to Langfuse. 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.
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. Adds a network hop.... - Source: dev.to / about 2 months ago
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
So I built a terminal. It's called viterm: a native macOS app in Swift + AppKit, with rendering handled by libghostty. MIT licensed. - Source: dev.to / 10 days ago
I made a nice way to use all your coding harnesses and persist them entirely in the TUI. I love Cursor and Claude Code, but I like using many of them and often use them in combination with tmux locally and via SSH, so I made this for myself really. Hoping other people find it useful or cool. It's mostly for use inside of Ghostty (https://ghostty.org/) so image rendering and everything works nicely. Would love some... - Source: Hacker News / 22 days ago
The downside of teaching a designer to use the terminal is that she will want hers to look like yours. Tanya saw my Ghostty theme and my catppuccin Starship theme over a screen share and decided she wanted both. Her Claude Code statusline came next. That's an entire other post. - Source: dev.to / 3 months ago
I built ghostty-automator, a purpose-built IPC layer for Ghostty that exposes the terminal's actual state to external processes. - Source: dev.to / 3 months ago
It works on any terminal that supports the Kitty graphics protocol โ Ghostty and Kitty are the two main ones. - Source: dev.to / 4 months ago
