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.
LangfuseDevelopers looking for a collaborative and fast code editor with a modern interface would benefit from using Zed. It is especially suited for teams that require real-time collaboration capabilities.

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 / about 1 month 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 2 months 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 / 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 / 3 months ago
With Agent Client Protocol (ACP) you can keep the same UI and switch not models, but entire agents, that means using tools/prompts/compaction/etc that are tailored for the model. Try Zed[1] for GUI and pool[2] for TUI. [1] https://zed.dev/ [2] https://github.com/poolsideai/pool. - Source: Hacker News / about 2 months ago
Devcontainers + Claude + Pi [1] Zed https://zed.dev/ [2] Terminal threads https://zed.dev/blog/terminal-threads As sort of byproduct also replaced Alacritty + Zellij (i just don't have the need to use more, 3 weeks of new setup). - Source: Hacker News / 2 months ago
The simplest mainstream options for tools: 1) Claude Desktop which includes Claude Code for Anthropic: https://claude.com/product/claude-code (alternatively the terminal based version; either way get the subscription) 2) Codex for OpenAI: https://developers.openai.com/codex/app (same as above, subscription preferred instead of paying per token) 3) OpenCode for a variety of models: https://opencode.ai/ (they also... - Source: Hacker News / 2 months ago
That said, sometimes you do just want an editor, not a full blown IDE, and for that for the last few months I've been experimenting with Zed. It's okay. I've had some weird issues with their terminal emulator; I don't know what they are doing but my ZSH config doesn't load right so it sometimes gets stuck in what looks like an infinite loop, and then my PATH is all messed up... IDK, I expect my editors to kinda... - Source: dev.to / 2 months ago
This is a post-mortem, not a launch post. Paneflow is a native terminal workspace, splits, panes, branch-aware workspaces, session restore, built in pure Rust on top of Zed's GPUI framework and the upstream alacritty_terminal crate. It started as a port of cmux, a macOS-only Swift/AppKit project, and the Rust rewrite forced a string of decisions I had no good intuition for at the start. I want to walk through the... - Source: dev.to / 3 months ago
