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.

Go is an open-source, statically typed, compiled language designed at Google for simplicity, reliability, and efficiency. It ships with a rich standard library, first-class concurrency primitives (goroutines and channels), and produces single, statically-linked binaries โ making it an excellent fit for microservices and containerised workloads. - Source: dev.to / 27 days ago
Unlike Go where the language definition itself via its compiler strictly enforces the inclusion of modules (i.e., include exactly what you use, no more, no less), neither the C nor C++ language definitions have an equivalent enforcement. This can lead to two problems:. - Source: dev.to / about 2 months ago
The difference was the language. OpenCode is written in Go. Aider is Python, Cline is TypeScript running in the VS Code extension host. For a tool that spends its time reading files, parsing diffs, and piping text to an LLM, Go's concurrency primitives and fast startup matter more than they should. OpenCode opens the repo, loads a file tree, and is ready to accept a prompt in under 150ms. Cline, running inside VS... - Source: dev.to / 2 months ago
I measured gateway overhead (not LLM response time) using a standardised Go benchmarking harness:. - Source: dev.to / 3 months ago
In this new series we will be creating an API written in go, using a framework like Chi, connecting to a PostgreSQL, and have it deployed to a site like Railway. - Source: dev.to / 3 months 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 / 3 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 / 22 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 1 month ago
