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.

V (programming language)Based on our record, V (programming language) should be more popular than Langfuse. It has been mentiond 78 times since March 2021. 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 / 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 / 21 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.

How about v-lang? https://vlang.io/ Not python, but, go-like syntax, and satisfies other stuff you mentioned. - Source: Hacker News / 2 months ago
Somewhat similar language, https://vlang.io Itโs a mix of go and rust syntax that translates to C. - Source: Hacker News / 3 months ago
Language explorers looking for lower level languages like this may also want to take a peek at the V language. https://vlang.io/ I won't say with confidence either is better than the other; but I think both are worth a look. Odin (iiuc) always makes you manage memory; Vlang permits you to, but does also have linking to the Boehm GC that it will generate for you in most cases. Vlang and Odin in terms of syntax and... - Source: Hacker News / 6 months ago
There are other choices of languages, that are close to and influenced by Golang. Languages such as Odin[1] and Vlang[2] (which addresses several issues mentioned). Even more, they are at the stage where advance programmers can contribute or influence them in the ways that they might find satisfactory. Golang is too far down the road and cemented in its ways, to expect such significant changes in direction. [1]:... - Source: Hacker News / 11 months ago
> For me the biggest gap in programming languages is a rust like language with a garbage collector, instead of a borrow checker. https://vlang.io. - Source: Hacker News / over 1 year ago
