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 / 12 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 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. Adds a network hop.... - Source: dev.to / about 1 month 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
MockAPI: Provides simple mock data generation and configuration export/import capabilities, ideal for straightforward projects that don't require complex scenarios. - Source: dev.to / over 1 year ago
MockAPI allows users to create and host mock APIs easily. It features cloud-based accessibility, making it ideal for remote collaboration. MockAPI supports importing/exporting configurations and generating random data for responses. - Source: dev.to / over 1 year ago
Nuxt.js is a powerful framework built on top of Vue.js that makes it easy to create server-side rendered applications. One common task in web development is fetching data from an API. In this blog post, we'll walk through how to fetch mock data using MockAPI.io in a Nuxt.js application. - Source: dev.to / almost 2 years ago
I want to create a section in my app to store my favorite places in Menorca. I will use mockAPI.io it is a great service to build fake API and handle CRUD operations. - Source: dev.to / almost 2 years ago
The first step to interpreting it in a code is to create the API, I used the shareware service https://mockapi.io/ It is convenient to generate a REST API with a basic set of entities, such as users. - Source: dev.to / about 2 years ago
