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.
Study-Track is a simple study planner that helps students map out their week and then track real progress. Create a weekly plan, add tasks, and see whatโs completed and what still needs attention. The app keeps you accountable with progress tracking, streak-friendly habits, and a clean UI designed to reduce friction and distractions.

Study-Track's answer:
React/Next.js (TypeScript), Firebase (Firestore + Cloud Functions), Stripe and Resend.
Study-Track's answer:
Study-Track is built specifically for students: it turns your class schedule into a simple weekly plan and then helps you track real progress. It combines planning, tasks, and deadlines with time-tracking and progress analytics, without feeling like a heavy project-management tool.
Study-Track's answer:
Because itโs designed for student life: fast setup, a clear weekly view, and an easy way to see whatโs done vs what still matters. Study-Track prioritizes focus and accountability (progress tracking and streak-friendly habits) instead of bloated features.
Study-Track's answer:
Students in higher education (university/college) who juggle lectures, labs, deadlines, and self-study time, and want a straightforward system to plan the week and measure actual study progress.
Study-Track's answer:
Study-Track started as a personal project: I couldnโt find a simple tool that helped me plan my week and actually see where my study time went. So I built something minimal and practical that I would genuinely use myself.
Study-Track's answer:
Early-stage product: used by students and small study groups (no โenterprise customersโ yet).

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 / 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.
