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.
LobbyStack is the open-source AI receptionist for calls, texts, and appointments.
Missed calls, slow replies, and manual scheduling cost small businesses real revenue. LobbyStack gives your business a 24/7 AI front desk that answers phone calls, responds to SMS messages, books appointments, handles reschedules and cancellations, and knows when to transfer the conversation to a human.
With LobbyStack, customers can call or text your business number and get help right away. The AI receptionist can answer common questions, collect caller details, take messages, qualify requests, offer available appointment times, send confirmations, and create follow-up tasks for your team.
Teams manage everything from a web dashboard: business hours, services, availability, receptionist instructions, phone numbers, call history, transcripts, recordings, tasks, and customer conversations. You can train the receptionist with your business details, FAQs, policies, documents, and website content, so it answers from approved information instead of guessing.
LobbyStack is built for appointment-based and service businesses that depend on fast customer response, including local services, professional services, repair businesses, agencies, consultants, clinics, wellness teams, salons, studios, and other teams that handle recurring customer calls and bookings.
Unlike most AI receptionist tools, LobbyStack is open source and self-hostable. Use the hosted cloud version when you want everything managed for you, or run it on your own infrastructure when you need more control.

Langfuse and LangSmith exist for this. Use them. The 30 minutes you spend setting up observability saves you the 87 hours you'd spend debugging blind. - Source: dev.to / 6 days 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 / 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 / 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.
