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.
Langfuse TailScaleThey make the already great wireguard even better! Installation and configuration is a breeze, can easily connect to machines behind firewall(s) without altering anything.
Definitely made life easier.

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 / 15 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.

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
Tailscale + exit node for clean IP rotation. - Source: dev.to / 14 days ago
Tailscale is how every machine in the stack is reachable from outside the local network. All four machines are on the same Tailnet, which means I can reach any service from anywhere without opening ports or maintaining a VPN server. - Source: dev.to / 27 days ago
Still the most reliable setup, honestly. SSH into your machine over Tailscale (or Mosh if your connection is rubbish), reattach your tmux session, carry on. Free, works everywhere, been around forever. The downside is it's all terminal and you need to know your way around. Not exactly mobile-friendly either. Typing SSH commands on a phone keyboard is proper painful. - Source: dev.to / 3 months ago
The entire system runs on three machines connected via Tailscale mesh VPN:. - Source: dev.to / 3 months ago
ClickHouse's BYOC also uses an outbound-only channel for management traffic. Control-plane connectivity from the ClickHouse VPC to the customer's BYOC VPC is provided over a Tailscale connection that is outbound-only from the customer's BYOC VPC. ClickHouse engineers must request time-bound, audited access through an internal approval system; they can only reach system tables and infrastructure components, never... - Source: dev.to / 4 months ago
