  • Strands Agents + Langfuse Evaluations
    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 / 16 days ago
  • Best AI Monitoring Tools in 2026: LLM, Agent, and MCP Observability Compared
    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
  • What is an LLM evaluation harness? A deep dive into lm-eval-harness
    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
  • How to track LLM costs per customer in production
    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 2 months ago
  • Per-user cost attribution for your AI APP
    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

  • How to Debug Encrypted API Traffic When Console.log Isn't Enough
    A Man-in-the-Middle (MITM) proxy sits between your client and the destination server, intercepting and decrypting TLS traffic so you can inspect it in plain text. Before you panic about the name โ€” this is a standard, legitimate debugging technique. Tools like mitmproxy have been used by developers for years. - Source: dev.to / 3 months ago
  • Overcoming Geo-Blocked Feature Testing with Zero-Budget DevOps Strategies
    Leverage open-source proxy tools like mitmproxy or tinyproxy, which allow you to intercept and modify HTTP requests and responses in real-time. By configuring these, you can simulate different geo conditions:. - Source: dev.to / 5 months ago
  • Kubernetes Egress Control with Squid Proxy
    I have had great experience scripting and running http://mitmproxy.org for these purposes. I also have set it in production as a dumb caching proxy for upstream services (We do a lot dumb GETs to list/enumerate). - Source: Hacker News / 7 months ago
  • Tracking outbound API calls from your application: why, what worked (and what didnโ€™t)
    We used mitmproxy. Itโ€™s lightweight, easy to run, and gives a clean log of every outbound request. - Source: dev.to / 11 months ago
