    On a quick search I found Quest, but I remember there being more, some even had their own subreddits. Maybe I can look them up later. Source: about 3 years ago

  • good program for creating a puzzle based text adventure without any real programming?
    Surprised no one has mentioned Quest, it's complicated to figure out but it should be able to do everything you're asking, based on what I've seen other people do with it. Source: about 3 years ago
  • Shin Megami Tensei-style Dottore boss fight - made in RPG Maker MV
    It was just a text adventure in my case, but it had sounds and images playing when different choices were picked. It was about a hunt for a werewolf in the forests, just used as a test but I still recall it. It was a bit of a time ago, using it to learn pc and trying to make games out of fun, but I greatly recommend the program I used https://textadventures.co.uk/quest it is called Quest.

  • 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 / 15 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.
