    As a web-based tool, SQL Fiddle requires an internet connection to access its features, which may not be suitable for offline work or conditions with limited connectivity.
  • No Persistence
    Data and schemas on SQL Fiddle are not persistent, meaning they can be lost over time or due to maintenance, making it unreliable for long-term storage or ongoing project work.
  • Limited Functionality
    SQL Fiddle may not support the full feature set or latest features of all database systems, potentially limiting its use for testing advanced or system-specific queries.

  • Anyone find D205 incredibly boring?
    D205 took 2 days and I actually loved it. I learned how much I like http://sqlfiddle.com. There is only one other class where you will use pgAdmin. I wouldn't have been able to pass the class so quickly if I didn't meet with the professor. Source: about 3 years ago

  • 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 / 11 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 1 month 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
