I am seeing so many posts on Google Gemini Code Wiki. But https://deepwiki.org/ has been around for quiet some time now.

Show HN: Sourcebot, the self-hosted Perplexity for your codebase
Just recently discovered Devins DeepWikis and love them. Same idea, talk to your repo, right? What does Sourcebot doe differently / better? https://deepwiki.org/. - Source: Hacker News / about 1 year ago

Your AI Agent Works in Dev. It Will Fail in Production. Here's the Math.
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 / 10 days 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 — step by step. - Source: dev.to / about 2 months 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 — prompts, completions, latency, token usage, cost — 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
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 / 3 months 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.
