Skills vs LangChain, LangGraph, MCP, and Tools: A Practical Architecture Guide

TLDR: These are not competing ideas. They are layers. Tools do one action. MCP standardizes access to actions and resources. LangChain and LangGraph orchestrate calls. Skills package business outcomes with contracts, guardrails, and evaluation. Most ...

LangChain vs LlamaIndex vs Haystack: What Two Weeks in Production Actually Taught Me

My team got handed a RAG project earlier this year — 40,000 documents, mix of PDFs and Confluence exports, users who would notice if answers were wrong. I'd used LangChain for smaller stuff before, but this was the first time I actually ran all three...

How to Develop Apps Using LangChain and LLMs

TLDR: LangChain is a framework that simplifies building LLM applications. It provides abstractions for Chains (linking steps), Memory (remembering chat history), and Agents (using tools). It turns raw API calls into composable building blocks. 📖 L...

Mastering Prompt Templates: System, User, and Assistant Roles with LangChain

TLDR: A production prompt is not a string — it is a structured message list with system, user, and optional assistant roles. LangChain's ChatPromptTemplate turns this structure into a reusable, testable, injection-safe blueprint. 📖 The API Contrac...

Guide to Using RAG with LangChain and ChromaDB/FAISS

TLDR: RAG (Retrieval-Augmented Generation) gives an LLM access to your private documents at query time. You chunk and embed documents into a vector store (ChromaDB or FAISS), retrieve the relevant chunks at query time, and inject them into the LLM's ...

OpenClaw vs LangChain: Why We Don't Use Frameworks

The first question people ask when they see our setup is: why not just use LangChain? It's the dominant Python framework for AI agents, it has a huge ecosystem, and it handles a lot of plumbing. The answer has to do with what "framework" means and wh...

How to Protect Sensitive Data by Running LLMs Locally with Ollama

Whenever engineers are building AI-powered applications, use of sensitive data is always a top priority. You don't want to send users' data to an external API that you don't control. For me, this happ

AutoGen vs LangGraph vs CrewAI: Which Agent Framework Actually Holds Up in 2026

Six weeks ago I shipped a research pipeline at work that needed to coordinate five agents — one to scrape data, one to summarize, one to fact-check, one to format, and an orchestrator to tie it all together. Before committing to a framework, I spent ...

AutoGen vs LangGraph vs CrewAI: Which Agent Framework Actually Holds Up in 2026?

Three weeks ago I was staring at a half-broken agent pipeline that was supposed to autonomously research competitors, draft summaries, and flag anything worth escalating to our product team. It worked maybe 60% of the time. The other 40% it either ha...
