Agent frameworks
Build & orchestrate your own custom AI agents
Agent frameworks / agentic-AI orchestration platforms — developer and builder utilities used to construct, chain, and automate custom AI systems. Flowise and Langflow let you assemble an agent by dragging boxes on a visual canvas (no code); CrewAI is a Python framework for orchestrating a team of agents. All three are open-source and free to self-host. → Unlike general AI tools (ChatGPT, Claude, Midjourney) — end-user apps for direct prompting — these BUILD custom AI systems. And unlike "Personal AI assistants" (Hermes, OpenClaw), which you just install and chat with, here you build the agent yourself.
After this chapter you can
→ Build a working AI agent without writing code (Flowise / Langflow)
→ Turn your own PDFs into a grounded Q&A assistant (RAG)
→ Know when a visual builder is enough vs when to reach for a code framework
→ Orchestrate several agents into a collaborating "crew"
