If you want to build custom AI agents that do real work, n8n is the most capable and flexible platform you can pick.
You get visual workflows, built-in nodes for Claude, GPT, and Gemini, and a free self-hosted option that keeps your data in your hands. It asks more of you than no-code tools — there is a learning curve and you may host it yourself — but nothing else gives you this much control over how your agents think and act.
