In June 2026, Loop Engineering swept through the entire AI engineering community.
Peter Steinberger's tweet with 6.5 million views, Boris Cherny's "I no longer prompt Claude, I write loops," Addy Osmani's official naming — three people, two weeks, one concept from the fringe to the center.
But concepts are concepts. When you actually want to implement Loop Engineering, you discover an awkward reality:
There isn't a single tool on the market that lets you build a production-grade Loop without writing code.
Claude Code and Codex require you to write configuration files in the terminal. LangGraph and CrewAI require you to write Python. Dify and n8n support visual design, but their essence is workflows — predefined paths, not autonomous loops.
