Building AI applications is a fundamentally different kind of engineering. In traditional software, you write deterministic logic—sequences of functions where inputs map predictably to outputs, and bugs live in the codebase. With agentic pipelines, you’re designing systems where an LLM makes decisions on your behalf. You don’t control the output directly; you influence it through prompt design, retrieval strategies, tool orchestration, and careful observation of how the system reasons. This shift demands new skills, new tools, and a new way of thinking.
That’s one of the problems we set out to solve when we created Langflow. The idea was straightforward: give people a visual, open source environment where they could compose AI applications ...
