Thesys OpenUI is one answer: the agent declares a typed UI spec and the runtime renders interactive components, so an assistant can present a form or a set of controls as its response. The honest read: the headline \"6M downloads\" is an unverifiable npm claim, the name is badly squatted so you must install from the canonical `thesysdev/openui`, and this is a rendering runtime rather than a full agent framework — you still own the model and the logic. What is verified is the part that governs adoption: MIT read from the LICENSE file, self-hostable and free, and a repo that was pushed the same day it was checked."
