https://github.com/yorzi/openui-rails

Render model-generated, streaming, interactive OpenUI Lang UI inside an existing Rails application without migrating the whole frontend to a React/Next.js SPA. Reuses the official, version-pinned OpenUI JavaScript runtime, keeps Rails authoritative for authentication, authorization and persistence, and ships an optional RubyLLM adapter. This is an unofficial integration and is not affiliated with, endorsed by, or maintained by Thesys.
