Why Semi Design Copied Ant Design and How It Responded
The article explains how Douyin's Semi Design, an open‑source React UI design system, was found to contain undocumented Ant Design text, details the team's public apology, the architectural differences, license updates, and the specific components that were referenced.
Douyin's frontend team recently open‑sourced its enterprise UI design system, Semi Design, which provides a complete, easy‑to‑use solution for modern admin applications, including a design language, React components, and theming.
Shortly after release, parts of the repository were discovered to contain undocumented text copied from Ant Design. On October 27, the team publicly admitted the oversight, apologizing for not crediting Ant Design.
The team clarified that Semi Design has been maintained for over two years, built on a Foundation/Adapter architecture that differs significantly from Ant Design, and that the project will continue to accept community feedback while adhering more strictly to open‑source licensing rules.
They have updated the license and added proper attribution. The statement lists the specific references:
Code references: Ant Design, rc‑tree (used in Grid, Tree, Typography components)
Technical principles or API design references: informed, formik, Material Component Web (used in BaseComponent, Form)
Images illustrating the statement and the referenced components are included below.
