It is a great project. I’m using it since two years and can only say good things. The maintainer is very responsive and most recently a change was made to both keycloak and keycloakify to future proof its approach to theming.

Currently it officially supports only apps made with create-react-app, but there is a vite branch in development and personally we use it with vite since a while.

Ooh, thanks for that. I work for a competitor and we're reworking our theming and this seems like a great project to review and model the rework after.
