Hi all,

disclosure first: I work at nxt Engineering GmbH, the company that built this.

We made Cloakey, a free browser-based generator for Keycloak login themes: https://cloakey.dev

You set colors, fonts, logo and layout in the browser, the preview renders the actual login components, and you download a deployable JAR (drop into providers/, select the login theme in your realm). It covers Keycloak 22 to 26 and 38 login page variants, from OTP and WebAuthn to the error pages. Packaging runs client-side, so nothing is uploaded and there is no account. It's built on Keycloakify. For now, it covers login theming only. Email theming is on our roadmap based on the feedback so far.

We're still collecting feedback, so if you try it, I'd like to know if you were missing any setting. There is a feedback button in the tool, and replies here reach me too.

Thanks,
Michael

Hi Michael, 

Would be great if you support login pages for SSO bridge and have option to hide login form as on https://github.com/ALMiG-Kompressoren-GmbH/tailcloakify

Hi Ivan,

Thanks for your feedback and for sharing the example. Both suggestions make a lot of sense. I've added them to our roadmap for consideration.

Best,

Michael
