Finding quality CC0 (public domain) website templates can be useful for developers and designers who want to build websites without the licensing restrictions that typically come with other templates. Here are some recommended sources where you can find CC0 website templates:
GitHub – Many developers share their open-source website templates on GitHub. You can find CC0 templates by searching repositories with relevant keywords, and often, the licensing details are included in the repository’s README file.
OpenDesign – This is a community-driven platform where designers share their work for free under the public domain license. You can explore a variety of website templates that are freely available.
PublicDomainVectors – While primarily focused on vector images, some contributors also share website layouts and themes under the CC0 license. Browsing through their categories might yield useful resources.
Open Source Design – A hub for open-source design contributions, they periodically offer website templates among other design resources.
UnDraw.co – Known for illustrations, UnDraw also offers design assets that sometimes include basic website templates, all available under a CC0 license.
WordPress.org Theme Repository – While most are not CC0, some free themes here have very permissive licensing and can be adapted for various projects. Check the licensing details for each theme to ensure they meet your CC0 requirement.

When downloading and using these templates, ensure you double-check the licensing terms within each source to confirm they meet the CC0 criteria, as licensing can sometimes be miscommunicated.
