ronutz.com is open source. Its code is licensed under the Apache License 2.0, and its written content under Creative Commons Attribution 4.0 (CC BY 4.0). Both require attribution: reuse it, but credit the source. The open course materials are the one exception: each is released under the licence its own datasheet states, and the ones under CC0 1.0 ask for no attribution at all. The site is also built on other open-source software, credited below.

Open source: Apache-2.0 (code) and CC BY 4.0 (content)
The application code is licensed under the Apache License 2.0. The written content -- every Learn article, the tool copy and explanatory prose, and the documentation -- is licensed under Creative Commons Attribution 4.0 International (CC BY 4.0). You may use, modify, and redistribute both, including commercially, provided you give appropriate credit to Rodolfo Nützmann (ronutz.com), link to the license, and indicate any changes. ronutz.com remains the canonical, maintained source.
Open course materials: the CC0 exception
The course materials offered under Open materials (the slides as PDF and the editable deck with its speaker notes) are released under the licence each datasheet states, and the datasheet governs its own files whatever the site-wide badges in the footer say. Where that licence is CC0 1.0, the material is dedicated to the public domain: copy it, adapt it, translate it and teach from it, commercially or not, with no attribution required. Credit is appreciated, never required.
Open-source components
This site stands on open-source work. The site itself is built with Next.js and React and shipped as a static export; internationalization uses next-intl; the Learn content is rendered with next-mdx-remote, gray-matter, remark-gfm, and js-yaml; the HTML structure explainer parses with parse5 (and its dependency entities, BSD-2-Clause); and search is powered by Pagefind. These are provided under the MIT License, except next-mdx-remote (Mozilla Public License 2.0) and entities (BSD-2-Clause). The API reference embeds Swagger UI, under the Apache License 2.0. Each component stays under its own license, and the full notices ship alongside the source.
