# Interfaces

Interfaces is a paid digital magazine about design engineering by Jakub Krehel, covering animation, typography, layout, color, accessibility and interface craft. Each issue is a deep dive that combines writing, interactive demos and source code.

## Access

- Three issues are free and open to anyone. Everything else needs a subscription.
- Issue pages are at https://interfaces.dev/magazine/issues/<slug>. Markdown versions are at https://interfaces.dev/issues-md/<slug>.
- Requesting an issue page with `Accept: text/markdown` returns the markdown version.
- Paid issue HTML URLs redirect anonymous visitors to https://interfaces.dev/. Paid markdown URLs return 403 without a subscription. So do paid issue pages requested with `Accept: text/markdown`. Titles and issue numbers of paid issues are on the public pages. Descriptions are not.
- The magazine archive, the skills library and the tools library need a subscription and are disallowed in robots.txt.
