Typefaces
GadNest uses the IBM Plex type family (IBM Plex Sans, IBM Plex Sans Condensed and IBM Plex Mono), designed by Mike Abbink at IBM together with Bold Monday and released under the SIL Open Font License 1.1. The font files are served from GadNest itself, so opening a page does not contact any third-party font service.
Photographs
Photographs on GadNest come from Pexels and are used under the Pexels License. We download each photo and serve it from GadNest, and we credit the photographer on the page where the photo appears and in the table below. The photos illustrate a topic; they do not show, test or endorse any product.
