Credits

Frontage is open source under the MIT licence. It is built on other people's work, listed here with where each piece came from and the terms it is used under. Every site credits its own fonts and photographs in its footer too.

The recipe

• Hallmark by Together AI, MIT licence, copyright 2026 Hallmark contributors. It sets each site's floor, theme and page shape, and runs the checks.
• Tasteskill (design-taste-frontend) for art direction, and Hairline (built on @lucasmarkes/hairline) for isometric line figures, used through Claude skills.
• three.js r160, MIT licence, copyright 2010 to 2023 three.js authors, for the 3D scenes.

Frontage is independent. It is not made or endorsed by Hallmark, Together AI or any of the projects above.

Fonts

Instrument Serif and Instrument Sans, SIL Open Font License 1.1, from Google Fonts. Each site lists its own faces in its footer. All are SIL OFL 1.1 from Google Fonts, except General Sans on Circle, by the Indian Type Foundry under the ITF Free Font License, from Fontshare. The full list, site by site, is in CREDITS.md.

Photographs

Stand-in photographs come from Wikimedia Commons files that are CC0, public domain, CC BY or CC BY-SA, through Hallmark's photo library. Each is credited with its author, licence and a link to its page in the footer of the site that uses it.

The brands

Every business here is a real kind of business with real facts, but every brand name is invented. Any likeness to a real company is unintended. Real places are named as themselves.
