Attribution
Helio Stitch redistributes the typefaces below. Each is open source, and each one's notice and licence travels with it — that is what the SIL Open Font License and the Apache License ask of anyone who passes the files on, and serving a font to a browser counts as passing it on rather than embedding it.
Designs you make with these fonts are yours. Converting an outline into stitches does not make the stitch file a derivative of the font: the OFL says so directly, listing “manufacture objects based on their outlines”, “personalised fabric” and “3D-printed / laser-cut shapes” among the uses it permits with no further permission, and confirming that you remain the copyright holder of what you create. You can sell what you sew.

Typefaces
Each licence below is read from the font file's own name table, not from its npm package metadata. For some families the two disagree — an upstream relicensing that the packaging has not caught up with — and the string inside the file we actually distribute is the one that counts. Where they differ, the package's claim is shown too.

Software
Open source bundled into the Helio Stitch browser build and served to you, which is what carries a notice obligation — including source code we translated into our own and ship as part of it. Server-side components are not listed: nothing distributes them, so no notice is owed, and a precise public inventory of what runs on a server is mostly useful to someone attacking it. Versions are omitted for the same reason — no licence requires one.
