Colophon

The tools, libraries, and open-source projects LOOP HQ stands on.

LOOP HQ is built on a deep well of open-source work. The list below names the libraries we lean on most; the full dependency scan at /metrics/licenses is generated by pnpm licenses:scan and lists every package with its license. Anything flagged for manual review is captured in licenses/FLAGGED.md in the repo.

If you maintain a project we use and want your name added here, open an issue — we'd love to give you direct credit.

License compliance posture

We aim to use permissive-licensed dependencies (MIT, BSD, Apache-2.0, ISC, SIL OFL for fonts). Anything copyleft or source-available is reviewed before shipping — see licenses/FLAGGED.md for the current triage list.

[TODO: legal review — confirm posture and whether a NOTICE file needs to ship with production builds.]
