- Formats: ttf, woff2
- Not allowed: Most fonts are SIL OFL 1.1, some Apache 2, the Ubuntu fonts use the Ubuntu Font License 1.0; each family folder has its own license file.
- Not allowed: OFL fonts cannot be sold by themselves, only bundled with software.
- Not allowed: Modified OFL fonts cannot use the Reserved Font Name.

AgentGid's catalog is curated: every entry was checked against the maker's official pages (registry, repository, license and pricing pages) on the date shown; a license value shows the quote it stands on wherever AgentGid has one. Usage numbers come from AgentGid's own scan of public repositories set up for AI coding agents. Claims by makers are reported, not tested by AgentGid.
