Third-Party Licences

Ultimo aggiornamento: 2026-08-05

SVGized is built on open-source software. This page lists the components we use and the licences they are made available under, as required by those licences. It is provided by AKIO LLC.

This page is in English only. Licence texts are legal instruments and their English wording is the authoritative version; translating them would create a second, unofficial text.
