Since 2021, this technology is no longer widely available. It was removed from Firefox 85, and disabled by default in Chrome 84 and removed in Chrome 95. Using any of the offline Web application features at this time is highly discouraged and use of service workers is recommended instead. Cache manifests are distinct from web application manifests, a JSON-based file format which is part of the progressive web app technology, and as of 2023 is currently active and going through the standardization process at the W3C.
