Currently, Directus Extensions includes all Directus Extensions available on npm that adhere to the directus-extension naming strategy.
Ingestion happens automatically on a scheduled basis so it may be up to 20 minutes before any new extensions are added to the site, or updated versions are shown.
If you do not see your extension, make sure that it is named according to the Directus naming strategy starting with
directus-exension-***. I am considering allowing user submitted content in the future.
