Automatically share WordPress posts on Pixelfed.
You choose which Post Types are shared—though sharing can still be disabled on a per-post basis. Posts without a Featured Image will not be shared. (The plugin currently doesn’t look for other images inside the post, that is.)
Supports a number of filter hooks for developers, and is fully compatible with WordPress’s new block editor.
More details can be found on this plugin’s GitHub page.
This plugin is available for download for your site.
