Update 9/3/24: Over at our Plugin Vulnerabilities service we did a security review of Neznam Atproto Share and found multiple security issues with the plugin. The developer so far has not addressed those.
Last week, the Twitter alternative Bluesky became publicly joinable after having previously required an invite code to join. Alongside that, there has been increased interest in automatically posting new WordPress post to Bluesky. There is a plugin to do that, though the name wouldn’t exactly suggest that. The plugin is named Neznam Atproto Share. The AT Protocol is networking technology that underlies Bluesky.
Setup is easy. On the Writing admin page in WordPress, you enter server information, including an App Password, which can be generated on the Bluesky website.
The plugin does have a major restriction we should note. It requires at least PHP version 8.0 to install it. A lot of websites are not using that version of PHP. You can get around that by manually adding the plugin in to WordPress and at least in our testing, it still seemed to work with an older version of PHP.
We have seen some complaints about problems with posting when it shouldn’t, so you should test out to make sure it works appropriately for your use case.
