I just built this little package:
It adds a little Icon to the toolbar, allowing you to quickly get a glimpse of how the current page will look on one of these social media plattforms:
- x
- telegram
- bluesky
- mastodon
- nostr
It will also tell you if the post matches the requirements (image dimensions, metadata) for those platforms.
Be aware, this is a local preview without crawling data from third party sources, if the requirements of the networks change, it has to be updated to be accurate.
Happy for feedback
