       XPost is a social media cross-posting tool that differs from others by using streaming APIs to allow instant, zero-input cross-posting. this means you can continue posting on your preferred platform without using special apps.

       -
       XPost tries to support as many features as possible. for example, when cross-posting from mastodon to bluesky, unsupported file types will be attached as links. posts with mixed media or too many files will be split and spread across text.
