The Mastodon Twitter Crossposter is a free and open source self-hostable tool which allows people to cross post between Mastodon and Twitter accounts. I wrote about first using the tool in an April Leaflet and then I published a comprehensive review based my experience with the Mastodon Twitter Crossposter in May.  While the Mastodon Twitter Crossposter can be self-hosted, I noted in both of my posts that I used the main instance run by the developer.  He explained that his public instance no longer works due to Twitter enforcing rules against how many statuses the app can post each hour:

Lately, with the whole Twitter change-of-hands, the crossposter went into a semi-functional state. A regular Twitter app can only post 300 statuses every 3 hours, in total. A developer, such as myself, can request elevated limits, which changes the limit to be per-user, instead of being a limit for the whole app.

The crossposter used to have these elevated limits since we had quite a few users for a while, but it was silently revoked and when I requested the increase, it was denied.

Thus, the developer is no longer accepting new sign-ups for his Mastodon Twitter Crossposter instance and will shut it down in January 2023.

Industrious users can still self-host the Mastodon Twitter Crossposter or look for an instance that is able to stay within Twitter’s limits for individual apps.  Moreover, the developer has stated that he will maintain an up-to-date list of alternatives for people who still want to cross post between Twitter and Mastodon.

To begin, I thank the developer, Mr. Renato Cerqueira, for running the public Mastodon Twitter Crossposter instance for several years.

For my part, I am no longer cross posting between Mastodon and Twitter (I stopped using the crossposter in November).  Instead, I am writing individual posts for New Leaf Journal articles on the platforms, tailoring our content to best take advantage of the capabilities of each.  You can find me on Mastodon at and on Twitter at @newleafjournal — feel free to follow if you have a Twitter account or Fediverse profile capable of following Mastodon (or Pixelfed).  In fact, you can find all of my online presences on my on-site profile, including RSS/ATOM feeds to said presences (where applicable — note that you can follow me on both Mastodon and Pixelfed via Atom).

I maintain my view that social media should not be necessary to find interesting content (see my essays on RSS/ATOM vs Facebook and Twitter and my thoughts on the Fediverse).  If you enjoy The New Leaf Journal, consider bookmarking our homepage, or, better yet, adding us to your favorite feed reader (even our newsletter has an RSS feed).
