X to Mastodon crossposting
Posting on both Twitter and Mastodon, or moving over slowly? Publish on X and MicroPoster copies your new posts to your Mastodon account. It does not import tweets you posted before the setup.

Getting started
Connect X, then enter your Mastodon server, like mastodon.social or hachyderm.io, and approve MicroPoster there. Check the full handle, like @you@hachyderm.io, before choosing it as a destination.
Create an automation from your X account to the connected Mastodon account. Activate it to copy supported new posts at your plan's check interval.
Publish a new X post and review its Mastodon copy. Check media, text breaks and account references against the requirements of the server you use.
Every Mastodon server sets its own limits. MicroPoster reads your server's character and media limits, so a long X Premium post is split into a reply thread only if your server needs it. Your server's community rules still apply.
This workflow creates a Mastodon post from your supported X content. It is different from a native Mastodon boost, which reshares an existing Mastodon post.
An X handle is not automatically the same person on Mastodon. Read the destination copy when you mention other accounts, and adapt network-specific references when needed.
Your Mastodon account lives on a server, also called an instance. MicroPoster connects to whichever one you use: enter its address when you connect, and MicroPoster reads that server’s own character and media limits, so a 500-character server gets a thread and a 5,000-character server gets one post.
Not on the list? Any other Mastodon server works the same way, including small community and self-hosted servers, as long as its admins allow new apps to connect.
Any Mastodon server. Popular ones include mastodon.social, mastodon.online, mstdn.social, mastodon.world, hachyderm.io, fosstodon.org, infosec.exchange and techhub.social, and small community and self-hosted servers work the same way, as long as their admins allow new apps. Enter your server's address when you connect.
Yes. Use Mastodon as the source and X as the destination in a separate automation. X's content requirements and your plan allowances apply to the resulting post.
No. Source and destination posts are separate. Editing one does not automatically update the other through MicroPoster.
MicroPoster checks for new posts at the interval included in your plan. Crossposting is not instant. Platform availability, media processing and your remaining allowance can affect when a post is published.
Yes. Add #nocrosspost or #keephere to the post, or a reply in its thread, to skip it in automatic crossposting. You can still crosspost it manually from your dashboard.
No. New accounts receive a 7-day trial under the Creator plan limits. A trial without payment details does not automatically become a paid subscription. Check Pricing for the current account limits and allowances.
