Any server, one sign-in
Enter your server's address, like hachyderm.io, and approve MicroPoster on that server. Accounts on different servers can be connected side by side, and each shows its full address, like @you@hachyderm.io.
Mastodon automation
Automate Mastodon, on whichever server you use.
Crosspost new posts from X, Threads or Bluesky to Mastodon, or make Mastodon the source for your other networks, LinkedIn included. It works with mastodon.social, hachyderm.io, fosstodon.org and any other Mastodon server. Auto Repost can boost your own recent posts.

Getting started
Choose what happens to your Mastodon posts
Connect your accounts
Authorize your Mastodon account in MicroPoster. To crosspost, connect the other network's account too. Start with one account pair so you can check the result.
Choose crossposting or reposting
Create a crossposting automation with a source and destination, or choose Auto Repost for an account's recent posts. These are separate jobs with their own settings.
Check the first result
Activate the automation and review its history and destination posts. Check formatting and timing before expanding to more accounts.
What to know about Mastodon automation
Your server's limits, not a guess
MicroPoster reads each server's character and media limits and checks them again every month. A post is split into a reply thread only when it's longer than your server allows.
Boosts, not copies
Auto Repost uses Mastodon's native boost on eligible recent posts from your own account. Crossposting creates a new post; a boost reshares one that's already on your server.
Works with any Mastodon server
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.
Which Mastodon servers does MicroPoster support?
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.
Can I connect accounts on different Mastodon servers?
Yes. Each connected account keeps its own server and shows its full address, like @you@hachyderm.io. Every connected account counts toward your plan's account limit.
What can I automate on Mastodon?
MicroPoster offers automatic crossposting of supported new posts and native reposts of eligible recent posts from your own accounts. These automations work within your plan limits and require an active account connection.
Does Auto Repost choose my best-performing content?
No. It selects the oldest eligible post in a recent lookback of one to seven days, depending on the interval. Replies, reposts and posts already attempted by that automation are excluded. It does not rank posts by engagement.
Can it automatically add a promotional reply?
Auto Plug is planned, not available today. It is not included in the trial. Final network support, controls and a release date have not been announced.
Does it follow, like or reply to other people for me?
These publishing automations do not follow accounts, like other people's posts or send unsolicited replies. They distribute supported content and make native reposts from your own accounts.
How quickly does automatic crossposting run?
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.
Can I keep a post on just one platform?
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.
Do I need a credit card to try MicroPoster?
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.
