Mastodon scheduler: schedule posts on mastodon.social or your own server

Mastodon is not one site, it is many servers that talk to each other, and your followers read their timeline in order, with no algorithm in between. That makes regular posting the whole game. You type your server's address, sign in there, and Posty publishes your posts at the time you set, next to your other accounts.

Your server, wherever it is

Your account stays where it is. You give Posty the server address, Posty registers itself on that server automatically, and then you sign in the way you always do. It works on mastodon.social and on smaller servers alike.

Room for a real thought

A Mastodon post is 500 characters by default, almost twice what Bluesky gives you. The Posty editor counts as you type, so you use the room without running into the limit.

No algorithm to outsmart

On Mastodon your followers see your posts in time order. There is no trick to learn, only the habit of showing up. With posts written ahead and scheduled, the habit takes a few minutes a week.

One calendar for the Fediverse and the rest

Mastodon sits in the same calendar as your other accounts, so a launch or an announcement is planned once and reaches every audience on the same day.

Plan, schedule and measure your Mastodon content from one place

Text, images and video on mastodon.social or any other Mastodon server, scheduled ahead.

REUSE

A Mastodon variant of your X or Bluesky post

In the editor you tune the same thought to Mastodon's 500 characters and tone, and you schedule it to every place in one go. You don't write it twice.

  • Per-account copy variants in the editor
  • A character counter as you type
  • One schedule, several social accounts

Images and video, straight from the media library

A post with a picture stops the scroll on Mastodon too. You attach images or a video in one click, and you see the finished post before it goes out.

RHYTHM

A steady presence without being online all day

On a chronological timeline, the post that goes out when your followers read is the one they see. You plan the week in one sitting, and the posts leave on their own.

  • Your own time slots, to the next free one
  • A weekly plan scheduled in one sitting

Take the Mastodon load off your shoulders

Write the next few weeks in one go, drag them onto the calendar, and Posty publishes at the minute you set. You only have to deal with the content.

Common
questions

Can I schedule Mastodon posts with Posty?
Yes. You connect your Mastodon account, write the post, pick a time, and Posty publishes it on its own. You can schedule text posts, images and video.
My account is not on mastodon.social. Can I still connect it?
Yes, any Mastodon server works. You type the server address (the part after the second @ in your handle), Posty registers itself on that server automatically, and then the normal Mastodon login opens there.
What is the character limit for Mastodon in Posty?
Mastodon's default is 500 characters, and the Posty editor counts against that as you type. Some servers allow more, but 500 is the safe length everywhere.
Can I schedule images and video to Mastodon too?
Yes. You attach images or a video from the media library, and everything appears together at the scheduled time. You check it in preview before it goes out.
How many Mastodon posts can I schedule at once?
There is no upper limit. In calendar view you can schedule a full month in one sitting.
Does Posty write copy for my Mastodon posts with AI?
No, and that is on purpose: Posty is the scheduler and the calendar, your own AI tool writes the copy. ChatGPT, Claude, Codex, OpenClaw, Hermes and Muse write and schedule the posts directly into Posty over MCP or the public API.
Does Posty have a Mastodon API?
Yes. The public REST API (api.posty.hu) is part of the Pro, Kreátor and Team plans, so you can schedule Mastodon posts from your own code too. Those same plans include the MCP server for AI agents. The command-line tool is included in the same plans; install it with npm install -g posty-cli.
Is there a free trial for Mastodon scheduling?
Yes, every new account starts with a 7-day free trial. We ask for a card to start the trial, but we don't charge anything during it. After that the Alap plan is available from $13 a month, and you can cancel anytime.
