F.A.Q.
Frequently asked questions
What Mastodon formats can postqueen schedule?
Text posts, galleries of up to 4 images, video, and full threads that publish as native reply chains. Upload media straight into the composer and preview the post before it goes out.
Which Mastodon servers does postqueen work with?
All of them. Enter your server's URL, sign in and authorize the app on your own instance, and repeat for accounts on other servers if you have them. Each connected account counts as one channel on your plan.
When is the best time to post on Mastodon?
Your followers are scattered across servers and timezones, so consistency beats any magic hour. Schedule regular slots, including times you are normally offline, and use analytics to see which windows earn boosts and replies.
Can I cross-post to Bluesky, Threads and X as well?
Yes. Write once, select all your microblogging channels, and adjust each version before it goes live. Mastodon's roomier 500 character default means you may want to trim the copies headed to tighter networks.
Can the AI assistant write Mastodon posts?
Yes. Drafts come out plain and human, which is what fediverse audiences expect, and stay within the standard 500 character limit. You choose when every post goes out, in the app, from the CLI, or through an agent using the MCP server.
What analytics do I get for Mastodon?
postqueen keeps a clean history of everything you scheduled to Mastodon and when it went out, right next to your calendar, so you can see your own cadence and repeat what worked. Live engagement numbers stay on your Mastodon instance, since the fediverse does not expose them through one central API.
Why did my scheduled Mastodon post fail?
Common causes are media above your server's upload limits, a server character limit lower than your draft, a revoked token, or the instance being temporarily down. Fix the post or reconnect the account and schedule it again.
Can I try Mastodon scheduling for free?
Yes. Cloud plans start with a 7-day free trial and unlimited posts. And since postqueen is open source under AGPL-3.0, self-hosting is free if you would rather keep everything on your own infrastructure.
