Mastodon scheduling with PostSyncer

Schedule Mastodon posts on any instance

Enter your instance URL, authorise PostSyncer and schedule posts with media, content warnings and the visibility each post needs. Because Mastodon is federated, your instance’s limits apply, and PostSyncer reads them when you connect.

A single workspace that connects your content, your team, and your schedule.

What you can schedule on Mastodon

Every format below publishes automatically at the time you choose. No reminders, no copying captions from another app.

Text posts

Plain-text posts with hashtags and mentions, counted against your instance’s limit.

Media posts

Up to four images or one video, with alt text and a sensitive-content flag.

Content warnings

Add spoiler text so the post is collapsed until readers choose to open it.

Visibility control

Choose public, unlisted or followers-only for each scheduled post.

Mastodon limits and sizes

PostSyncer checks these limits while you compose, so a post that schedules cleanly also publishes cleanly. Values are Mastodon’s published limits as of 2026.

Element Limit or size
Text 500 characters by default; instances can raise the limit
Attachments Up to 4 images or 1 video per post
Images PNG, JPG or GIF up to 16 MB
Video MP4 up to 99 MB
Content warning Spoiler text up to 500 characters
Visibility Public, unlisted or followers-only per post
Simple 3-Step Process

Best times to post on Mastodon

Mastodon has no ranking algorithm, so timing decides who sees a post. Publish when your followers’ time zones overlap, typically European mornings and US afternoons.

Read the full Mastodon timing guide →
  • Weekdays, 8–10 am CET
  • Weekdays, 1–3 pm ET
  • Avoid late night for public posts

Mastodon scheduling FAQ

Which Mastodon instances does PostSyncer support?

Any instance. Enter your server URL when connecting and PostSyncer authorises through that server.

Can I add a content warning to scheduled posts?

Yes. Add spoiler text in the composer and the post publishes collapsed behind the warning.

What is the character limit?

500 by default, but many instances allow more. PostSyncer reads your instance’s limit when you connect.

Can I control who sees each post?

Yes. Set public, unlisted or followers-only visibility per post.

Can I cross-post from X or Bluesky?

Yes. Short posts fit comfortably within 500 characters, and media and alt text carry across.
