Mastodon Scheduler — schedule toots to any instance
Queue Mastodon posts and auto-publish them across the fediverse, so you stay consistent on the open network without living in the app.
Mastodon's chronological, algorithm-light timeline rewards showing up regularly — which is exactly what scheduling is for. PostJay lets you queue toots and auto-publishes them to your instance, so you keep a presence on the fediverse without refreshing all day.
Write once and cross-post the same thought to Mastodon, Bluesky and X from a single composer, each trimmed to its own limit, and grow your open-network audience on autopilot.
