How to Schedule Posts on Mastodon in 2026

<h2>Mastodon Scheduling Basics</h2>

<p>Mastodon is decentralized, so scheduling works a bit differently than centralized platforms. You connect your specific Mastodon instance (e.g., mastodon.social, fosstodon.org, hachyderm.io) rather than a single global account.</p>

<p>Most scheduling tools only support mastodon.social. If you are on a different instance, make sure your tool of choice explicitly supports custom instances.</p>
