A Mastodon scheduling tool lets you write posts once and publish them on a set schedule. XreplyAI schedules Mastodon posts in advance for free, with 3 accounts and 30 queued posts on the free plan and no card required. It puts your Mastodon instance on the same calendar as 14 other platforms, alongside Bluesky and X.
Mastodon vs. a multi-platform scheduler
Some Mastodon clients can schedule a single post, and support varies by instance and client. None of them know about the rest of your platforms, so a post that should also hit Bluesky or X is a separate job. Read our roundup of the best social media scheduling tools for a full comparison.

|---|---|---|
| Schedule posts ahead | Varies by client | Yes |
| Queue-first posting rhythm | No | Yes: set once, auto-slot |
| Cross-post to Bluesky and X | Manual re-post | Yes, one entry |

| Everything queued in one view | Mastodon only | All 15 platforms |
| Cost | Free (native) | Free plan · Starter $9.99/mo · Pro $33.32/mo |
