Schedule posts to Mastodon
Mastodon audiences are loyal, but the fediverse does not forgive silence. Crosspost talks to your instance's own API with a token you create yourself - it works with mastodon.social, a niche server, or your own - and keeps your presence steady with a queue and calendar.
Connect Mastodon in three steps
- On your instance, open Preferences, Development, and create a new application to get an access token (write scope).
- In Crosspost, open Channels, choose Mastodon, and paste your instance URL (https://mastodon.social or any other) plus the token.
- Compose once, tick Mastodon as a target next to your other platforms, and schedule it on the calendar.
What you can post
Text, image and carousel posts with the standard 500-character limit respected per instance in the caption editor.
Any instance, no special treatment
Mastodon is federated, and so is the connection: you point it at your instance URL. Move servers later and you just reconnect - your content library and calendar stay.
Crosspost without copy-paste
The same post can go to Mastodon, Bluesky and everywhere else in one action, each with its own caption. No more pasting into four apps every morning.
Ideas that fit the fediverse
The daily inspiration feed reads what is trending in your niche and hands you an angle plus an image idea - useful raw material for a text-first audience that hates canned marketing.
Frequently asked questions
Does it work with my instance?
If your instance exposes the standard Mastodon API (almost all do), yes. You supply the instance URL when connecting, so nothing is hardcoded to mastodon.social.
Is automated posting okay on Mastodon?
Posting through the official API with your own token is exactly what the API is for. Etiquette varies by server, so check your instance's rules - and keep the cadence human, which the calendar's spacing hints help with.
What happens if I revoke the token?
Publishing to Mastodon simply stops until you paste a new one. Tokens are encrypted at rest and never shown again once saved.
