Mastodon Scheduler for Any Instance
Mastodon has no algorithm to resurface you — timelines are strictly chronological, so consistency is everything. Schedule posts to any server and keep your Fediverse presence active without living in an app.
- Works with any instance
- Images & alt text
- Cross-posting built in
Kadenzo is a Mastodon scheduler that works with any instance. Connect mastodon.social, fosstodon.org, or your own server, schedule posts with images and alt text, keep a chronological timeline active, and cross-post to Bluesky and Threads from one composer.
Schedule to any Mastodon server
No instance lock-in. Enter your domain — mastodon.social, fosstodon.org, your own server — connect, and your Mastodon posts slot into the same calendar and composer you use for every other network.
- Connect any instance — just enter the domain
- Schedule posts, images, and alt text
- Cross-post to Bluesky and Threads in one go

Why not just use most Mastodon clients?
The built-in scheduler covers the basics. Running an account needs more.
What actually works on Mastodon
A few habits that compound for personal brands.
Post consistently
Timelines are strictly chronological — there's no algorithm to resurface an old post. A steady cadence is the only way to stay visible.
Use a couple of hashtags
Hashtags are the main way posts travel across instances. Two or three relevant tags do far more here than they would on other networks.
Always add alt text
The Mastodon community takes accessibility seriously. Described images are expected — and posts that include alt text tend to earn more boosts.
Boost and reply
Reach comes from people, not a feed algorithm. Boosting others and replying genuinely is how your account gets seen.
Mastodon scheduling, answered
Which instances are supported?
All of them. Kadenzo connects through the standard Mastodon API — enter your instance domain when you connect, and you can add accounts from several instances side by side.
How do I connect my account?
Enter your instance domain (the part after the @ in your handle) and you'll be sent to that server to authorize Kadenzo — no password is ever shared.
Can I schedule images and alt text?
Yes — up to four attachments per post, matching Mastodon's own limits, each with its own alt text added before you schedule.
What's the character limit?
The default is 500 characters. Kadenzo counts as you type and lets you tailor the Mastodon version of a cross-posted update separately.
Can I cross-post to other networks?
Yes — write once and publish to Mastodon, Bluesky, and Threads together, with each platform's limits handled for you.
Works great with Mastodon
Cross-post and manage every channel from one calendar — schedule once and let each platform publish on its own.
Show up on Mastodon every week
Write it once, schedule the month, and build authority without living in the app.
