Schedule Mastodon posts on any instance
Connect the instance you call home, write once, and Postlia publishes to your Mastodon account on your schedule — alongside your other channels.
Works with your instance
Type your instance's domain — mastodon.social or your own community server — authorize once, and you're publishing.
Queue or exact time
Drop posts into recurring weekly slots or schedule a precise date and time — the calendar shows everything at a glance.
Mastodon-specific captions
Fork the Mastodon version of a cross-posted update to fit its 500-character limit without touching your other channels.
Text and images
Publish text posts or attach an image — Postlia uploads it to your instance and posts through the official API.
How it works
Connect your instance
Enter your instance's domain and authorize Postlia on it — no developer setup on your side.
Write your post
Compose once, keep an eye on the 500-character count, and add an image if you like.
Schedule it
Pick a time, hit a queue slot, or post now — Postlia handles publishing and retries.
Frequently asked questions
- Which Mastodon instances does Postlia support?
- Any instance you can log into — Postlia registers with the instance you name during connect, so mastodon.social and self-hosted servers both work.
- Is there a character limit?
- Postlia validates against Mastodon's default 500-character limit and shows the count as you write. You can fork a shorter Mastodon caption when a longer post goes to other channels.
- Can I post images to Mastodon?
- Yes — attach an image and Postlia uploads it to your instance and publishes it with your post.
- Do I need to reconnect my account regularly?
- No — Mastodon access doesn't expire on a timer, so once connected your account keeps publishing until you revoke it.
- Is Mastodon scheduling free to try?
- Postlia comes with a 7-day free trial that includes Mastodon scheduling, the calendar, and queue slots.
