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.
7-day free trial. Cancel anytime.
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, and every paid plan includes Mastodon scheduling, the calendar, and queue slots. A free account can try them with its first 3 posts.
