Best Mastodon schedulers
Mastodon has no algorithm: people see what the accounts they follow post, in order, so a steady rhythm matters more there than anywhere. A scheduler keeps that rhythm without opening another app every day. This list says which tools reach Mastodon and which fits which job.
Who wrote this
Optimate publishes this page, so treat it as a vendor's list rather than an independent review. We've tried to earn the read by ranking on fit rather than on who's paying for the page — Optimate isn't first on every list here, and where a competitor is the better answer we say so and link you to them.
How this list is ordered
Ranked on Mastodon specifically: working with whichever server your account lives on, respecting that server's own character limit, reaching your other networks from the same calendar, and price for one to five accounts. Prices are from each vendor's published pricing; tools we haven't verified get positioning only. Which networks a tool reaches changes as platforms open and close their APIs, so confirm it on the tool's own site before you pay.
Pricing checked between 25 August and 24 October 2026. Tools without a figure are ones we haven’t verified directly — check their site rather than trust a number we didn’t read ourselves.
Number 1: Optimate
Free plan · Pro £29/mo · Studio £59/mo · Agency £135/moBest for: Mastodon beside your other networks, on any server
Schedules Mastodon posts on the same calendar as LinkedIn, Instagram, Facebook, X, YouTube, TikTok, Pinterest, Threads, Google Business and Bluesky. It works with any server, warns you when a post runs past 500 characters, and checks your server's own limit when it publishes, so a server allowing more gets the room it allows.
Number 2: Buffer
Free plan · from $5/channel/moBest for: A simple Mastodon queue with a free plan
A reliable queue with a free plan and per-channel pricing. Light on writing help, but the easiest way to start scheduling Mastodon alongside a couple of other networks.
Number 3: Publer
Free plan · from $5/account/moBest for: Bulk-scheduling Mastodon on a budget
Priced per social account, with bulk scheduling and post recycling, and one of the widest network lists of any scheduler.
Number 4: Postiz
Self-hosted free · hosted from $29/mo (5 channels)Best for: Self-hosting, or automating Mastodon posts
Open source, so a team that can run its own server pays nothing for the software, and it reaches Mastodon among over 30 networks. There's no shared inbox for replying to comments.

Common questions
Can you schedule Mastodon posts?
Yes, through a scheduler that connects to your Mastodon server. Optimate, Buffer and Publer all have free plans to start on, each with limits on accounts or posts, and Postiz is free to self-host.
How long can a Mastodon post be?
Most servers allow 500 characters, and some allow more. Mastodon counts every link as 23 of them, whatever its length. Optimate warns you when a post runs past 500, and checks your server's own limit when it publishes, so a server that allows more gets the room it allows.
Does it matter which Mastodon server I'm on?
It can. Before you sign up, check that a scheduler works with any server, not only the biggest one. Optimate connects to whichever server your account lives on.
