Postiz is an open source scheduler, which puts it in a category of its own. You can host it yourself for free, or use their hosted plan: $29 for five channels, $39 for ten, $49 for thirty, $99 for a hundred channels.
It covers about twenty networks, from LinkedIn to Mastodon, including Reddit, Discord, Slack, Telegram, Medium and Dev.to.
If you know how to deploy an app, Postiz will only cost you your server. That's unbeatable, and we won't pretend otherwise.
That model has a price, paid elsewhere: updates, the networks' API tokens, broken connections you fix yourself. For a developer, that's a known amount of time. For a consultant, it's an evening lost every time something breaks.
