Postwright vs Postiz
Postiz is an open-source social media scheduler with AI agents, 30+ networks, and a visual calendar, run on Postiz Cloud or on your own server. Postwright is a Mac app you buy once that publishes your blog, your newsletter, your social posts, and your video, in the order those channels depend on each other.
If the job is social posts across a lot of networks, with a team working in one place, Postiz covers more ground. If the job starts with a blog post that a newsletter and a handful of social posts need to point at, that ordering is what Postwright is built around.
Side by side
| Postiz | Postwright | |
|---|---|---|
| Price | Cloud: $29–$99 a month by channel count ($23–$79 billed yearly), 7-day trial, no free Cloud tier. Self-hosted: free under AGPL-3.0. | Studio (the video engine): free with the Step Zero newsletter. Pro: $199 once. Team: $499 once. |
| Where it runs | Postiz Cloud, or your own server (Next.js, PostgreSQL, Redis, Temporal) | Your Mac (Apple silicon, macOS 14 or later) |
| Social networks | 30+, including X, TikTok, Pinterest, Bluesky, Reddit, LinkedIn, Instagram, and YouTube | YouTube, LinkedIn, Facebook Pages, Instagram, and Threads |
| Blog | Posts to WordPress, Medium, Dev.to, and Hashnode | Commits the post to your git repo, pushes, and polls the live URL until the page answers. A static-site folder or signed webhook also works. |
| Newsletter | Listmonk as a channel | Its own engine: Resend or Mailgun from your domain, double opt-in, drip sequences, and a list that lives on your Mac |
| Video | AI clipping from a YouTube video, 60–600 minutes a month depending on plan | Clips any long video you drop in a folder, plus videos from your phone, cut on your Mac with ffmpeg. Free in Studio. |
| Order between channels | I found no way to make a post wait for another channel’s live URL. RSS auto-posting reacts to new feed items. | Blog first, then the newsletter once the post’s URL answers, then social posts carrying that link |
| Teams | Unlimited members, roles, and client groups from the Team plan up | Pro is one operator. Team lets up to 25 people each run their own install. |
Where Postiz is stronger
Postiz reaches far more places. If you need TikTok, X, Pinterest, Bluesky, Reddit, or Mastodon, Postwright doesn’t post there at all. Postiz also runs in a browser, so a team can work in it from any computer, and posts go out from a server whether or not anyone’s laptop is open.
Postiz Cloud comes with apps each network has already approved. Getting your own approved can take a while – Postiz’s docs say Meta, YouTube, and TikTok can take weeks – and Postwright does ask you to set up your own YouTube and Meta credentials once. Postiz is also open source with a large community: its GitHub repo had 37,347 stars when I checked, and every plan includes an MCP server, a CLI, and an API for AI agents.
Where Postwright is different
Postwright started as the platform behind Step Zero, my own newsletter, so it’s built around one kind of week: a blog post, the email that announces it, and the social posts that share it, treated as one piece of work with an order to it. The blog goes first, because that’s what creates the URL. The newsletter waits until that URL actually answers – Postwright checks it before sending – and the social posts go out carrying the real link. Postiz can publish to WordPress, and its RSS auto-posting can pick up a new blog post once it’s up, but I didn’t find a way to make a newsletter or a social post wait for a blog post to go live.
The newsletter is a whole engine rather than a channel: double opt-in, engagement tiers, and drip sequences written as folders of markdown, with your subscriber list stored in a file on your Mac. And the video engine clips from your own files – a long recording, or a short you shot on your phone – rather than from a YouTube upload, with no per-minute meter.
Postwright runs on your Mac, so your Mac has to be awake for posts to go out on time. If it’s asleep, anything that came due goes out when it wakes, still in order.
What it costs over a year
Postiz Standard is $29 a month: $348 a year billed monthly, or $276 billed yearly, for five channels. Postwright Pro is $199 once, and you pay your AI provider directly for the drafting it does, since you bring your own keys. Self-hosting Postiz costs nothing for the software, but you’re running and maintaining a server with PostgreSQL, Redis, and Temporal on it.
Which one fits
Choose Postiz if
- You post to networks Postwright doesn’t support, like TikTok, X, Pinterest, or Bluesky
- Several people need to work in one shared workspace
- You want a web app, or you don’t use a Mac
- Social posts are the whole job, without a blog or newsletter behind them
Choose Postwright if
- Your week starts with a blog post and a newsletter, and social follows from them
- You want the order enforced by the software, not remembered by you
- You’d rather pay once than pay monthly
- You want video clipped from your own files, on your own machine
Questions
Is Postwright a Postiz alternative?
For someone on a Mac who publishes a blog and a newsletter and wants social and video to follow from them, yes. For a team posting to many social networks from a shared web workspace, Postiz covers more.
Can I self-host Postiz for free instead?
Yes. Postiz is AGPL-3.0, and its docs say a self-hosted install behaves as the top tier with no limits. You run it on your own server with PostgreSQL, Redis, and Temporal, and register your own app with each network. Postwright is a signed Mac installer with a guided setup.
Does Postwright post to TikTok or X?
No. Postwright posts to YouTube, LinkedIn, Facebook Pages, Instagram, and Threads.
The video engine is free with the Step Zero newsletter. Pro adds the blog, the newsletter, social, and the ordering that ties them together, for $199 once, with a 14-day refund.
