Short answer: Postiz is an open-source social media scheduler you host yourself; Buffer and Hootsuite are hosted tools that bill per channel or per seat. Postiz schedules and queues posts across the same networks, keeps your accounts and drafts on your own server, and doesn’t charge more as you add channels. Buffer is faster to set up and hands-off. I run Postiz on my own infrastructure, and here’s the comparison.
Scheduling social posts is the kind of small recurring job that quietly gets metered per channel until the bill adds up. I moved that job onto Postiz, self-hosted. Here’s how it stacks up against the default.
Side by side
| Dimension | Postiz (self-hosted) | Buffer / Hootsuite |
|---|---|---|
| Source | Open (AGPL-3.0) | Closed |
| Where accounts & drafts live | My server, in the EU | Their cloud |
| Pricing model | Flat — the server it runs on | Per channel (Buffer) / per seat (Hootsuite) |
| Channels | Add as many as you want | Each one adds to the bill |
| AI drafting | Built in, on your own API key | Bundled, on their terms |
| Setup | Docker stack, you run it | Sign up, connect, done |
| Best for | Ownership, many channels, flat cost | Fast start, zero maintenance |
What they share
All three do the core job: connect your social accounts, write posts, schedule them to a queue, publish across networks, and show basic analytics on what went out. For “line up a week of posts and let them go,” they’re comparable.
Where they differ
The pricing model. Buffer charges per connected channel; Hootsuite charges per seat on higher tiers. Both mean cost scales with how much you use them: more accounts or more people, bigger bill. Postiz costs the server it runs on, flat, whether you connect three channels or thirty.
Who holds your accounts. With a hosted tool, your connected social accounts, drafts, and queue live on their platform. With Postiz, the connections and content sit in a database on infrastructure I control. Nothing about your posting pipeline depends on a vendor’s continued goodwill or pricing.
AI on whose key. Postiz has built-in AI drafting that runs on an API key you provide, so the generation goes to a provider you chose. Hosted tools bundle AI on their own terms and their own model. Small difference day to day, real difference on who sees your drafts.
The honest cost. Buffer and Hootsuite win on zero setup and zero maintenance. Postiz is open-source software you have to run: a Docker stack, backups, updates, and reconnecting accounts when tokens expire. That’s ongoing work a hosted tool absorbs.
Which should you pick?
- Stay on Buffer or Hootsuite if you want zero infrastructure, you manage a handful of channels, and the per-channel or per-seat cost is fine at your size.
- Switch to Postiz if you’re running many channels and the per-channel bill has become a tax, or you want your accounts, drafts, and content on infrastructure you own.
The recurring catch across everything I self-host: the tool is the easy part; running it well is Docker, backups, and maintenance. That gap is the theme of the self-hosted stack I run instead of paying for SaaS.
If you want owned automation like this — social scheduling and the rest — built and handed to your team, that’s the kind of thing I do at Leinss Consulting.
