Postiz Self-Hosted: What "Free" Actually Costs You in 2026
- The license is genuinely free (AGPL-3.0) and Postiz says the self-hosted build has no feature gap versus the hosted one. That part is not the catch.
- The catch is that you supply your own platform API credentials — Meta app review, TikTok developer audit, X API pricing — and each of those is a separate approval process.
- Ongoing cost is a small VPS plus your time when a platform changes something. Budget maintenance hours, not just setup hours.
- Self-hosting is the right call when you have many channels, an existing server, and a tolerance for OAuth debugging. Otherwise the $29/mo cloud tier is cheaper than your weekend.
"It is open source, so it is free" is true about the license and misleading about everything else. Let me lay out the actual bill, because the parts that cost you are not the parts you are expecting.
What is genuinely free (this part is real)
Postiz is released under AGPL-3.0, the repository is active with roughly 35.3k stars, and — this is the unusually generous bit — the project's documentation states that there is currently no difference between the hosted version and the self-hosted version. No crippled community edition, no "Instagram is a paid add-on."
That is a genuinely better deal than several competitors. Mixpost's free Lite edition, for comparison, only supports Facebook Pages, X and Mastodon; everything else needs the $299 Pro license. We put those side by side in Postiz vs Mixpost.
The software being free is real. The capability being free is a different claim, and nobody makes that one out loud.
Bill item 1: the server (small, predictable)
Postiz deploys to the usual suspects — a VPS, Railway, Hetzner, Coolify, or any cloud. It needs a database and a worker process, so the very smallest instances are tight but a modest VPS is enough for a personal deployment. Call this a small fixed monthly cost that is easy to reason about.
This is the item people budget for, and it is the one that matters least.
Bill item 2: platform developer approvals (large, unpredictable)
This is the real bill, and it is the one that surprises people on day two.
When you use a hosted service, you are borrowing their approved developer apps. When you self-host, you register your own and go through each platform's review. Depending on the networks you need:
- Instagram / Facebook: Meta Graph API, app review for publishing permissions, business verification, and the target accounts generally need to be Professional accounts connected appropriately.
- TikTok: a developer application plus an audit before content posting is allowed on real accounts.
- X: API tiers have been repriced repeatedly; the free tier is very thin for posting workloads.
- LinkedIn: partner program access for some publishing scopes.
None of these are Postiz's doing. But the honest summary is: the software installs in an afternoon; the integrations can take weeks and some may not be approved at all for a solo operator. ⚠️ Every one of these programs changes its requirements — check each platform's current developer docs rather than any tutorial.
Bill item 3: maintenance (small each time, endless)
Platforms change things. When they do, someone pulls the fix and redeploys. On a hosted plan that person is an employee of the vendor; self-hosted, it is you, usually at an inconvenient time. The project being active is good news here — fixes exist — but applying them is still work.
The decision, in one table
| Self-host if… | Pay for hosted if… |
|---|---|
| You already run a VPS and are comfortable with Docker and OAuth | Your first reaction to "OAuth redirect URI mismatch" is dread |
| You need many channels — the $99/mo tier covers 100, but self-host is unlimited | You have fewer than 10 channels; $29/mo is less than your setup time |
| Data residency or privacy requirements rule out third-party hosting | You want platform integrations that someone else keeps working |
| You are building it into a larger automation stack | You want to be publishing this week, not this quarter |
One thing self-hosting will not buy you
A scheduler — hosted or self-hosted — moves finished posts. It does not make eight accounts say eight different things, and it publishes through APIs rather than behaving like a person using the app.
If your actual problem is "I have accounts and not enough distinct content for them," that is a different tool category. NoobClaw is a desktop app that runs locally: your accounts are logged in by you in isolated fingerprint browser profiles (no passwords handed over), and each one generates its own content from its own niche and persona, on randomized timing. It is not an alternative to Postiz so much as the step before it. Background in open source social media automation tools.
FAQ
Is self-hosted Postiz missing features?
Per the project's documentation, there is currently no feature difference between hosted and self-hosted. What differs is who supplies the platform API credentials and who does upgrades.
What does Postiz cost if I do not self-host?
$29/mo for 5 channels, $39 for 10, $49 for 30, $99 for 100, with a 7-day trial (verified 2026-08-30 — check the current page).
Can I self-host and still post to Instagram and TikTok?
Yes, if you obtain and maintain your own approved developer credentials for those platforms. That approval, not the software, is the hard part.
The one thing to do today
Before you provision anything, open the developer portal for the single most important platform on your list and read its approval requirements for content publishing. If you would not survive that review, the rest of the self-hosting plan is moot — and you have saved yourself a weekend.
