The Postiz vs Buffer decision comes down to one question: do you want a scheduler that bills per channel forever, or one you own outright and maintain yourself.
You have a calendar to fill and two obvious ways to fill it. One is polished, hosted, and charges by the account. The other is free, open source, and asks you to run Postgres, Redis, and Temporal before you write a single post.
That framing makes the choice sound easy, and it is not. Plenty of people who could self-host still pay Buffer, because the bill is smaller than the Saturday.
This guide runs the same workflow through both, prices out what each actually costs at three, ten, and thirty channels, and gives you a decision table you can act on.
Table of Contents
TL;DR: Key Takeaways
- In postiz vs buffer, Postiz optimizes for ownership and Buffer optimizes for zero operations. That sentence predicts almost every difference below.
- Buffer charges per channel per month. Essentials is $5 per channel, Team is $10 per channel, and the bill scales with your account count.
- Self-hosted Postiz has no channel limit at all. You pay for a server, not for accounts.
- Buffer’s free plan is real but small: 3 channels, 10 scheduled posts per channel, one user.
- Postiz includes AI drafting, images, and short video in the same open source build.
- Buffer requires no server; Postiz requires a real one. Postgres, Redis, and Temporal are not optional.
- The crossover is around five channels. Below that Buffer usually wins on total cost; above it, Postiz pulls ahead fast.

What Is Postiz?
Postiz is an open source social media scheduling tool you run on your own server. It connects to more than 30 networks, holds one shared calendar, customizes copy per platform, and reports analytics per channel and per post.
It is licensed AGPL-3.0, written in TypeScript, and sits at roughly 34,700 stars on the project’s GitHub repository, where it describes itself as an open source alternative to Buffer and Hypefury.
There is a paid cloud version at $29 to $99 per month by channel count, and it runs the same code you can deploy yourself. Our full explainer on Postiz covers its features in depth.
The common misconception
People assume the free self-hosted build is a stripped-down edition. It is not. AI drafting, image and short-video generation, analytics, team roles, the Public API, and webhooks are all in the same open source code.
What self-hosting costs you is not features. It is the Postgres, Redis, and Temporal stack underneath, plus a developer app for every network you connect.
What Is Buffer?
Buffer is one of the longest-running hosted social schedulers, and it has settled on a pricing model that is unusually easy to reason about: you pay per connected channel per month.
The free plan gives you 3 channels, 10 scheduled posts per channel that refill as they publish, 100 ideas, a single user, 30 days of analytics, and one API key with 3,000 requests a month.
Essentials is $5 per channel per month, or $60 a year, and removes the post cap while adding advanced analytics, a hashtag manager, first comment scheduling, channel groups, and 3 API keys with 7,500 requests.
Team is $10 per channel per month, or $120 a year, adding unlimited team members, approval workflows, custom access controls, branded reports, and 5 API keys with 15,000 requests. Buffer applies a volume discount above ten channels.
The pricing shape that decides this comparison
Buffer’s cost is linear in channels. Three channels on Team is $30 a month. Thirty channels is $300 a month before the volume discount.
Postiz’s cost is flat. A server is a server whether it holds three accounts or fifty. That single difference in shape, not any feature, is what settles most postiz vs buffer decisions.
Postiz vs Buffer: 6 Key Differences That Matter
Feature-by-feature lists mostly produce ties. These six are where the choice is genuinely made.
1. How the bill scales
This is the sharpest dividing line.
Everything else in postiz vs buffer follows from this. Buffer’s per-channel model is honest and predictable, and it is also the thing that pushes agencies away. Every client you onboard adds a recurring line item, and the ones with six networks each add six.
Postiz self-hosted has no channel fee. Whether that is cheaper depends entirely on how many accounts you run, which the cost tables below settle with numbers.
Rule of thumb: under five channels, Buffer is usually cheaper once you count your time. Over ten, it rarely is.
2. Who runs the infrastructure
Here Buffer wins on merit, and it is not close.
Buffer is a URL. You sign up, connect accounts through their approved integrations, and publish. There is no database, no certificate, no queue worker.
Postiz needs a real server running PostgreSQL 14 or later, Redis 6 or later, and Temporal, which has been required since version 2.12.0. Its docs are also explicit that it sets secure cookies and expects HTTPS in production, so a reverse proxy is part of the install.
This gap is the strongest argument for either Buffer or managed Postiz hosting.
3. Connecting the accounts
Buffer handles platform relationships for you. You click connect and authorize.
On self-hosted Postiz you create a developer app per network, with your own credentials and redirect URLs, and some platforms take days to approve. This is the step that stalls more Postiz installs than any technical failure.
It is also a one-time cost that buys you independence from anyone else’s API quota.
4. AI and content generation
Postiz ships an agent that drafts posts, generates images, and produces short videos, and connects to external models including Claude and ChatGPT. Self-hosted, you bring your own model keys and pay providers directly.
Buffer’s AI is narrower in scope, oriented around reply suggestions and assistance rather than media generation, and the free tier caps it at five suggestions a week.
If AI-generated media is central to your workflow, this difference is decisive.
5. Automation and API limits
Both expose APIs. The limits differ in kind.
Buffer meters API requests by tier: 3,000 a month on free, 7,500 on Essentials, 15,000 on Team. Postiz applies a rate limit of 90 requests an hour on the create-post endpoint, 100 on cloud, and self-hosted instances can raise it with the API_LIMIT environment variable.
Postiz also ships a dedicated n8n node plus Make.com and Zapier integrations, which matters if you already run automation. If you are choosing an automation layer too, our n8n vs Zapier comparison is the companion read, and the Postiz n8n guide builds the pipeline.
6. Portability and lock-in
Lock-in is the quietest factor in postiz vs buffer.
Postiz keeps your posts, media, and tokens in a database you control. Move the volume and the dump to another host and you have moved, and nothing external has to agree.
Buffer holds your content and history in its cloud. Exports exist, but your scheduling history and analytics are theirs, and a pricing change leaves you paying, exporting, or rebuilding.
That asymmetry is the whole argument for open source, stated plainly.
Postiz vs Buffer: The Same Workflow in Both Tools
A concrete comparison beats a feature grid. Here is one week of content for a brand on LinkedIn, X, and Instagram, run through each.
| Step | Postiz | Buffer |
|---|---|---|
| Connect 3 channels | Create 3 developer apps, then authorize | Click connect, authorize |
| Draft 5 posts | One composer, per-network variants | One composer, per-network variants |
| Attach images | Upload to your own volume or R2 | Upload to Buffer |
| Generate a variant with AI | Built in, your model key | Assistance, narrower scope |
| Schedule across the week | Shared calendar | Queue plus calendar |
| Route through approval | Admin and member roles | Team tier only |
| Read results | Per channel and per post | Advanced analytics on paid tiers |
| Monthly cost at this size | Server only | $15 on Essentials, $30 on Team |
At three channels, Buffer is genuinely the easier answer. The picture inverts as the channel count climbs.
Postiz vs Buffer Cost at 3, 10 and 30 Channels
The postiz vs buffer cost question is arithmetic, not opinion. Postiz figures assume a managed server, since a fair comparison should include hosting rather than pretending self-hosting is free.
| Channels | Buffer Essentials | Buffer Team | Postiz self-hosted |
|---|---|---|---|
| 3 | $15/month | $30/month | Server cost only |
| 10 | $50/month | $100/month | Server cost only |
| 30 | $150/month | $300/month | Server cost only |
| Over 3 years at 10 channels | About $1,800 | About $3,600 | About 36 months of one server |
Buffer applies a volume discount above ten channels, so the 30-channel figures are an upper bound rather than a quote.
The software line favors Postiz clearly at scale. The time line favors Buffer at every scale. Which column is larger depends on what your hours are worth and whether anyone on the team enjoys this work.
Postiz vs Buffer Use-Case Mapping {#mapping}
| Your situation | Better fit | Why |
|---|---|---|
| Solo creator, 2 to 3 accounts | Buffer | The free tier may cover you entirely |
| Small brand, 5 accounts, no ops appetite | Buffer | $25 a month beats a weekend |
| Agency with 10+ client channels | Postiz | Per-channel billing is the problem you are solving |
| Team that needs draft-then-approve | Either | Postiz roles are free; Buffer needs the Team tier |
| Heavy AI media generation | Postiz | Image and short-video generation are built in |
| Publishing driven by automation | Postiz | Dedicated n8n node and an adjustable API limit |
| Strict data residency requirements | Postiz | Content and tokens stay in your database |
| Nobody available to run a server | Buffer | Or managed Postiz hosting, which removes the same objection |
Postiz vs Buffer: Which Should You Choose? {#choose}
Two checklists settle most postiz vs buffer decisions. Whichever one you nod along to more is your answer.
Choose Postiz if…
- ✅ Your channel count is growing and per-channel billing already annoys you
- ✅ You want your content, media, and tokens in a database you control
- ✅ AI drafting and generated media are part of the workflow
- ✅ You publish from automation and want a real API without a monthly request quota
- ✅ You can run a server, or you will pay a host to run it for you
If that describes you, the ceiling on Postiz is your willingness to maintain it, not the software.
Choose Buffer if…
- ✅ You run a handful of channels and expect that to stay true
- ✅ Nobody on the team wants to think about Postgres, Redis, or certificates
- ✅ The free tier or a $15 monthly bill is genuinely cheaper than your time
- ✅ You want platform relationships handled for you, with no developer apps to create
- ✅ Predictable billing matters more than flat billing
If that describes you, price it honestly at your actual channel count before deciding.
Where to Host Postiz
If the comparison points at Postiz, the next question is where it runs. It needs a real server, not shared hosting, because the stack runs several long-lived services. This comparison of shared, VPS, and cloud hosting covers the distinction.
Run it yourself when you already operate servers and an evening of docker-compose is not a cost for you. The Postiz self-hosting guide walks the whole path.
Run it on managed hosting when you want it live on a real domain today and would rather the database and workflow layer be somebody else’s pager. That is the self-managed versus managed decision in one line.
xCloud Postiz Hosting takes the second path. Postiz v2.23.0 deploys with PostgreSQL, Redis, Temporal, and Elasticsearch already wired, managed HTTPS with a free SSL certificate, six persistent volumes covering configuration and uploads, and automatic backups running. Dependencies stay on the private network rather than exposed publicly.
| Plan | Price | Specs |
|---|---|---|
| Cloud VPS 6 GB | $24.99/month | 6 GB RAM, 4 vCPU, 100 GB SSD, 30 TB bandwidth |
| Cloud VPS 16 GB | $59.99/month | 16 GB RAM, 6 vCPU, 200 GB SSD, 30 TB bandwidth |
| Cloud VPS 24 GB | $84.99/month | 24 GB RAM, 8 vCPU, 300 GB SSD, 30 TB bandwidth |
Worth being clear about what you are buying. A Buffer subscription is access priced per account. A plan here is an actual server, and that difference shows up in what you can do with it:
- ✅ No channel limit, so onboarding a client adds work but not a line item
- ✅ Unlimited team members with roles, at no extra cost per seat
- ✅ Your content, media, and access tokens in a database you control
- ✅ HTTPS, backups, and the Postgres and Temporal layer configured on day one

Pick One This Month and Stop Comparing
The gap in postiz vs buffer is not really about features. Both hold a calendar, both customize per network, both report on what happened, both let a team work together.
The gap is about the shape of the bill and who runs the servers. Buffer charges per account and asks nothing of you operationally. Postiz charges nothing per account and asks for a server plus an OAuth app per network.
So do the cheap arithmetic. Count the channels you will run twelve months from now, not today, and multiply by $5 and $10. If that number is comfortably under what a server plus an hour a month costs you, stay on Buffer and stop reading comparisons.
If it is not, spend one weekend standing Postiz up and building your first content calendar. That decision, more than the software choice, is what you will be living with in three years.

Frequently Asked Questions {#faq}
Is Postiz better than Buffer?
Neither is better in general. In the postiz vs buffer trade-off, Postiz wins on cost at scale, data ownership, and AI media generation, while Buffer wins on setup simplicity and zero operational load. Pick based on your channel count and whether anyone will run a server.
Is Postiz free?
The self-hosted build is free under AGPL-3.0, with no channel limit and no seat gate. You pay only for the server. The managed cloud version at postiz.com runs $29 to $99 per month depending on how many channels you connect.
How much does Buffer cost per channel?
Essentials is $5 per channel per month, or $60 per year. Team is $10 per channel per month, or $120 per year, and adds unlimited team members, approval workflows, and branded reports. Buffer applies a volume discount beyond ten channels.
Does Buffer have a free plan?
Yes. The free plan covers 3 channels, 10 scheduled posts per channel that refill as they publish, 100 ideas, a single user, 30 days of analytics history, and one API key with 3,000 requests a month. For a solo creator on a few accounts, it is often enough.
At what channel count does Postiz become cheaper?
Roughly five, once you include a managed server in the comparison. Below that, Buffer’s per-channel bill is smaller than hosting plus your time. Above ten channels the gap widens quickly, because Postiz cost is flat while Buffer cost is linear.
Can I move from Buffer to Postiz without losing my calendar?
You can move forward but not backward cleanly. Buffer exports let you retrieve content, and you re-authorize each network in Postiz through its own developer app. Scheduling history and Buffer analytics do not transfer, so plan the switch at a natural break.
What are the main Postiz alternatives besides Buffer?
Hypefury and Later occupy similar commercial ground, and Mixpost is the closest open source comparison. For most teams the real choice is between a hosted per-channel subscription and a self-hosted flat-cost tool, which is exactly the postiz vs buffer question.
Does Buffer or Postiz have better analytics?
Buffer’s advanced analytics on paid tiers are more polished and include branded reports. Postiz returns impressions, engagement rate, and reach per channel and per post, which covers what most teams act on. In postiz vs buffer terms, Buffer wins on presentation and Postiz wins on not charging extra for it.
Does Postiz have API rate limits?
Yes, but they work differently from Buffer’s. Postiz limits the create-post endpoint to 90 requests an hour, 100 on cloud, rather than metering total monthly requests. Self-hosted instances can raise that with the API_LIMIT environment variable.
