n8n Social Media Posting Without Blotato: Who Pays for the Last Step, and In Which Unit
- The n8n node is free. The bill sits in the publishing vendor’s account unit, and swapping vendors is the only lever that moves it.
- Blotato meters two things at once: credits, which you can top up at $6.00 per 1,000, and connected accounts, which are not for sale at any price.
- At 40 accounts the posting step costs $49 on Post Bridge, $97 on Blotato, $99 on Postiz, $138 on Zernio, $165 on Buffer — but the 41st account costs $0 to $402.
- n8n’s own plan pricing was not re-fetched today, so it is deliberately absent from the table.
Your workflow works. The trigger fires, the script gets written, the render finishes, the asset lands in storage, and then one node at the end pushes it out to every account you own. That last node took ten minutes to configure and it is doing the least interesting work in the whole graph. It is also, almost certainly, the only part of the workflow you are paying a subscription for.
That is a strange feeling once you notice it, and it explains a search pattern that shows up from both directions at once. From one side: n8n social media automation, n8n social media automation template, n8n social media posting automation, n8n social media manager. From the other: blotato n8n node, blotato community node, blotato api n8n, blotato vs n8n. Same people, circling the same joint. The orchestration is free and the last inch is metered.
This piece is only about that last inch — who charges for it, in which unit, and what happens when you outgrow the unit. We have written elsewhere about where the publishing step actually breaks and about why the workflow is the easy half of a template, so none of that is repeated here.
The node is free. You are paying two meters behind it.
Here is the thing that catches builders out, and it catches them late. Routing through Blotato means two separate limits apply to you, and only one of them behaves like a limit.
The first is credits. Blotato's plans carry 1,250, 5,000 and 28,000 AI credits per month, and extra packs are published at $6.00 for 1,000. Credits are visible: when you run low, calls fail, you see it in an execution log, and you can buy your way out the same afternoon. Whether they roll over is genuinely unclear — the vendor's own machine-readable pricing file states that credits roll over month to month, and we could not find a first-hand statement of a monthly reset anywhere in today's fetch. Treat that as an open question rather than a fact you have been told.
The second is the connected account count: 20 on Starter, 40 on Creator, 100 on Agency. This one does not fail loudly. It simply declines to let you connect the forty-first account. There is no dropdown on the card and no quantity slider, and searching the add-on list for "accounts" returns nothing — the vendor sells credits and does not sell reach. What you can buy is a quote; what you cannot buy is a spec. Twenty, forty and a hundred are specs.
A credit meter interrupts you and can be topped up. An account ceiling does not interrupt you — it just quietly decides how big your operation is allowed to get, and no amount of money in your n8n budget touches it.
What the last node costs at forty accounts
Forty is a useful place to stand because it is where a serious multi-account operation usually sits and it lands awkwardly in almost every vendor's tier structure. Every number below was re-fetched from the vendor's own page on 19 September 2026.
| Vendor | Plan you land on at 40 accounts | Monthly price | Price ÷ account | Marginal cost of the 41st account |
|---|---|---|---|---|
| Post Bridge | Pro (49 accounts included) | $49 | $1.23 | $0 up to 49, then $1.00 each via a quantity selector |
| Blotato | Creator (40 accounts) | $97 | $2.43 | $402 — the only route past 40 is the $499 tier |
| Postiz | Ultimate (100 channels) | $99 | $2.48 | $0 inside the plan, all the way to 100 |
| Zernio | Usage-billed (2 free, then per band) | $138 (8×$6 + 30×$3) | $3.45 | $3.00 |
| Buffer | Essentials (progressive per channel) | $165 (10×$6 + 15×$4 + 15×$3) | $4.13 | $3.00 |
Column-equality check before anything else: the price column reads $49 / $97 / $99 / $138 / $165 and matches no account column cell for cell, so this is a price table rather than a misparsed quota table. Good.
Now read the last column, because it is the one your workflow will run into and the one no comparison post prints. The averages in column four span a factor of three and a half, which is interesting but not decisive. The marginal column spans from zero to four hundred and two dollars for the identical action. Adding your forty-first account is free on Postiz, costs a dollar on Post Bridge, costs three dollars on Buffer and Zernio, and costs $402 on Blotato — not because Blotato is expensive per account, but because there is no such thing as buying one account there. You buy a tier or you stop.
That is the specific reason a lot of n8n builders end up searching for a way out. Their workflow scaled smoothly from five accounts to forty. It cannot scale smoothly from forty to forty-one.
The scarcity question your workflow cannot answer for you
Before you pick a replacement, it is worth asking where each vendor has put the scarcity — on the people, or on the content. A tool that meters seats assumes your output volume is fixed and your headcount is the expensive thing; that shape suits an agency running campaigns for clients. A tool that meters accounts, channels or posts assumes people are cheap to add and distribution is the scarce good; that shape is the one an automation builder needs, and it is also the one that will cap you hardest.
Every vendor in the table above meters on the content side, which is why they are all plausible replacements for each other — and why none of them fixes the underlying issue by itself. The thing you are actually buying with that subscription is a connection to each platform: an approved app, a maintained set of credentials, and someone else's problem when a platform changes its flow. That is a real service and it is reasonable to pay for it.
It is worth being honest about what the other direction costs, though. The alternative to renting someone's connections is holding them yourself — either through your own approved platform apps, or by having each account sign in through its own local browser profile the way a person would. That is the shape of our own approach: accounts log in locally, credentials never leave the machine, each account's content is generated separately from its own brief, and human review stays in the loop before anything goes out. It removes the per-account subscription meter and replaces it with setup work and your own judgement about pacing. Neither of those is free either. The useful framing is not "which is cheaper" but which cost do you want to be carrying at a hundred accounts — a bill that grows with every account, or an operation you have to run yourself.
What we could not verify today
n8n's own plan prices were not re-fetched on today's pass, so there is deliberately no n8n row in the table. Self-hosted n8n is free to run and costs you a server; the cloud tiers are metered on executions, and an execution count is a completely different unit from an account count, so mixing them into one table would produce a comparison that looks precise and is not. If your workflow fires once a day per account, executions are unlikely to be your binding constraint — but check the current numbers yourself rather than taking that from here.
Published API request ceilings are similarly thin. Buffer is the only vendor in this group that states them: 100 requests per 15 minutes on every tier, 3,000 / 7,500 / 15,000 per 30 days by plan, with 429 responses carrying a Retry-After header and not consuming quota. Postiz, Post Bridge and Blotato publish no request ceilings today. That is not evidence they have none, and for a workflow that bursts, an unpublished ceiling is a risk you should price rather than ignore.
FAQ
Can I post to social platforms from n8n without any paid publishing tool?
Technically yes, by registering your own developer app with each platform and calling their APIs directly from HTTP nodes. What you are trading is a monthly fee for an approval queue: several major platforms require submissions, a privacy policy and terms of service, and at least one vendor states publicly that those reviews usually take more than a month. That is the real reason most builders rent connections instead.
Does swapping the publishing vendor mean rebuilding my workflow?
Rarely more than the final node. Every vendor here accepts roughly the same call — an asset plus a list of destinations plus a schedule — so the expensive parts of your graph, the sourcing and generation and approval logic, carry over intact. That portability is exactly what makes the account ceiling worth optimising: it is the one part of the stack you cannot refactor around.
Is the Blotato n8n node itself an extra cost?
No, the node is free and so is installing it. The cost is entirely on the account behind it, in credits and in the connected-account ceiling. We have compared the two as products elsewhere and the short version holds: they charge for completely different things and most people genuinely should use both. The question this article asks is narrower — whether the account unit is the right one to be renting at your scale.
One thing to do before your next build
Open your workflow and find the last node. Write down two numbers next to it: how many accounts you are connected to today, and how many you expect in six months. Then go and find the marginal cost of that future account on your current vendor — not the average, the marginal. If the answer is a dollar, carry on. If the answer is the difference between two tiers, you now know the exact month your automation stops scaling, and you have time to move the last node before you get there. The same audit applies to any pipeline built on this pattern — the generation half is elastic, the distribution half is not.
