Post Bridge vs Buffer (2026): The $99 Unlimited Plan Is Gone, and What Replaced It Is More Honest

Somebody in a Discord told you Post Bridge is "$99 for unlimited accounts". You opened the pricing page today and there is no $99 plan. There is a $49 plan called Pro, a little stepper next to the account count, and a line that says No account limit. Those are not the same promise, and the difference is the whole article.

Post Bridge reshuffled its tiers on 17 September 2026. Buffer has not moved — its own pricing page still reports a last update in November 2025. Everything below was pulled first-hand on 20 September 2026, and anything I could not pull on that date is marked as not fetched rather than guessed.

The plan you were told about is not the plan on the page

Here is what Post Bridge sells today: Starter at $29 for 5 accounts, Creator at $39 for 15, and Pro at $49 with 49 accounts included and $1 for each one after that. Posts are not capped on any of the three. The Pro card carries a quantity stepper, which is the single most predictive thing on any pricing page: when the number of units is something you click up and down inside the card, the tier name is decoration and you are buying a metered good. When there is no stepper, the tier is a real step and you should immediately check whether the top step is tall enough for you.

Buffer has a stepper too, but it drives a different machine. Buffer meters channels on a segmented ladder, and it sells two ladders at once. Essentials is $60 at ten channels, $120 at twenty-five, $195 at fifty. Team is $120, $180 and $255 at the same three points. Work the segments out and the marginal price of the next channel on Essentials is $6, then $4, then $3, then $1 once you pass fifty. On Team it is $12, $4, $3, then $2.

So the two products are not "cheap one and expensive one". They are two shapes. Post Bridge is three flat plateaus followed by a pure $1 meter. Buffer is a staircase that gets gentler the higher you climb and eventually flattens into a meter of its own.

Side by side at six account counts, not at the headline price

A comparison that lists "$29" next to "$6 per channel" tells you nothing, because those two numbers are denominated in different things. The only honest way to line them up is to pick account counts you might actually run and price all three plans at each one.

All figures computed from first-party pricing pages fetched 2026-09-20. Post Bridge Pro above 49 accounts = $49 + $1 each. Buffer segments = $6 / $4 / $3 / $1 (Essentials) and $12 / $4 / $3 / $2 (Team).

The second column every honest comparison owes you is monthly price divided by the published output ceiling. Neither vendor publishes one, so that column is empty for both — and an empty cell is a finding, not a gap. It means your bill scales with logins and not with how hard you work them, which is exactly the opposite of how tools like Later or RecurPost behave.

Past fifty accounts they charge the same dollar, and the gap simply stops moving

This is the part no list article contains, and it falls out of the table above in one line of arithmetic. Above 49 accounts Post Bridge charges $1 for the next account. Above 50 channels Buffer Essentials also charges $1 for the next channel. Two vendors with completely different narratives arrived at the same marginal price.

The consequence is that beyond fifty accounts the difference between the two bills is a constant $145 per month and never changes again. It is an entry fee, not a multiplier. At 50 accounts that $145 is a 290% premium and the choice is obvious. At 1,000 accounts it is 14.5%, and it would be rational to pay it for a feature you actually need. Anyone who ranks these two tools once, at one account count, and calls it a verdict is wrong at one end or the other.

Two pricing pages that look nothing alike can converge on the same marginal price. Compare the price of your next account, not the price on the card.

Buffer Team behaves differently and it matters: its post-fifty rate is $2, so the Team gap does keep growing — $355 against $100 at a hundred accounts, $655 against $250 at two-fifty. If you are on Team purely because you once wanted approvals, that decision is now costing you a multiplier rather than a flat fee. This is the same crossover logic we worked through in SocialPilot vs Buffer, where the answer also flipped at a specific count rather than being true everywhere.

What "unlimited" does not unlimit

"No account limit" is a true statement about a ceiling. It says nothing about the meter, and it says nothing about three other gates that live one level below the pricing page. We have written before about how three different tools use that same word to mean three different things; here is the checklist in its shortest form.

• Per-platform sub-quotas. Blotato's pricing page today sells "20 social accounts" on its $29 Starter, while the machine-readable file on the same domain says "TikTok: 3 accounts x 10 posts a day on Starter". Twenty seats, three of which can be the platform you care about. Nothing on the human-facing page tells you this.
• Daily caps hiding inside an unlimited plan. The Blotato figures above also imply a per-account daily ceiling, and Metricool's page today carries the sentence "Unlimited scheduling may be limited by our Fair Use Policy." Unlimited with a fair-use clause is a number the vendor has chosen not to print.
• What happens at renewal. A meter with no ceiling is a bill with no ceiling. Post Bridge at $1 per account is genuinely cheap, and it is also the plan most likely to surprise you the month you connect eighty accounts because it was easy.

None of that makes Post Bridge the wrong answer. At five accounts the two are within a dollar of each other and you should pick on features. From about ten to fifty accounts Post Bridge is two to four times cheaper per account and it is hard to argue with. Above that, you are choosing whether $145 a month buys you something Buffer has and Post Bridge does not. If you want the same exercise run against the rest of the category, ranking by the price of your next account is the method, and Blotato vs Post Bridge puts a credit-metered tool on the other side of the same question.

There is a third shape worth naming, because neither of these two is it. A desktop engine that signs into your own accounts in a local fingerprint browser has no per-account line item at all — the unit you pay for is the work, not the login. NoobClaw is built that way, which makes it a poor fit if you want a hosted queue and a good fit if the number of accounts is the thing that keeps breaking your budget. Membership pricing is on the website and in the app; the point here is only that "per account" is a pricing choice, not a law of nature.

Frequently asked questions

Is Post Bridge still $99 for unlimited accounts?

Not on the page I fetched on 20 September 2026. The tiers changed on 17 September: Starter $29 for 5, Creator $39 for 15, Pro $49 including 49 accounts with additional accounts at $1 each, and a stepper on the Pro card. The phrase "No account limit" is still there, which is probably why the old $99 number keeps circulating. If you are reading this months later, re-open the page before you quote any of these figures — that is the same rule I applied to write them down.

At how many accounts does Buffer stop being the expensive one?

It never fully does, but it stops being dramatically expensive. Because both vendors charge $1 for each account past fifty, Buffer Essentials stays exactly $145 per month above Post Bridge Pro no matter how far you scale. That premium is 290% at fifty accounts and 14.5% at a thousand. Buffer Team is a different story: its marginal rate is $2, so the gap widens indefinitely.

Do either of them cap how many posts I can publish?

Neither publishes a post cap on its pricing page as of 20 September 2026, which is why that column is blank in the table above rather than filled with a guess. Be aware that "no published cap" and "no cap" are different claims — a fair-use policy can exist without a number attached to it, and the platforms themselves impose per-account daily limits that no scheduler can lift. If a vendor quotes you an unlimited plan, ask them in writing what the per-platform daily ceiling is before you plan a matrix around it.
