Sendible vs Buffer (2026): One Sells Seats for Free, the Other Sells Channels One at a Time

Sixty accounts, two posts each, every day. That is 120 publishing actions daily — a number that sounds unremarkable until you notice that Sendible's entry plan allows 100 sends per day, and that its account count column never hints at this. Meanwhile Buffer would happily publish all 120, and bill you for sixty channels.

That is the whole of Sendible vs Buffer in one scenario: one rations throughput, the other rations connections. Both were read on 2026-09-17.

Buffer, priced per channel — including the ladder they publish for machines

Source: buffer.com/pricing and its machine-readable twin at buffer.com/pricing.md, both 2026-09-17.

The volume ladder used to be something you could only find on third-party blogs. Today Buffer publishes it itself, on a page written for AI agents: Essentials $6 per channel for channels 1-10, $4 for 11-25, $3 for 26-50, $1 for 51+; Team $12, then $4, $3, $2. Their own worked examples: 25 channels is $120 a month, 50 channels is $195.

Apply that to our sixty accounts and Essentials monthly comes to $205 (ten at $6, fifteen at $4, twenty-five at $3, ten at $1), or roughly $171 a month on yearly billing, which saves about two months. That is a real number you can compute before signing up — a rarity in this category.

Buffer also defines its "unlimited". From today's FAQ: unlimited scheduling is subject to a fair use policy capping usage at 5,000 posts per channel, which they justify by saying nobody has ever exceeded it. Two posts a day on one channel would take about seven years to get there, so for most people it is honest. It is still the second ceiling, and second ceilings are where comparisons go wrong.

Every vendor has a second ceiling. Buffer prints theirs, in a sentence, on the page you were already reading.

Sendible, priced per workspace — with the prices still missing

Source: sendible.com/pricing, 2026-09-17. The structure renders; the money does not. In the page's static markup, every plan shows a dollar sign, a slash, "mo", and nothing in between: the amounts are drawn in only after you pick a currency (USD, GBP or EUR) and a billing period in a live browser.

There is a trap here we have walked into before and now check for by default. The tempting sequence on that page is 1 / 3 / 7 / 15 / 50, and it reads exactly like a price ladder. It is the workspace count. Any extractor that reports those as dollars has shifted a column — and the resulting curve looks so plausible that the error never announces itself. Rule of thumb worth stealing: if your scraped price column is cell-for-cell identical to another column of quotas, it is a parsing misalignment, not a bargain.

What is verifiable today:

Three structural facts fall out of that table. Profiles are always workspaces times six — you cannot buy profiles, only workspaces that arrive with six each. Users are unlimited on every plan; the page's own title sells it as zero per-seat taxes. And the daily send limit stops growing after Elite: Enterprise buys you more workspaces and more profiles, not more throughput. Yearly billing is marked as saving 15%, with a 14-day trial and no card required.

Which ceiling do you hit first?

Put your own numbers into three questions and the answer usually appears immediately.

1. How many humans need access? On Buffer, Essentials includes exactly one user; team access means Team at double the per-channel rate. On Sendible, seats are free at every tier. For an agency with freelancers and clients, that difference alone can outweigh everything else.
2. How many publishing actions per day? Buffer does not meter this (short of 5,000 posts per channel). Sendible meters it per workspace, and the limit is deliberate — the page explains it exists to comply with social network guidelines. Sixty accounts posting twice daily needs 120 sends; on Sendible those accounts also need ten workspaces just to hold 60 profiles, which puts you at Elite.
3. Are your accounts clients, or are they yours? Sendible's entire model assumes clients: workspaces, approvals, branded reports, client connect. Buffer assumes channels in one queue.

When Sendible is the better pick: you run social for several clients, you need approval workflows and white-labelled reporting, you want stakeholders and freelancers in the tool without paying per head, and no single client publishes more than a few times a day. That is a real and common shape, and Buffer handles it clumsily.

When Buffer is the better pick: you are one to three people, your accounts are your own, you want a price you can calculate in advance, and you would rather pay $1 for the fifty-first channel than jump a plan. Its API quota table (3,000 / 7,500 / 15,000 requests per month) is also published per tier, which matters if an agent drives your queue.

Neither, incidentally, produces the content. If sixty accounts need sixty different captions and a pace that does not look like one operator, that work happens before the scheduler — which is where something like NoobClaw fits, publishing from local browser sessions under your own logins with per-account personas rather than through platform APIs.

FAQ

How much does Sendible cost?

We are not going to guess. On 2026-09-17 the pricing page rendered plan names, workspaces, profiles, user counts and daily send limits, but the price fields were empty in the page source — amounts are drawn after you select currency and billing period in a browser. Yearly billing is advertised at 15% off. Check the live page, and ignore any figure that matches the 1 / 3 / 7 / 15 / 50 workspace sequence.

Is Buffer's unlimited posting really unlimited?

No, and Buffer says so: scheduling on paid plans is subject to a fair use policy capping 5,000 posts per channel. Free plans are capped differently and more tightly — 10 scheduled posts per channel at a time, with slots freeing up as posts publish.

Which is cheaper for 20 social accounts?

On Buffer you can calculate it: Essentials monthly is ten channels at $6 plus ten at $4, so $100 a month ($83 or so on yearly billing); Team doubles the first ten. On Sendible, 20 profiles means four workspaces, which lands on the Premium tier (7 workspaces, 42 profiles) — but since the amounts do not render publicly, the comparison has to end at structure. What you get for it differs too: unlimited seats and a 300-sends-per-day ceiling.
