Mixpost vs Buffer (2026): $299 Once vs a Per-Channel Bill — the Break-Even Month, and the Costs Left Off the Page
- Mixpost Pro is $299 once (1 domain, 1 year of updates, unlimited accounts and users). Buffer Essentials is $6 per channel per month for the first ten channels, then cheaper per channel as you grow.
- Break-even vs Buffer monthly: about 10 months at 5 channels, 5 at 10, 2.5 at 25, 1.5 at 50. At 3 channels it takes longer than the one update year included.
- Mixpost Lite is free but only connects Facebook Pages, Mastodon and X. If you need Instagram, TikTok or LinkedIn, the real choice is Pro vs Buffer.
- Mixpost admits platforms impose rate limits and may charge to raise them. That, your server and your own developer apps are what the $299 does not cover.
Subscription fatigue has a very specific moment: the card statement where the scheduler line has quietly grown because you added four more channels. That is usually when someone types "mixpost vs buffer". Mixpost's offer, $299 once and unlimited everything, reads like the way out.
It can be. But the two products put their costs in different places, and the one-time price is only honest if you also price what moved onto your side of the table. This comparison uses both vendors' pages as of 2026-09-23 and works out the break-even month for your channel count, then lists the costs Mixpost's own FAQ admits to.
Two ways to pay: rent per channel, or buy once per domain
Buffer charges per connected channel, one social account each, on a progressive ladder. On Essentials the first ten channels are $6 each per month, channels 11 to 25 are $4, 26 to 50 are $3, and anything beyond is $1. The vendor's worked example puts 10 channels at $60 a month ($50 on annual billing) and 50 channels at $195 ($163 annual). Essentials is one user. Team, with unlimited users, charges $12 for the first ten channels and then the same bands.
Mixpost does not meter usage at all. Lite is free and open source but connects only Facebook Pages, Mastodon and X. Pro is $299 once for one domain or subdomain, with a year of updates. Enterprise is $1,199 once and adds white-labelling and client billing. Both paid tiers advertise unlimited social accounts and "No per-seat pricing". The renewal price for updates after the first year is not published; the page only calls renewal optional.
| Plan | Price | Unit · included | $ ÷ accounts | Second limit | $ ÷ post cap | Seats |
|---|---|---|---|---|---|---|
| Mixpost Lite | free | 1 install · Facebook Pages, Mastodon, X only | not applicable | platform rate limits | — | not per-seat |
| Mixpost Pro | $299 once | 1 domain · unlimited accounts · 1 year updates | not applicable (unlimited); use break-even months | platform rate limits | — | not per-seat |
| Mixpost Enterprise | $1,199 once | 1 domain · white-label, client billing | not applicable | platform rate limits | — | not per-seat |
| Buffer Essentials, 10 channels | $60/mo ($50 annual) | channel | $6.00 (next one $4) | fair use 5,000 posts per channel, no period stated | not computed (no period) | 1 |
| Buffer Essentials, 50 channels | $195/mo ($163 annual) | channel | $3.90 (next one $1) | same | — | 1 |
| Buffer Team, 50 channels | $255/mo ($213 annual) | channel | $5.10 (next one $2) | same | — | unlimited |

Putting Mixpost into a "price per account" column would be a mistake. With unlimited accounts the denominator is infinite, and the column would say it is free, which it is not. The honest unit for a one-time license is months to break even.
The break-even month, by channel count
Divide $299 by what Buffer Essentials would charge you each month at your channel count:
- 3 channels ($18/mo): about 16.6 months, which is longer than the year of updates Mixpost Pro includes. Buffer's free plan also covers 3 channels, so at this size the comparison is really Mixpost Lite vs Buffer Free, and Lite cannot post to Instagram or TikTok.
- 5 channels ($30/mo): about 10 months.
- 10 channels ($60/mo): about 5 months, or about 6 months against Buffer's annual rate.
- 25 channels ($120/mo): about 2.5 months.
- 50 channels ($195/mo): about 1.5 months, or under 2 against annual billing.
If you need several logins, compare against Buffer Team instead. Ten channels on Team cost $120 a month, so Mixpost Pro pays back in about 2.5 months, and Mixpost does not charge per person at all.
A one-time price is not a lower price. It is a price paid somewhere else: on your server, in your time, and at the platforms' own gates.
On subscription cost alone, Mixpost wins for anyone past a handful of channels, and it wins fast. The question is what the $299 does not include.
The costs that don't appear on Mixpost's pricing page
Mixpost is unusually candid about the first one. Its FAQ, asked whether there are limits on accounts or clients, answers:
"Mixpost allows you to connect unlimited social accounts and manage as many clients as you need - without restrictions. However, social networks like Facebook, LinkedIn, and TikTok may impose rate limits. If you reach a platform's limit, you can request a higher limit directly from them, though some may charge a fee for this."
That is a vendor telling you the unlimited is real on its side and not on the platforms' side. Buffer has platform limits too, but it deals with them for you. With a self-hosted tool, the relationship with each platform's developer program is yours.
The other costs follow from the same fact:
- Your own developer apps. Self-hosting means registering your own apps with each network you want to post to and getting them through that network's review. How long that takes is up to the platform, not Mixpost. We cover what vendors in this category say about approval waits in the three-layer bill of self-hosting.
- A server and whoever maintains it. Mixpost is a Laravel application you run. The license covers the software, not the machine, backups or upgrades.
- Month 13. Pro includes one year of updates. After that you keep a working version but not new platform fixes unless you renew, and the renewal price is not printed. Social APIs change often, so a scheduler that stops getting updates will eventually stop posting to something.
- One domain. Pro is licensed for one domain or subdomain. If you want separate installs per client, that is a separate purchase or the Enterprise license. The Pro license also cannot be used to build a SaaS product.
None of this makes Mixpost a bad deal. For a technical team that already runs servers and wants to own its publishing stack, it is often the best deal on the market. More on the license tiers in Mixpost Lite vs Pro and the one-time pricing breakdown.
Who should pick which
Pick Buffer if nobody on your team wants to own a server, if you are under about five channels (where Buffer Free or a small Essentials bill beats the payback period), or if you want someone else to absorb the platform-side API work. The per-channel bill grows with you, but its per-channel rate falls as it grows, and at 50 channels you are already paying $3 for each extra one.
Pick Mixpost Pro if you have a developer or can hire one for setup, you run ten or more channels, you want unlimited users without seat math, and you plan to renew updates or accept the risk of not doing so. Lite is only an option if Facebook Pages, Mastodon and X are really all you publish to.
One more thing both products share: they move content you already have. Neither writes a different post for each of twenty accounts. If that is the step eating your week, a scheduler is the wrong purchase, whichever way it bills. NoobClaw is one tool in that other category. It runs your own accounts in separate local browser profiles on your computer, with no passwords handed over, uses AI to draft distinct content per account and handle engagement at a human pace, and you should keep the human review step on. It sits upstream of a scheduler rather than replacing one. Its pricing is on the site and in the app.
FAQ: Mixpost vs Buffer
Is Mixpost really free?
Mixpost Lite is free and open source, but it only connects Facebook Pages, Mastodon and X. Instagram, TikTok, LinkedIn, YouTube and the other major networks need Pro ($299 once) or Enterprise ($1,199 once). You also pay for your own hosting either way.
How long until Mixpost Pro pays for itself compared with Buffer?
Against Buffer Essentials billed monthly, roughly 10 months at 5 channels, 5 months at 10, 2.5 at 25 and 1.5 at 50. At 3 channels it takes longer than the one year of updates Pro includes.
Does Mixpost have posting limits like Buffer's fair-use cap?
Mixpost sets no account or posting limits of its own. Its FAQ says the social networks may impose rate limits, and that raising them may involve a fee paid to the platform. Buffer's paid plans have a fair-use cap of 5,000 posts per channel.
