Mixpost Alternatives (2026): Pick by the Reason You Are Leaving, Not by a Feature List

People do not search "mixpost alternative" because Mixpost is bad. They search it for one of three specific reasons, and the three reasons point at three different products. If you need Instagram or TikTok, the free Lite edition cannot post there. If you looked at the Lite repository this month, you saw a last commit dated March 16, 2026. If you priced Pro, you saw $299 once for one domain and read the clause that says a Pro licence "cannot be used to build a SaaS platform."

So this is three routes, one per reason, with every price read on September 28, 2026 from the vendors' pages and every repository date from the GitHub API the same day. For the head-to-head instead, see Postiz vs Mixpost.

Which of the three Mixpost problems are you actually leaving?

Start with what mixpost.app/pricing says today. Lite is free and lists "Publish on Facebook Pages", "Publish on Mastodon profiles" and "Publish on X profiles". Pro is $299 with "1 domain or subdomain", "1-Year free updates" and "Publish on all social platforms". Enterprise is $1,199 and adds white-label branding, subscription management and billing. Every purchase carries a "perpetual fallback license", and the FAQ spells out the update rule: "you will receive free updates for 1 year. After 1 year, you can continue using the software, but you will not receive updates unless you renew the license. For Mixpost Lite, you will receive updates forever at no additional cost." The renewal price is not on the page.

The last sentence is the one to test. On September 28, the GitHub API for inovector/mixpost (MIT, 3,738 stars) returns a pushed date of 2026-03-16, a latest commit of "Update CHANGELOG" on the same day, and a latest release of 2.6.0, also 2026-03-16. The release before that was 2.5.0 on 2026-02-24. Nothing since.

Now open the paid product's Pro changelog. It lists v4.9.0 on March 16, 2026, the same day as Lite's last release, then 28 more entries from v5.0.0 on April 17 to v6.3.1 on August 21. The vendor has not stopped shipping. It has not shipped the free tier since March 16.

"Updates forever" is a promise about price. A commit log is a record of behaviour. When the two disagree, plan around the log.

Whether a six-month gap matters depends on which networks you are on. Lite talks to three APIs; a March install still works today if none of them changed. The risk is that the next platform change lands on a codebase nobody is committing to. The update window as a purchase term is covered in Mixpost Lite vs Pro.

There is a third thing on the page worth knowing before you leave. A hosted edition exists at cloud.mixpost.app ("Schedule posts, manage every account, and collaborate with your team without the server setup"). It shows no price, and its Pricing link goes back to the self-hosted pricing page. So the "I do not want to run a server" reader currently has nowhere on Mixpost's site to find a number.

Route 1: open source that is still moving (Postiz)

If the reason is the commit log, the alternative has to pass the same test. gitroomhq/postiz-app is AGPL-3.0 with 36,415 stars, a pushed date of 2026-09-26, and release v2.24.0 on 2026-09-22. Its last 30 releases span December 2025 to September 2026 with at least one every month. The September one is a security fix, and ten recent releases open with an "upgrade immediately" notice: active means you keep up too.

What you get for it: Postiz Cloud is $29 a month for 5 channels, $39 for 10, $49 for 30 and $99 for 100, or $23, $31, $39 and $79 on yearly billing, with a 7-day trial and no permanent free hosted tier. The self-hosted build is free, and the cloud overview is unusually direct about the difference: "The difference is not the feature set, it is who does the work: the provider developer apps are already" registered on the hosted side, while a self-hosted install "behaves as the top tier" with no channel cap.

Two sentences on the pricing page price that trade. On direction: "Self-hosting is a secondary option; the hosted platform is where the agent features ship first." On credentials: "Facebook, Instagram, Threads and YouTube are more involved: they usually take more than a month, with several rounds of changes to the submission, privacy policy and terms of service." Postiz sells an optional app-approval service for people who would rather not do that themselves, and the page says you do not have to buy it.

Mixpost's own docs make the same point for TikTok, and more sharply. The TikTok setup page says "TikTok requires a fully developed website to approve your application; they do not approve it for private use or similar purposes," and then: "TikTok requires that your application be intended for a wide audience and not restricted to internal or private use. As a result, only users with a Mixpost Enterprise license are eligible to request an App Review process." Read that before assuming TikTok is a $299 feature. The credential work moves from vendor to you and does not disappear when you switch projects.

Runtime weight is the other difference. Mixpost's server page asks for PHP 8.3 or newer, MySQL, Redis, Supervisor and FFmpeg on a primary domain or subdomain. Postiz's system requirements list PostgreSQL, Redis and Temporal; the case for something lighter is in Postiz alternative, open source.

Route 2 and 3: pay per channel or per account instead of per domain

If the reason is Instagram and TikTok and you never wanted a server, the honest alternatives are hosted tools that meter something. Two meters exist, and they produce different bills for the same account list.

Per channel: Buffer has a free plan of 3 channels with 10 scheduled posts each, refilled as posts publish. Essentials is $6 per channel for channels 1 to 10, $4 for 11 to 25, $3 for 26 to 50 and $1 from 51, so 10 channels cost $60 and 50 cost $195. Paid plans are "unlimited" under a fair-use cap of 5,000 posts per channel. The break-even against Mixpost Pro at each channel count is worked out in Mixpost vs Buffer.

Per account: SocialBee is $29 for 5 profiles, $49 for 10, $99 for 25, with a block of 5 more profiles at $15 a month and the rule that "2 Instagram profiles, 1 Facebook page, and 2 X (Twitter) profiles" count as 5 accounts.

At 10 accounts over two years: Mixpost Pro plus an assumed $24-a-month server is $875. Postiz Cloud Team at $39 is $936. SocialBee Accelerate at $49 is $1,176. Buffer at $60 for 10 channels is $1,440. Postiz self-hosted plus the same server is $576. The licence line crosses Buffer at about month 8, SocialBee at about month 12 and Postiz Team at about month 20; the vertical line at month 12 is where Mixpost's included updates end. The $24 is our assumption for a 4 GB VPS, not a vendor quote; substitute your own.

The row the chart cannot show usually decides it: the subscriptions include the vendor's approved developer apps; the two self-hosted lines do not. If you can get a Meta app through review and do not need TikTok, the bottom two lines are real. If not, only the middle three publish on day one. The full three-layer bill is in Mixpost pricing: $299 once.

What none of these alternatives replace

Every tool above, Mixpost included, is a distribution layer. You hand it a finished post and it delivers it through the platform's API to the connected accounts. Right for a brand team with a calendar; the wrong half of the problem for someone running ten accounts that each need their own post, because a scheduler does not write ten posts; it copies one.

If that is your situation, the alternative is not another scheduler. NoobClaw, for example, is a desktop app rather than a hosted API tool: each account runs in its own local browser profile on your machine (you log in yourself; no passwords are handed over), AI drafts different content per account from that account's niche and persona, and posting runs at a human pace with a review step you should keep switched on. It is priced per action and per piece rather than per domain, channel or seat; current figures are on its site and in the app. It is the right route only when the bottleneck is producing distinct content for many accounts, not delivering one piece to many.

A twenty-second check for any candidate: open the repository, read the pushed date and the latest release, then open the vendor's paid changelog and compare. The gap between those dates is the number this search was about.

FAQ: Mixpost alternatives

Is Mixpost still maintained?

The paid Pro edition is. Its changelog shows 28 releases between April 17 and August 21, 2026, the latest v6.3.1. The free open-source Lite repository (inovector/mixpost) has had no commit and no release since 2.6.0 on March 16, 2026, as read from the GitHub API on September 28, 2026.

What is the best open-source alternative to Mixpost?

Postiz is the one with a live commit log: AGPL-3.0, release v2.24.0 on September 22, 2026, self-hostable with an effectively unlimited channel cap (Postiz's own wording), and a hosted plan from $29 a month for 5 channels if you would rather not run it. Its docs describe self-hosting as a secondary option, and you still register your own developer apps with each platform.

Is there a free Mixpost alternative that posts to Instagram and TikTok?

Buffer's free plan covers 3 channels with 10 scheduled posts each and supports business Instagram accounts; TikTok on Buffer needs a business profile. Postiz self-hosted is free software but posts to Instagram and TikTok only once your own developer apps are approved, which Postiz says can take more than a month for the Meta family. Mixpost Lite itself cannot post to either.
