Our Analysis
Postiz schedules your social posts across every network from one calendar, as an open source app you can self-host. It supports Twitter/X, LinkedIn, Instagram, Facebook, TikTok, and more. The AI features generate post variations and suggest optimal posting times. You get a content calendar, team collaboration, and analytics. Self-hosting is free under AGPL-3.0. The cloud version at postiz.com has no free tier, just a 7-day trial: Standard is $29/mo for 5 channels, Team $39/mo for 10, Pro $49/mo for 30, and Ultimate $99/mo for 100. The catch: AGPL means if you modify the code and offer it as a service, you must open source your changes. The project is young and moving fast, expect rough edges and breaking changes. Self-hosting requires Docker, PostgreSQL, Redis, and an LLM API key for the AI features (OpenAI, etc.) which adds cost. And honestly, if you're one person managing one account, Buffer's free tier is less work to set up.
Mixpost schedules and publishes social posts from your own server, with a calendar, media library, post versions, and analytics that never phone home to anybody. It is a Buffer replacement you run yourself. The free Lite edition is MIT licensed and yours permanently. It is a Laravel application, so you need PHP, a database, and a queue worker actually running for scheduled posts to fire. Docker images exist and take most of the pain out. Budget an afternoon for the first install and a recurring hour whenever you upgrade. Here is the boundary that matters. Lite publishes to Facebook Pages, Mastodon, and X. That is the whole list. Instagram, LinkedIn, TikTok, YouTube, Pinterest, Threads, Bluesky, and Google Business Profile all sit behind Pro at $299 one time for a single domain, with Enterprise at $1,199. Solo on X and Mastodon: Lite works. Anyone posting to Instagram or LinkedIn: you are buying Pro. The catch is that the free tier gates the platforms most people came for, and the open source repo has been quiet since spring while the paid edition keeps moving. Still, $299 once is not $299 a year. Buffer's Team plan bills $10 per channel per month, so six channels runs $720 annually and Mixpost pays for itself inside of five months.
MultiPost skips the API problem entirely. It is a browser extension that pushes one piece of content to more than ten platforms by driving the sessions you are already signed into, so there is no login, no registration, and no API key to apply for. That architecture is the whole story. Getting official publishing access to Instagram or TikTok means an app review process that runs for weeks and frequently ends in rejection for small developers. An extension that fills in the same forms you would fill in yourself sidesteps every bit of it. Install it and start posting. Platform coverage leans Chinese: Xiaohongshu, Weibo, Zhihu, and Bilibili sit alongside TikTok and YouTube. For a Western only audience, a proper scheduler like gitroomhq/postiz-app or brightbeanxyz/brightbean-studio fits better. This is Apache licensed, free, and has nothing to sell you. The catch is that browser automation breaks whenever a platform changes its markup, and nothing publishes while your browser is closed. This is a distribution tool, not a scheduler. Anything that has to go out at 9am on Tuesday while you are asleep needs a server, and this is not one.
Eleven social networks with no paywall on any of them. BrightBean Studio plans, composes, schedules, approves, publishes, and monitors content across Facebook, Instagram, LinkedIn, TikTok, YouTube, Pinterest, Threads, Bluesky, Google Business Profile, Mastodon, and DEV.to. Approval workflows and team management are included, and the hosted version costs nothing either. Deployment is Docker Compose with Postgres, an app container, and a background worker. Migrations run automatically before the app starts, which removes the usual first boot ceremony. Python 3.12 and Node 20 will run it locally on SQLite if you just want to poke at it. No per seat pricing and no per channel limits, which is precisely the thing that costs money everywhere else in this category. Solo creators and small agencies benefit most. Compare it against inovector/mixpost, where the free edition reaches three networks and everything past that is a $299 license. The catch is age. This project started in spring 2026, and eleven platform integrations means eleven OAuth flows and eleven APIs that break on somebody else's schedule. gitroomhq/postiz-app has more road behind it. Read the issue tracker before you put a paying client's account on it.
Twelve networks, one price, no per seat tax. trypost is a calendar first social scheduler that publishes natively to Instagram, Facebook, LinkedIn, X, TikTok, YouTube, Pinterest, Threads, Bluesky, Mastodon, Telegram, and Discord. Drag a post to a new slot and it moves. Self-host it under AGPL for nothing, or pay for their cloud. The backend is PHP and Laravel with a Vue frontend, and Docker compose files ship in the repo. The self-hosted path looks like every other Laravel app: web server, database, queue worker. Nothing exotic and nothing surprising. Cloud is $10 a month per workspace, or $120 a year, with unlimited teammates and no feature gating. AI, analytics, approvals, the API, and MCP ship on every plan. That pricing is aggressive against Buffer, which bills per channel, and against Hootsuite, which bills per seat. Five teammates across six channels costs the same $10 as one person on one channel. The catch is that a flat workspace price only stays cheap while the company can survive on it, and pricing this far under the market usually moves. AGPL self-hosting is your insurance policy.
