Open-source, self-hosted social media management — schedule and publish from your own server with no monthly subscription.
Last verified · 2026-08-05 · by Moe Ameen
Mixpost is an open-source, self-hosted social media management platform built by Inovector. You run it on your own server — Docker, a Laravel package, or a manual install on any VPS — and it becomes your private scheduler and publisher: connect accounts, compose posts, drop them in a calendar, and Mixpost publishes on your schedule. It's built on Laravel with Inertia.js, Vue 3, and Tailwind, and it's positioned openly as a self-hosted Buffer alternative for people who want to own their data and skip recurring SaaS fees.
The pricing model is the headline. Instead of a monthly subscription, Mixpost sells a one-time license: a free open-source Lite edition, plus paid Pro and Enterprise tiers that unlock more platforms and features. At the time of writing the paid tiers are one-time purchases (Pro around $299, Enterprise around $1,199) that include a year of updates and a perpetual fallback license, with no per-account or per-seat caps — you can connect unlimited social accounts and add unlimited team members. Confirm current figures on Mixpost's pricing page before buying.
Platform coverage depends on the edition. Lite covers Facebook Pages, X, and Mastodon; Pro and Enterprise add Instagram, LinkedIn, YouTube, TikTok, Pinterest, Threads, Bluesky, and Google Business Profile. Around the scheduler sit the features a working operator expects: a content calendar, per-network post versions and conditions, dynamic variables, hashtag groups, analytics on post and audience activity, a unified inbox for mentions and comments, team roles, and approval workflows. Higher tiers add white-label branding, an API, and subscription/billing tooling for agencies that resell it.
Mixpost also ships an AI layer. Its AI Assistant can draft text and generate images with a configurable brand voice, and it exposes an MCP (Model Context Protocol) server so assistants like Claude can connect to your Mixpost instance and draft, schedule, and publish posts by chatting. That's genuinely useful for copy and light visuals — but it's a caption-and-image assistant bolted onto a scheduler, not a full production studio. Mixpost does not clip long-form video, generate talking-head or avatar video, or render brand-exact carousels and design templates.
Mixpost's strength is ownership: your accounts, your data, your server, one payment. Its AI Assistant writes captions and makes basic images, and its MCP server even lets Claude schedule text for you. What it never claims to be is a video and design studio — no clip detection, no talking-head or avatar video, no brand-exact carousels. That's the exact seam where Kompozy fits, and the two overlap far less than they complement.
Use Kompozy as the generation floor above your self-hosted queue. Point it at a podcast, a long video, an RSS feed, or a Persona Brief and it produces the heavy formats Mixpost can only distribute: HeyGen persona and avatar shorts with burned-in captions, Clipped Shorts cut from long footage, multi-slide carousels rendered pixel-exact through HyperFrames, quote graphics, blog drafts, and newsletters — all held to one voice by the Persona Brief and face-locked to a consistent AI Influencer persona. Kompozy persists every finished asset to durable storage, so you can either publish it through Kompozy's own scheduler across the eight social platforms plus blog and email, or export the file into Mixpost's queue when you want everything flowing through your own server. In practice: Kompozy manufactures the week of video, image, and long-form assets; Mixpost keeps them running on infrastructure you control.

Mixpost uses one-time pricing rather than a subscription. There's a free open-source Lite edition, and paid Pro and Enterprise tiers (around $299 and $1,199 at the time of writing) that are one-time purchases including a year of updates and a perpetual fallback license, with unlimited accounts and team members.

No. Mixpost's AI Assistant drafts text and generates images with a brand voice, and its MCP server lets assistants like Claude schedule posts, but it does not clip long-form video, generate talking-head or avatar video, or render brand-exact carousels. Those are made in a separate creation tool and scheduled through Mixpost.
It depends on the edition. Lite supports Facebook Pages, X, and Mastodon; Pro and Enterprise add Instagram, LinkedIn, YouTube, TikTok, Pinterest, Threads, Bluesky, and Google Business Profile. You can connect unlimited accounts per network.
Generate the assets Mixpost can't make in Kompozy — persona and avatar shorts, clips, carousels, quote cards, blogs, and newsletters from one source in your brand voice — then either publish through Kompozy across the eight social platforms plus blog and email, or export the files into your self-hosted Mixpost queue to distribute on your own server.
