Postiz is an open-source social media scheduling tool from the Gitroom team, licensed under AGPL-3.0 and fully self-hostable — the project states there is no difference between the hosted version and the self-hosted version. You connect your accounts and manage posting from a visual calendar plus a chat-driven Smart Agent, publishing to a broad set of networks: Instagram, TikTok, YouTube, LinkedIn, X, Facebook, Pinterest, Threads, Bluesky, Mastodon, Reddit, Discord, and more.
The Smart Agent is the headline. Instead of filling out a post form, you tell it in plain language what you want — "draft a LinkedIn post about our launch, make a matching image, and schedule it for Tuesday" — and it drafts the copy, generates a visual, and queues the post. In 2026 Postiz leaned into the agentic framing at the protocol level too: it exposes an MCP server and a CLI, so an external AI agent like Claude or ChatGPT can list your connected accounts, create posts, upload media, and schedule content on your behalf. Alongside that it ships a public API, a Node SDK, and integrations for n8n and Make.com.
Pricing on postiz.com starts around $29/month (Standard, 5 channels) and rises through Team, Pro, and Ultimate (~$99, 100 channels), with roughly 20% off annually and a 7-day free trial; AI image and video allowances scale by plan, and unlimited team members come in from the Team plan up. Because it's AGPL-3.0, you can also run the whole product for free on your own infrastructure. Treat specific tiers and allowances as a snapshot and confirm them on postiz.com.
The honest framing for a creator: Postiz is a scheduler with a chat layer, not a content engine. Its AI drafts captions and hashtags, makes generic text-to-image visuals, and produces short AI clips — but it has no long-form-to-short clipping, no avatar/persona video, no face-locked persona, no brand-exact carousel builder, no governed brand voice, and it doesn't write full blog articles or newsletters. It's excellent at scheduling and automation; producing a deep, on-brand, multi-format content set from one source is a separate job.
The clever thing Postiz gets right is the prompt-to-post loop: you say what you want and the Smart Agent drafts a caption, makes an image, and schedules it. The ceiling is that this produces one post at a time — a caption plus a generic visual — and stops there. That's the exact seam [Kompozy](/) fills, and the two fit best as a producer-feeds-scheduler pair rather than as rivals. The same idea you'd type into the Postiz agent becomes a content *seed* in Kompozy, which grows it into a full multi-format release instead of a single post.
Take one topic and let Kompozy spin the batch Postiz can't generate. Its argument becomes a [Persona Short](/glossary/persona-shorts) or a HeyGen avatar cut with a real face and voice; its key points become a brand-exact [Carousel](/glossary/hyperframes) and a set of Quote Graphics; a long recording becomes [Clipped Shorts](/glossary/output-buckets) with burned-in captions, reframed to 9:16 for Reels, Shorts, and TikTok; and the same seed also drafts a [Blog Article](/glossary/output-buckets) and an Email Newsletter. Every piece is held to one [Persona Brief](/glossary/persona-brief) and banned-word filters, so a whole week of output reads as one brand — not a generic AI caption bolted to a stock image. If you run Postiz self-hosted, this is especially clean: Kompozy is the generation engine, Postiz is the distribution endpoint you already own. Where the two overlap on publishing, it's a fair split — Postiz reaches more raw networks, while Kompozy's own [Autopilot](/glossary/autopilot) publishes across the eight social platforms plus blog and email behind a per-post review. Postiz schedules a post; Kompozy produces the content that's worth scheduling.
Postiz is an open-source, self-hostable social media scheduling tool from the Gitroom team, licensed under AGPL-3.0. It publishes to a broad set of networks from a visual calendar and a chat-driven Smart Agent, and it exposes a public API, an MCP server, and a CLI so external AI agents can drive it. You can self-host the full product for free or use the paid hosted plans from ~$29/month.
A scheduled posting queue across many networks, chat-drafted posts with copy and a matching AI image, generic text-to-image visuals, and short AI clips (allowances scale by plan). Its output is scheduled social posts with light AI assist — not long-form-to-short clips, avatar video, brand-exact carousels, blogs, or newsletters.
Mostly it schedules, with post-level AI assist. The Smart Agent drafts captions and hashtags, makes a generic image, and produces short clips — but there's no long-form clipping, avatar/persona video, face-lock, brand-exact carousel builder, governed brand voice, or blog/newsletter generation. For deep multi-format generation, pair it with a content engine like Kompozy.
Use the same topic as a seed in Kompozy instead of a single Smart Agent post. Kompozy grows it into a Persona Short or avatar cut, a brand-exact carousel, quote graphics, clipped shorts, a blog article, and a newsletter — all in one Persona Brief voice — then publishes across eight social platforms plus blog and email. If you self-host Postiz, you can also export the finished assets into its queue.
It can be. Postiz is AGPL-3.0 and self-hostable with parity to the hosted version, so you can run the whole product for free on your own infrastructure. The managed hosted plans start around $29/month with a 7-day free trial. Self-hosting is free in dollars but you own the deployment, updates, and uptime.
