Postiz

Postiz is a social media scheduling platform: you queue and cross-post to 25+ networks from one shared calendar, with drag-to-reschedule and click-to-edit. A built-in AI copilot drafts and rewrites posts and generates images, and every plan adds team workspaces, analytics, an API with webhooks, and RSS auto-posting.

There are two ways to run it. The managed cloud at postiz.com needs no infrastructure and starts at $29/month. Or you self-host the open-source (AGPL-3.0) build for free and run the servers yourself. Same core product; the difference is who operates it.

Channel breadth no incumbent matches at the price. Where Buffer sticks to the popular networks and charges per channel, Postiz covers rarer ones (Bluesky, Mastodon, Threads, Reddit) at a flat rate. On Reddit's r/selfhosted and r/SaaS it gets named alongside Mixpost as one of the few viable open-source schedulers, with practitioners singling out that rare-channel support.

The calendar is genuinely fast (drag to reschedule, no lag), development is near-daily, and the project carries 34.9k GitHub stars. If you post to more than a couple of networks, the flat model is usually cheaper than a per-channel tool.

Support is the weak spot. A self-hoster on r/selfhosted put it plainly: "Support doesn't exist pretty much; there are too many users and not enough staff." On the paid cloud you get more, but confirm response times before you rely on it for time-sensitive posting.

Connections drop. Channels disconnect and logins expire (YouTube needs Google's app review to stay connected), and when a network changes its rules, posting can break until a fix ships. Platform approvals for Instagram, TikTok, Facebook, and LinkedIn business accounts are still on you.

If you self-host, budget for setup friction — first-time configuration trips many users. The managed cloud removes the infra work, not the approvals.

The cloud is flat monthly by channel count, with unlimited posts on every tier: Standard $29 (5 channels, 3 AI videos), Team $39 (10 channels, unlimited members, 100 AI images), Pro $49 (30 channels, 300 AI images), and Ultimate $99 (100 channels, 500 AI images). A 7-day trial is available.

Self-hosting is free under AGPL-3.0 if you run the infrastructure. The number worth working out: at your channel count, does Postiz's flat plan beat a per-channel incumbent, and is your real constraint infra effort (favor cloud) or vendor support (favor a supported competitor)?
