Postiz

What is Postiz?

Postiz is an open source social media scheduling tool that lets you plan, create, and publish content to 30+ social networks from a single drag-and-drop calendar. You connect your accounts — X, Instagram, LinkedIn, TikTok, YouTube, Facebook, Threads, Bluesky, Mastodon, and more — write a post once, tailor it per platform, and schedule it all from one place. It’s built by Gitroom and released under the AGPL-3.0 license.

What is Postiz best for?

Creators, agencies, and small marketing teams that want Buffer- or Hootsuite-style scheduling without a per-channel monthly bill — and want to keep their content and audience data on their own server. It’s a strong fit for technical users comfortable running Docker, and for anyone wiring publishing into automations through n8n, Make, or Zapier via its public API.

What can Postiz do?

• Schedule and cross-post to 30+ networks — X, Instagram, LinkedIn, TikTok, YouTube, Facebook, Pinterest, Reddit, Threads, Bluesky, Mastodon, Discord, Slack, and Dribbble
• Plan a content calendar with drag-and-drop scheduling and per-platform previews
• Generate copy, images, and short videos with built-in AI (the AI copilot / Smart Agent)
• Design graphics in a built-in Canva-style editor without leaving the app
• Track engagement, reach, and audience analytics across connected accounts
• Collaborate with teammates, and buy or sell posts in a built-in creator marketplace
• Automate publishing through a public API and native n8n, Make, and Zapier integrations
• Self-host with Docker (PostgreSQL + Redis), or use the managed Postiz cloud

Is Postiz free?

Yes — Postiz is free and open source under the AGPL-3.0 license, so you can self-host it at no software cost and only pay for your server (a small VPS or a ~$5/mo three-service stack is enough). The managed Postiz cloud is the paid, hands-off option, starting at $29/mo for 5 channels and 400 posts and scaling to $99/mo for 100 channels, after a 7-day free trial. There’s no free tier on the cloud — the free path is self-hosting.

Where does Postiz fall short?

• AGPL-3.0 is a strong copyleft license: you’re free to self-host and modify, but if you offer a modified version as a network service you must publish your changes. That’s stricter than the permissive licenses some teams expect.
• Self-hosting is a real ops job — you run PostgreSQL, Redis, and the app (about 2GB RAM minimum), handle your own upgrades, and register a developer app/API key for each network you connect (X in particular can be fiddly).
• It’s a fast-moving young project, so features and integrations change quickly and there are fewer troubleshooting threads to lean on than with established SaaS schedulers.

What does Postiz replace?

Postiz is a self-hosted alternative to Buffer and Hootsuite, plus similar schedulers like Later and Typefully. It does the same plan-write-schedule-analyze job across your social accounts, but you run it on your own infrastructure under an open source license instead of paying a monthly per-channel subscription.

FAQ

Is Postiz open source? Yes — genuinely. Postiz is licensed under AGPL-3.0, an OSI-approved open source license, so the full code is public and free to self-host, modify, and use. The copyleft terms only require you to share your source if you distribute a modified version as a network service.

Can I self-host Postiz for free? Yes. Self-hosting is free; you only pay for the server. It runs as a Docker stack with PostgreSQL and Redis and needs roughly 2GB of RAM — a small VPS or a ~$5/mo managed deploy handles it.

Is Postiz a good Buffer or Hootsuite alternative? For technical users and teams that want data ownership and no per-channel fees, yes — it covers scheduling, analytics, and AI content in one app. If you want zero setup and don’t mind a subscription, hosted Buffer or Hootsuite is simpler.

What do I need to run Postiz? A server with Docker, a PostgreSQL database, and Redis (about 2GB RAM minimum). You’ll also register a developer app/API key for each social network you want to connect.
