Postiz
Open-source social media scheduler with AI Copilot, RSS auto-post, webhooks, and a public API
Postiz is the systems-first choice for growth marketers and creator-operators who need to automate cross-posting, RSS syndication, and API-driven publishing. Our take: it’s strongest when you treat social posting like a pipeline, not a one-off task. Expect some ops overhead if you self-host.
Why we love it
- Best for building an always-on content engine: RSS auto-post + repeated posts reduce “empty calendar” weeks
- Webhooks + Public API make it easy to wire Postiz into n8n/Make/Zapier (publish → alert → log → repurpose)
- Paid plans bundle automation features (API, webhooks, scheduling comments, delays) that usually require add-ons elsewhere
Things to know
- If you self-host, reliability becomes your responsibility (updates, storage, OAuth provider setup)
- Cloud pricing starts at $29/mo, which is not the cheapest for solo creators who only need basic scheduling
- Advanced platform providers can break as social APIs change; you may need occasional troubleshooting
About
Postiz is an open-source, automation-first social media scheduler built for modern Marketing Tools stacks.
Workflow automation you actually feel: schedule and cross-post, run repeated posts, publish RSS auto-post feeds, and trigger downstream actions via webhooks—so your content engine keeps shipping even when your team is offline.
Price-to-value: Postiz offers a free self-hosted option, with paid cloud tiers starting at $29/month. It is about average for social scheduling SaaS, but unusually strong on automation (API + webhooks) for the price.
For systems builders, the killer feature is the Public API: authenticate with an API key, schedule multiple posts per request, and connect to Automation Tools like n8n/Make/Zapier for end-to-end pipelines (CMS → AI copy → publish → analytics alert).
Key Features
- ✓Schedule & cross-post to keep multi-channel campaigns consistent automatically
- ✓Auto-publish from RSS feeds to turn blogs/videos into always-on social distribution
- ✓Trigger workflows with webhooks when posts publish (alerts, archiving, re-post rules)
- ✓Automate publishing via Public API (batch scheduling + programmable integrations)
Frequently Asked Questions
Yes—if you self-host. Postiz is open-source, so you can run it for free on your own infrastructure. If you prefer Postiz Cloud, paid plans start at $29/month and include features like API access, webhooks, RSS auto-post, repeated posts, and AI Copilot.
The main difference is that Postiz is open-source and built for automation via API + webhooks, while Buffer is typically simpler and SaaS-only, and Hootsuite leans enterprise with broader governance but higher cost. If you want a programmable posting pipeline (RSS → AI copy → schedule → webhook), Postiz is usually the better fit.
Yes. Postiz provides a Public API with API-key authentication and a cloud base URL of https://api.postiz.com/public/v1; the docs list a 30 requests/hour rate limit, and recommend batching multiple scheduled posts in one request to maximize throughput. For integrations, combine the API with webhooks and no-code automation platforms like n8n and Make.com.
