Postiz FAQ
- Is Postiz free?
- Postiz itself is free, but it needs an API key for an external AI service. That service charges separately, though some have a free tier.
- Do I need to install anything or write code to use Postiz?
- You install it like a normal desktop app. No command line involved.
- Does Postiz work on a phone?
- No. It needs a computer.
- Can I use Postiz commercially?
- The licence is AGPL-3.0. Using it commercially is fine, but if you distribute something built on it you may be required to release that under the same licence. Keep it internal, or check before distributing.
