Honest pros and cons
What Postiz does well

- Very broad channel support including Reddit, Discord, Bluesky, and Mastodon
- Strong developer tooling: public API, webhooks, n8n and Make nodes, and an MCP server

- Self-hosting means maintaining servers and getting your own API approvals from each social platform
- No free hosted tier — only a 7-day trial before you pay or self-host
- No native iOS or Android mobile apps

Frequently asked questions
Is Postiz really free?
The open-source version is free to self-host, and that is a genuine advantage no closed-source tool can match. But you supply the server, keep it updated, and apply for your own API access with each social network — Postiz notes Meta and YouTube approvals can take over a month. The hosted version starts at $29/month with a 7-day trial.
Is Socialync cheaper than Postiz?
For hosted plans, yes at the entry tier. Postiz Standard is $29/month for 5 channels and 400 posts. Socialync starts at $20/month for 5 accounts across all 9 platforms, with no post cap. If you are comfortable self-hosting, Postiz can be cheaper in cash but more expensive in time.
Does Postiz support more platforms than Socialync?
Yes, Postiz still supports more networks, including Reddit, Discord, and Mastodon, which Socialync does not offer. Socialync now publishes image pins and carousel pins to Pinterest too, so that is no longer part of the gap. Socialync focuses on 9 core platforms (TikTok, Instagram, YouTube, Facebook, X, LinkedIn, Threads, Bluesky, Pinterest) and goes deeper on each, including TikTok personal accounts and mobile apps.
Both have AI agents — what is the difference?
Postiz offers a Smart Agent and an MCP server, and so does Socialync. The practical difference is the surrounding package: Socialync pairs its MCP server with simple metered pricing and mobile apps, while Postiz pairs its agent with open-source flexibility and developer tooling. Both are solid choices for AI-driven posting.
Can I switch from Postiz to Socialync easily?
Yes. There is no migration needed: sign up for Socialync, connect your accounts in a couple of minutes, and schedule fresh posts on the free plan, which is 5 posts a month with no card. Your Postiz setup can stay live while you compare.
