Postiz self-hosted: replacing Buffer for a 3-person team
A team with 10 social channels across two brands moved from Buffer to self-hosted Postiz. It is an open-source scheduler with a shared calendar, an approval flow and team workspaces, and it posts to 14 networks. It also has optional AI post generation with your own OpenAI key, and it doesn't charge per channel or per seat.
Setup steps
- Pick hosting: a VPS you run, a one-click PaaS template, or a managed Postiz host
- Deploy Postiz with PostgreSQL, Redis and Temporal
- Create your admin account, then set DISABLE_REGISTRATION=true
- Create your own OAuth developer app on each social network and paste in the keys
- Invite teammates and schedule posts from the shared calendar

How it went
Postiz has run on a $15/mo server for a few months for three people and 10 channels across two brands. The writer says adding an eleventh channel or a fourth teammate costs nothing.
Worth knowing
The real friction is creating your own developer app on every network, and X and Meta reviews can take days or be bounced. Set DISABLE_REGISTRATION=true after creating your admin account. You are on call for backups and updates.

Help me set up this automation using Postiz (open source, AGPL-3.0) + optional OpenAI key: "Postiz self-hosted: replacing Buffer for a 3-person team". Goal: replace Buffer/Hootsuite social media scheduler. How it should work: - Trigger: You or a teammate schedules a post - Then: An approval step if you want one - Then: Optional AI writes post drafts (your OpenAI key) - Then: Postiz publishes at the set time - Result: Posts go out on up to 14 networks Setup steps (summarized from the original source): 1. Pick hosting: a VPS you run, a one-click PaaS template, or a managed Postiz host 2. Deploy Postiz with PostgreSQL, Redis and Temporal 3. Create your admin account, then set DISABLE_REGISTRATION=true 4. Create your own OAuth developer app on each social network and paste in the keys 5. Invite teammates and schedule posts from the shared calendar Guide me one step at a time. Ask me for anything you need (accounts, sheet or channel names) before you start. Safety rules: - Build and test with sample data first, and show me a sample result before anything goes live. - Keep anything that goes to other people (emails, posts, replies, record updates) as drafts for my review until I say otherwise. - Never send, post, buy, pay, delete or change records without my approval. - Tell me about any cost (paid plans, API usage) before I'd incur it, and help me set a spending limit. - Keep API keys and passwords out of shared docs and chats. - Privacy: Accounts and post history live on a server you control. AI post generation sends text to OpenAI only if you add a key. Based on: https://dev.to/vikasprogrammer/buffer-wanted-100mo-so-i-self-host-postiz-for-15-dfa
