Deploy and Host self hosted Postiz YouTube (Self-Hosted YouTube Scheduling Setup) on Railway

This template deploys Postiz on Railway with the YouTube provider wired up the way the Postiz docs describe.

About Hosting Postiz YouTube open-source software on Railway (self hosted Postiz YouTube connection and scheduled uploads on Railway template)

Self-hosting Postiz keeps your scheduling data, uploaded videos, and YouTube OAuth credentials in a project you control.

Railway handles provisioning, the private network to Temporal on port 7233, the volumes, and the HTTPS domain Google requires.

Why Deploy Postiz YouTube, the Buffer alternative on Railway (Railway Free Trial)

Buffer charges per channel, so the bill grows with every YouTube channel and network you add.

Railway is a singular platform to deploy your infrastructure stack. Railway will host your infrastructure so you don't have to deal with configuration, while allowing you to vertically and horizontally scale it.

By deploying Postiz YouTube on Railway, you are one step closer to supporting a complete full-stack application with minimal burden. Host your servers, databases, AI agents, and more on Railway.

Railway vs Other Hosting Providers and VPS for Postiz YouTube self hosting

Railway trades some control for a managed deploy, while a VPS leaves the server to you. Here is how the usual choices compare.

Provider	What You Get with Railway	What You Get with the Other Provider
DigitalOcean	Four services from one template, HTTPS on the generated domain, no Docker setup.	A Droplet with root access and a fixed price, but you install Docker, handle TLS, and patch the OS.
AWS	One project for the whole stack, without learning VPC or IAM for a light scheduler.	Deep networking control, with a steeper learning curve and a harder-to-predict bill.
Hetzner	A managed deploy with the Google OAuth redirect set to your Railway domain.	Low cost per gigabyte of RAM, but you own uptime, backups, and the OAuth callback setup.

Pick Railway if you want the YOUTUBE_CLIENT_ID and YOUTUBE_CLIENT_SECRET variables working without touching a server.

Common Use Cases for hosted Postiz YouTube

Scheduling a week of YouTube uploads from one dashboard: Queue videos and Shorts next to X or LinkedIn posts in one Postiz calendar.
Keeping a team's channel credentials on your own Railway project: The Google client ID and secret live in your postiz service variables, not a SaaS account. Set DISABLE_REGISTRATION to true once your team has signed up.
Queuing uploads for a Brand account through Google Workspace admin: Brand channels need the OAuth app trusted under API Controls in admin.google.com, and the docs say to wait about 5 hours before connecting.
Testing the OAuth flow locally before deploying: The docs list localhost redirect URIs, so you can check the consent screen and test users first.
Reducing per-channel SaaS fees for a small agency: Buffer prices per channel, so several client channels add up. Self-hosting on Railway runs roughly $10-25/mo at light use.

Dependencies for Postiz YouTube Docker hosted on Railway

Postiz YouTube runs as four services on Railway, and the YouTube connection only works once the Google side is set up correctly.

Deployment Dependencies for Managed Postiz YouTube Service (Social Media Scheduler)

postiz: the app container with frontend, backend API under /api, and workers. Public port 5000, volume at /uploads.
Temporal 1.28.1: runs scheduled posts. It stays private and is reached on port 7233.
Postgres 18: the database, with its own volume.
Redis 8.2: the cache and queue store, with its own volume.
Google Cloud project: holds the YouTube Data API v3 enablement and the OAuth client. Add yourself as a test user.

Implementation Details for Postiz YouTube (Using Postiz official docker image)

Set MAIN_URL and FRONTEND_URL to https://RAILWAY_PUBLIC_DOMAIN and NEXT_PUBLIC_BACKEND_URL to that domain plus /api.

YOUTUBE_CLIENT_ID=""
YOUTUBE_CLIENT_SECRET=""

Set NOT_SECURED=true while you log in over the default up.railway.app domain.

How does Postiz YouTube compare against other ways to schedule YouTube uploads against YouTube Studio, Buffer, Hootsuite and Later

Postiz YouTube vs YouTube Studio scheduling (YouTube Studio Alternative)

Scope: YouTube Studio's native scheduler covers YouTube only. Postiz lets you queue YouTube uploads alongside posts for other networks from one calendar.
Setup cost: Studio needs no Google Cloud project. Postiz needs one, plus an OAuth client, so expect more setup time.
Data control: Studio keeps scheduling data on Google's side. On Railway, your YOUTUBE_CLIENT_ID and YOUTUBE_CLIENT_SECRET stay in your own project.

Postiz YouTube vs Buffer (Buffer Alternative)

Pricing model: Buffer is hosted SaaS priced per channel. Postiz is AGPL-3.0 and free to self host, so you pay only for Railway compute.
Hosting: Buffer needs nothing from you. Postiz runs four services (postiz, Temporal, Postgres and Redis), so Buffer wins if you'd rather not manage infrastructure.

Postiz YouTube vs Hootsuite (Hootsuite Alternative)

Audience: Hootsuite targets larger teams with per-user pricing. Postiz suits creators and small teams who want one self-hosted instance.
Feature depth: Hootsuite offers mature reporting, approval workflows and enterprise support that a self-hosted Postiz won't match out of the box.
Ownership: You own the database and uploads volume on Postiz, which matters if your scheduling history must stay on your own server.

Postiz YouTube vs Later (Later Alternative)

Focus: Later is a SaaS planner built around visual content, especially Instagram and TikTok. Postiz is a general scheduler covering YouTube and many other networks.
Visual planning: Later's grid-style planning is stronger if your workflow is mostly visual. Postiz's calendar works better for video queues.
Control: Postiz runs in your Railway project with your own OAuth credentials, while Later keeps accounts on its hosted platform.

How to self host Postiz YouTube on other VPS Services (Postiz self hosting guide)

This section covers running the official Postiz Docker setup on your own VPS.

Clone the Repository

Clone the upstream project, which is AGPL-3.0 licensed.

git clone https://github.com/gitroomhq/postiz-app.git
cd postiz-app

Install Dependencies

The official docker compose file starts postiz-app, Postgres, Redis and Temporal, so you only need Docker and Docker Compose on the VPS.

Configure Environment Variables

Copy the example env file and set your public domain.

cp .env.example .env
MAIN_URL="https://your-domain.com"
FRONTEND_URL="https://your-domain.com"
YOUTUBE_CLIENT_ID="your-client-id"
YOUTUBE_CLIENT_SECRET="your-client-secret"

Register https://your-domain.com/integrations/social/youtube as the Authorized redirect URI in Google Cloud so it matches exactly.

Start the Postiz YouTube Application

Bring the stack up in the background and watch the logs.

docker compose up -d
docker compose logs -f postiz

Open your domain, sign up as the first user, and connect YouTube from the Postiz UI.

Official Pricing of Postiz YouTube (Postiz pricing)

Postiz itself is free and open source under AGPL-3.0, so self hosting it on Railway costs you nothing in license fees.

Postiz YouTube cloud vs self hosted comparison (Pricing, features, costs, and more)

Running Postiz yourself means you pay Railway for the server and keep the Google OAuth credentials, the channel tokens and the scheduling queue on your own project.

Monthly cost of self hosting Postiz YouTube on Railway

The Postiz software itself is free under AGPL-3.0.

System Requirements for Hosting Postiz YouTube on a VPS

If you move off Railway, plan for roughly 2 GB of RAM or more, a domain with HTTPS (Google's OAuth redirect will not accept plain http for production), and enough disk for the /uploads volume.

Frequently Asked Questions (FAQs)

Do I need to publish the Google OAuth app to production?

For test-user use, no.

Why does my Brand account channel fail to connect?

Brand accounts need extra setup.

Which redirect URI should I use on Railway?

Use your RAILWAY_PUBLIC_DOMAIN with https and the path /integrations/social/youtube appended.

Why does scheduling stall when Temporal is unreachable?

Scheduled posts run as Temporal workflows, so nothing fires without the engine.

Should I set NOT_SECURED or DISABLE_REGISTRATION?

Set NOT_SECURED=true only while you log in over the default up.railway.app domain.

How does this compare to YouTube Studio's native scheduler?

YouTube Studio schedules uploads for your channel at no extra cost but only covers YouTube.
