Deploy and Host self hosted Postiz Bluesky (Social Media Scheduler for Bluesky) on Railway

This template deploys a self-hosted Postiz set up for scheduling Bluesky posts and threads. It suits people and small brands who want a Bluesky scheduler they control.

About Hosting Postiz Bluesky open-source software on Railway (self hosted Postiz for Bluesky scheduling template)

Your posts, drafts, and scheduled queue live in your own Postgres database, not on a vendor's servers.

Railway handles provisioning the four services, wiring the private link to Temporal on port 7233, attaching the uploads volume, and giving you a public HTTPS domain.

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

Buffer bills per channel, so the cost climbs as your Bluesky presence grows. Railway's $5 trial credit is enough to test the stack before you commit.

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 Bluesky 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 Bluesky self hosting

Here's how Railway compares with running your Postiz Bluesky scheduler on a VPS.

Provider	What You Get with Railway	What You Get with the Other Provider
DigitalOcean	Postiz, Temporal, Postgres and Redis from one template, with no server to patch.	A droplet you size and secure yourself, with Docker and the compose stack on you.
AWS	A managed deploy with Postiz already linked to Temporal on port 7233.	Full control of VPC and IAM, but every service and the Bluesky setup is manual.
Hetzner	Hosting for the whole stack without touching a server, fine for a light posting schedule.	Low-cost servers with plenty of RAM, but you handle the OS, HTTPS and backups.

Either route works, so pick the one that matches how much server work you want to do.

Common Use Cases for hosted Postiz Bluesky

Scheduling Bluesky posts and threads: Queue a week of posts on Sunday night and let Postiz publish them on time. Threads go out as chained replies, so you write the whole thread once.
Cross-posting to other channels: Write once and send the same post to Bluesky and your other connected networks. Tweak the wording per platform before it goes live.
Posting through the public API: Scripts and your own site can create scheduled posts for your Bluesky channel without opening the dashboard. Your API key stays on your server.
Team review before publishing: Drafts can pass through a teammate before they reach a brand's Bluesky feed.
Keeping drafts on your server: Drafts, scheduled posts, and uploaded images stay in your own Postgres database and the /uploads volume, under your backup rules.

Dependencies for Postiz Bluesky Docker hosted on Railway

This template runs as four services that depend on each other in a fixed order. Redis 8.2 handles queues and caching.

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

Deploy in this order: Postgres 18, Redis 8.2, Temporal 1.28.1, then postiz. Postiz will crash-loop if it starts before its database or Temporal is reachable.

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

The postiz service runs the official Postiz image, so you build nothing yourself. Set DISABLE_REGISTRATION to true once your first account exists.

How does Postiz Bluesky compare against other ways to schedule Bluesky posts

Postiz Bluesky vs Buffer (Buffer Alternative)

Where Postiz wins: You host it yourself, so drafts, calendar, and post history stay on your own server.
Bluesky setup: No developer app is needed for Bluesky. You add the channel from the UI, and no environment variables are required for it.
Where Buffer wins: It's hosted, so there's nothing to run and no Postgres, Redis, or Temporal to maintain.
Cost shape: Buffer bills per channel, while self hosting on Railway is one infrastructure bill that doesn't grow with each account.

Postiz Bluesky vs Typefully (Typefully Alternative)

Where Postiz wins: It covers many networks from one calendar, so Bluesky sits beside your other channels.
Thread writing: A thread is just multiple entries in the post's value array, each chained as a reply to the last.
Where Typefully wins: It's built around drafting and polishing threads, so the writing experience is more focused.
Ownership: Your content lives on your own deployment rather than a third party's.

Postiz Bluesky vs Hootsuite (Hootsuite Alternative)

Where Postiz wins: It's open source under AGPL-3.0 and free to self host, with no per-user enterprise seat fees.
Where Hootsuite wins: It has mature enterprise features, deep team permissions, and vendor support a large organization may need.
Bluesky scope: Postiz is leaner, so expect fewer advanced reporting and approval features.
Operations: You own uptime and upgrades of a self hosted Postiz, which is more work than letting Hootsuite run it.

Postiz Bluesky vs Skyfeed (Skyfeed Alternative)

Where Postiz wins: It's a general scheduler for many networks, so one tool handles Bluesky and your other accounts.
Where Skyfeed wins: It's aimed at feed and Bluesky-focused workflows, so if Bluesky is your only network it may fit more naturally.
Scheduling: Each post gets an ISO date, so you control exactly when it goes out.
Control: A self hosted Postiz keeps your posting history and API access on infrastructure you choose.

How to use Postiz Bluesky (the OSS social media scheduler)?

Here is the first-day routine once the deploy is green.

Create a Bluesky app password in Bluesky settings under App Passwords. Copy it now, because Bluesky won't show it again.
Open your Postiz domain, sign up for the admin account, and go to the channels area.
Add a channel, choose Bluesky, and enter your handle and the app password.
Write a post and attach an image if you want one.
Schedule it for later, or post now to test the connection.
Check the calendar to confirm the post is queued.

To confirm scheduling works from outside the UI, call the public API:

curl -X POST https://your-domain/api/public/v1/posts \
  -H "Authorization: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"type":"schedule","date":"2026-11-02T10:00:00.000Z","posts":[{"integration":{"id":"YOUR_BLUESKY_CHANNEL_ID"},"value":[{"content":"Test post from the API","image":[]}],"settings":{"__type":"bluesky"}}]}'

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

Clone the Repository

On a Linux VPS with Docker and Docker Compose installed, pull the official repository and move into it.

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

Install Dependencies

You don't install Node or Postgres by hand. Plan on roughly 2 GB of RAM and a domain with HTTPS for OAuth callbacks.

Configure Environment Variables

Copy the example env file and set your public URLs. Bluesky needs no extra keys, since you add the account from the Postiz UI.

cp .env.example .env
# replace your-domain with your real domain
# MAIN_URL=https://your-domain
# FRONTEND_URL=https://your-domain
# NEXT_PUBLIC_BACKEND_URL=https://your-domain/api

Set a long random JWT_SECRET, and set DISABLE_REGISTRATION to true once your admin account exists.

Start the Postiz Bluesky Application

Bring the stack up in the background, then open your domain to finish signup and add your Bluesky channel.

docker compose up -d
docker compose logs -f postiz

Railway handles the Postgres, Redis, Temporal and networking wiring for you, which is the main thing you give up when you run this yourself.

Official Pricing of Postiz Bluesky (Postiz pricing)

Postiz is open source under AGPL-3.0, so the self hosted software is free to download and run. If you self host, your real costs are the server and storage for uploads.

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

Hosted schedulers bill you monthly and keep the server out of your hands. Here's how that trade looks in practice.

Monthly cost of self hosting Postiz Bluesky on Railway

System Requirements for Hosting Postiz Bluesky on a VPS

On a plain VPS, plan for about 2 GB of RAM or more, since the stack runs the app, Temporal, Postgres and Redis together. You'll need a domain with HTTPS.

Frequently Asked Questions (FAQs)

Should I use my main Bluesky password in Postiz?

No. If something goes wrong, you can revoke just that app password without touching your main login.

Do I need to create a developer app for Bluesky?

No. You add the account from the Postiz UI and you're set.

Can Postiz schedule Bluesky threads?

Yes. Number them in the copy, like "1/" and "2/", so readers can follow along.

Can I attach images to a Bluesky post?

Yes. If a post with images fails, check the backend service logs first.

What are the Bluesky character limits in Postiz?

Postiz does not document a specific Bluesky character limit, so I can't confirm the exact number here.

How do I revoke Postiz's access to my Bluesky account?

Go to bsky.app/settings/app-passwords and delete the app password you created for Postiz. That cuts off access immediately, and you can then remove the channel from the Postiz UI.
