Deploy and Host Outline (Self-Hosted Notion Alternative) on Railway

[Updated Aug '26] Outline is a fast, open-source team knowledge base and wiki — a self-hosted alternative to Notion and Confluence. This template runs the full stack (Outline app, PostgreSQL, and Redis) with local file storage on a persistent volume, every secret auto-generated and every service wired over Railway’s private network, so you get a working workspace in one click.

About Hosting Outline (Self-Hosted Notion Alternative)

Hosting Outline means running three coordinated services: the Outline Node.js app, PostgreSQL for documents and metadata, and Redis for the job queue and realtime collaboration. This template pins every image to a known-good tag (outlinewiki/outline:1.9.2, postgres:16-alpine, redis:7-alpine), generates the 64-character hex SECRET_KEY and UTILS_SECRET, sets PGSSLMODE=disable for Railway’s internal network, and stores uploads on a mounted volume via FILE_STORAGE=local. On first boot Outline runs its database migrations and serves a "Create workspace" screen where you set up the first admin account — no external services required to get started.

Common Use Cases

Internal team wiki, handbook, and documentation hub
Product specs, meeting notes, and runbooks with realtime collaborative editing
A self-hosted, data-owned alternative to Notion or Confluence

Dependencies for Outline (Self-Hosted Notion Alternative) Hosting

PostgreSQL 16 and Redis 7 (both included and pre-wired)
For ongoing sign-in beyond the first admin: an email/SMTP provider (SMTP_HOST, SMTP_USERNAME, SMTP_PASSWORD, SMTP_FROM_EMAIL) or an SSO provider such as Google (GOOGLE_CLIENT_ID / GOOGLE_CLIENT_SECRET) or generic OIDC (OIDC_CLIENT_ID / OIDC_CLIENT_SECRET / OIDC_AUTH_URI / OIDC_TOKEN_URI / OIDC_USERINFO_URI). Add these as service variables when you are ready to invite your team.

Implementation Details

DATABASE_URL and REDIS_URL reference the postgres and redis services over the private network. Redis runs with a generated password via a shell-wrapped start command (sh -c) so the password is applied correctly. Uploaded files live on the volume mounted at /var/lib/outline/data; note that local storage is tied to this single instance and does not scale horizontally — switch FILE_STORAGE to S3 with the AWS_* variables if you need shared, scalable object storage.
