Deploy and Host n8n v3 Release Candidate on Railway

Deploy n8n v3 Release Candidate on Railway with PostgreSQL, persistent storage, and daily backups for both. Using the n8nio/n8n:v3-rc image, this template lets you explore the upcoming major release, test workflows, and evaluate compatibility while keeping your database and application data backed up.

About Hosting n8n v3 Release Candidate

n8n is a workflow automation platform that connects applications, APIs, and services through visual workflows. This Railway template deploys the v3 release candidate alongside PostgreSQL, with persistent storage for n8n configuration and binary data. Railway's public domain is used to configure webhook URLs, and the HTTP proxy exposes n8n on port 5678. Execution-data pruning is enabled to limit retained execution records, while filesystem-based binary data storage keeps binary data on the persistent volume. Daily backups are configured for both PostgreSQL and the n8n volume, helping protect workflow records, configuration, and stored data. As a release candidate, this template is best suited to testing, development, and compatibility checks rather than critical production workloads.

Common Use Cases

n8n visual workflow editor

Test n8n v3 features and compatibility ahead of a stable release.
Build and evaluate automated workflows connecting APIs and applications.
Experiment with webhooks, scheduled jobs, and data-processing workflows.
Test existing n8n workflows against the upcoming major version.

Dependencies for n8n V3 Release Candidate

n8n — workflow automation platform distributed under its Sustainable Use License.
PostgreSQL — database for workflows, credentials, and execution records.
Railway — hosting platform for the application, database, and persistent storage.

Important Notes

Release candidate: Uses n8nio/n8n:v3-rc. This is a pre-release build intended for testing; its contents may change as development progresses.
Persistent storage: The n8n volume is mounted at /home/node/.n8n.
Daily backups: Both the PostgreSQL database and n8n volume have daily backups configured.
Access: Generate a Railway public domain to access the n8n editor and receive webhooks.
Execution retention: Execution-data pruning is enabled, with a maximum count of 200 executions configured.
Encryption key: Keep the configured encryption key stable and protected. Losing it can prevent n8n from decrypting stored credentials.

Why Deploy n8n v3 Release Candidate on Railway?

Railway is a singular platform to deploy your infrastructure stack, including applications, databases, and persistent storage, without managing servers yourself. This template brings n8n v3 RC and PostgreSQL together in a deployable setup, with persistent storage and daily backups for both the database and n8n volume. You can focus on evaluating workflows and testing the next major version while Railway manages the underlying infrastructure.
