Deploy and Host Flagsmith on Railway

Flagsmith is an open-source feature flag and remote configuration platform that helps teams control feature rollouts, manage environment-specific configurations, and experiment safely without redeploying code. It supports multi-environment setups, user segmentation, and real-time flag updates across web, mobile, and backend applications.

About Hosting Flagsmith

Hosting Flagsmith involves deploying its API, UI, and background task processor along with a PostgreSQL database for storing feature flags, environments, users, and analytics data. In production setups, Flagsmith typically runs as containerized services and relies on environment variables for configuration such as database connections, allowed hosts, and domain settings. Railway simplifies this process by handling container orchestration, networking, scaling, and environment management, allowing you to focus on feature management instead of infrastructure maintenance.

Common Use Cases

Feature flag management for staged rollouts and canary releases
Environment-specific configuration management (dev, staging, prod)
A/B testing and experimentation without redeployments

Dependencies for Flagsmith Hosting

PostgreSQL (primary data store for flags, users, and analytics)
Docker (for containerized deployment)

Deployment Dependencies

Flagsmith Docker deployment: https://docs.flagsmith.com/deployment/docker

Implementation Details

Example DATABASE_URL format used by Flagsmith:

postgresql://USER:PASSWORD@HOST:5432/flagsmith

Railway automatically injects this value when using its managed PostgreSQL service.
