Updated June 15, 2026Railway is a modern cloud hosting platform founded in 2020 that simplifies deploying and managing web applications, APIs, databases, and background services. The platform provides instant deployment from GitHub, built-in databases (PostgreSQL, MySQL, Redis, MongoDB), and service networking with minimal configuration.
Railway uses persistent servers rather than serverless functions, providing consistent performance for applications that need long-running processes, WebSocket connections, and stateful workers — requirements common in AI applications. The platform supports Docker containers, offers GPU-enabled instances for AI inference, and provides usage-based pricing that scales from hobby projects to production workloads.
Railway competes with Heroku, Render, and Fly.io as a developer-friendly PaaS (Platform as a Service), but differentiates through its modern design, faster deployments, and built-in observability. The platform has become popular with AI developers who need to deploy model APIs, agent systems, and data pipelines without the complexity of Kubernetes or traditional cloud providers.
