Railway is a modern PaaS that offers "Infrastructure from Code". It introspects your repo and deploys it. Can also deploy Databases (Postgres, Redis, Mongo).
Railway是一款现代化的PaaS平台，提供“基础设施即代码（Infrastructure from Code）”能力。它会自动分析你的代码仓库并完成部署，也支持部署数据库（Postgres、Redis、Mongo）。
When to Use
适用场景
Heroku Alternative: Cheaper and more modern interface than Heroku.
Databases: Spining up a private network with a Service and a Redis/Postgres DB is 1 click.
Monorepos: Excellent support for building multiple services (frontend, backend, worker) from one repo.
Heroku替代方案：相比Heroku更经济实惠，且界面更现代化。
数据库部署：一键即可创建包含服务与Redis/Postgres数据库的专用网络。
单仓项目（Monorepos）：出色支持从单个代码仓库构建多个服务（前端、后端、任务处理进程）。
Quick Start (CLI)

Best Practices (2025)
2025年最佳实践
Do:
Use Private Networking: Services communicate over private IP (IPv6). Explicitly expose only what needs public access.
Use Templates: One-click deploy "PostHog", "Metabase", "Cronicle".
Use Priority Boarding: For critical production apps, upgrade the plan to ensure capacity.
Don't:
Don't rely on ephemeral disk: Just like Heroku, filesystem is reset on deploy.
