[Deploy a Remote MCP Server Over HTTPS](https://railway.com/guides/deploy-remote-mcp-server.md): Deploy an existing MCP server, such as Playwright MCP, to a public HTTPS endpoint on Railway with object storage and bearer-token auth, and compare Railway against Render, Fly.io, Cloudflare, and AWS as a host. 2. [Configure Client-Side Routing for Single-Page Applications](https://railway.com/guides/spa-routing-configuration.md): Set up Caddy or Nginx to handle client-side routing for single-page applications on Railway. Avoid blank pages on refresh and configure fallback routes. 3. [Deploy a WebSocket Application with Socket.IO](https://railway.com/guides/socketio.md): Deploy a Socket.IO server and client on Railway. Covers CORS configuration, reconnection handling, and scaling with a Redis adapter. ## Build and deploy - [Deploy Caddy](https://railway.com/guides/caddy.md): Learn how to deploy Caddy on Railway with one-click templates or CLI. This guide covers how to choose plugins, and configure static sites and reverse proxies. - [Deploy Static Sites with Zero Configuration and Custom Domains](https://railway.com/guides/static-hosting.md): Learn how to deploy static websites to Railway with automatic GitHub builds, SSL certificates, custom domains, and integrate with a CDN. Perfect for marketing sites, blogs, and documentation. - [Add a CDN using Amazon CloudFront](https://railway.com/guides/add-a-cdn-using-cloudfront.md): Learn how to integrate Amazon CloudFront as a CDN for your Fastify app in this step-by-step guide. ## Run in production - [Set up a Tailscale Forwarder](https://railway.com/guides/set-up-a-tailscale-forwarder.md): Learn how to access services on your private network on Railway by using a Tailscale Forwarder. - [Receive Webhooks at Scale](https://railway.com/guides/webhooks-at-scale.md): Build a webhook receiver that verifies signatures, responds fast, and queues work for a background worker. Covers idempotency keys, retries, and how to run the pattern on Railway. - [Create a Bridge from Railway to AWS RDS with Tailscale](https://railway.com/guides/bridge-railway-to-rds-with-tailscale.md): Learn how to securely access your AWS RDS database from Railway using a Tailscale subnet router. ## Compare and decide - [The Best PaaS for Multi-Region Deployments in 2026](https://railway.com/guides/best-paas-multi-region-deployments-2026.md): Narrower than the general multi-region listicle. Specifically the PaaS-shaped products that handle deploys, scaling, routing, and database adjacency across regions, with the seven regions Railway runs in as the anchor. - [The Best Multi-Region Hosting Platforms in 2026](https://railway.com/guides/best-multi-region-hosting-platforms-2026.md): Multi-region means three different things in 2026, and most listicles conflate them. A ranking that separates static asset CDN, stateless compute multi-region, and true multi-master writes. - [Choose Between SSE and WebSockets](https://railway.com/guides/sse-vs-websockets.md): When to use Server-Sent Events vs WebSockets for real-time data. Covers protocol differences, reconnection handling, and how to deploy both on Railway. - [Railway vs Cloudflare: How Their Architectures Differ and When to Use Each](https://railway.com/guides/railway-vs-cloudflare-how-their-architectures-differ-and-when-to-use-each.md): A detailed technical breakdown of Railway and Cloudflare’s developer platform. This guide explains how their compute, storage, and networking models differ, where each platform excels, and why they fit fundamentally different use cases. It covers tradeoffs, and architecture patterns for teams choosing between Containers and Workers, or combining both platforms for production workloads. ## More guides - [Serve a Multi-Region API with Failover](https://railway.com/guides/multi-region-api-failover.md): Run one API service across multiple Railway regions with replicas, nearest-region routing, and automatic replica restarts. Covers routing behavior, health checks, and what failover Railway gives you. - [Speed Up a Global App with Cache-Control Headers and a CDN](https://railway.com/guides/cache-headers-cdn.md): Set Cache-Control headers correctly for static assets, HTML, and API responses, then put a CDN in front of your Railway service to serve users from the nearest edge. ## Related topics - [Frontend](https://railway.com/guides/topics/frontend.md): Ship Next.js, Astro, SvelteKit and SPAs, and run Node.js, Bun and full-stack TypeScript apps. - [Comparisons and Migrations](https://railway.com/guides/topics/comparisons.md): How Railway compares with other platforms, what it costs, and how to move over from Heroku, AWS and others. - [Backend](https://railway.com/guides/topics/backend.md): APIs, background workers, queues, cron jobs and webhooks. - [Storage](https://railway.com/guides/topics/storage.md): Run Postgres, Redis, MySQL and object storage on Railway: pooling, backups, migrations and vector search. - [AI Agents](https://railway.com/guides/topics/ai.md): Host agents, MCP servers, RAG pipelines, model gateways and inference services.
