 Deploy your application to Cloudflare Workers using their one-click deployment process, and you're ready to go!
 
+### Railway
+
+Railway automatically detects Build and Start commands when building and deploying to a service.
+
+Set the `target` value to `node-server` in your `vite.config.ts` file.
+
+```ts
+// vite.config.ts
+import { tanstackStart } from '@tanstack/react-start/plugin/vite'
+import { defineConfig } from 'vite'
+
+export default defineConfig({
+  plugins: [tanstackStart({ target: 'node-server' })],
+})
+```
+
+Ensure `build` and `start` npm scripts are present in your `package.json` file:
+
+```json
+    "build": "vite build",
+    "start": "node .output/server/index.mjs"
+```
+
+Then you can run the following command to build your application:
+
+```sh
+npm run build
+```
+
+You can start your application by running:
+
+```sh
+npm run start
+```
+
 ### Node.js
 
 Set the `target` value to `node-server` in your `vite.config.ts` file.
