# SvelteKit on Railway

Canonical: https://inetgeek.com/stacks/sveltekit-on-railway/

Railway publishes its own guide for deploying SvelteKit.

Svelte application framework that targets different deployment platforms through adapters.

## What SvelteKit needs

Every host claims to run SvelteKit, so the claim on its own decides nothing. These are the things SvelteKit requires from the platform underneath it, and what Railway publishes about each. Railway documents 3 of the 4.

| Requirement | Railway | Why it matters |
| --- | --- | --- |
| Max request duration | 15 minutes while data keeps transferring; closed after 5 minutes with no data transferred. Websocket connections are exempt and can stay open indefinitely. | SvelteKit load functions and form actions run on the server per request, bounded by this ceiling. |
| Edge network | Supported | The adapter decides where handlers run. An edge network is what makes the edge adapters worth choosing. |
| Build allowance | Not documented | Prerenderable routes are resolved at build time, so build allowance scales with the size of the site. |
| Scales to zero | Limited — Serverless sleeps an idle service, but a slept service still holds a slot and is de-prioritised. | Adapter output is usually a function per route. Scaling to zero removes idle cost at the price of a cold start. |

### SvelteKit features on Railway

- **node_adapter**: Supported — Your app has been configured to use the SvelteKit Node adapter. [...] Svelte builds your project into a build directory. The server starts when the server entry point is executed, which is by default located at build/index.js ([source](https://docs.railway.com/guides/sveltekit))
- **dockerfile_deploy**: Supported — This guide covers how to deploy a SvelteKit app to Railway in four ways: One-click deploy from a template. From a GitHub repository. Using the CLI. Using a Dockerfile. [...] Railway automatically detects the Dockerfile, and uses it to build and deploy the app. ([source](https://docs.railway.com/guides/sveltekit))
- **isr**: Not supported — Frameworks that support ISR Next.js ( revalidate option in App Router or getStaticProps ) Nuxt ( routeRules with swr or isr options) [...] SvelteKit Yes Yes No Yes ([source](https://docs.railway.com/guides/ssr-ssg-isr))

## What it costs to run there

|  | Railway |
| --- | --- |
| Entry paid plan | $5 / month (Hobby) |
| Pricing model | A base subscription fee that goes towards usage, with the plan's own credit included; anything beyond the credit is billed as resource usage. |
| When you exceed a cap | Billed automatically: on the Hobby plan ($5/month, includes $5 of resource usage) usage above the included amount is charged as a delta on top of the subscription — no throttling or suspension is documented |
| Regions | 4 regions: California, Virginia, Amsterdam, Singapore |

## Whether it suits you

Teams that want a plan fee which doubles as usage credit, and deploy services straight from a Dockerfile without managing servers. The $5 Hobby fee comes back as $5 of resource usage.

Consider something else if: You need to run in a region outside California, Virginia, Amsterdam or Singapore.
