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 actually requires from the platform underneath it, and what Railway publishes about each. Railway documents 3 of the 4.
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.

- Specs & Limits — Railway Docs ↗
“HTTP requests can run for up to 15 minutes if data keeps transferring (for example, keep-alive heartbeats), and are otherwise closed after 5 minutes with no data transferred. [...] Websocket connections are exempt from these duration and inactivity limits, and can stay open indefinitely, even while idle.”

Edge network
Supported
The adapter decides where handlers run. An edge network is what makes the edge adapters worth choosing.

- Edge Networking — Railway Docs ↗
“Railway uses a globally distributed edge network to route traffic to your deployments. [...] Edge POPs are the entry points where user traffic first reaches Railway. Each request is terminated at the nearest POP and tagged with that POP's ID in the X-Railway-Edge header.”

Build minutes
Not documented
Prerenderable routes are resolved at build time, so build allowance scales with the size of the site.
Scales to zero
Limited
Adapter output is usually a function per route. Scaling to zero removes idle cost at the price of a cold start.

- Serverless (App Sleeping) | Railway Docs ↗
“Serverless allows you to increase the efficiency of resource utilization on Railway and may reduce the usage cost of a service, by ensuring it is running only when necessary. [...] When Serverless is enabled for a service, Railway automatically detects inactivity based on outbound traffic. [...] Inactivity is sampled on an interval rather than measured continuously, so in practice a service sleeps somewhere between 5 and 10 minutes after its last outbound traffic. [...] Slept services still consume a slot on Railway's infrastructure.”

What it costs to run there.
- Entry paid plan
- $5 / month (Hobby)
- Pricing model
- Plan fee that includes an equivalent usage credit
- 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.
