# Astro on Railway

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

Railway publishes its own guide for deploying Astro.

Content-focused framework that ships zero JavaScript by default and renders components from several UI libraries.

## What Astro needs

Every host claims to run Astro, so the claim on its own decides nothing. These are the things Astro requires from the platform underneath it, and what Railway publishes about each. Railway documents 2 of the 4.

| Requirement | Railway | Why it matters |
| --- | --- | --- |
| Build allowance | Not documented | Astro prerenders by default, so most of the work happens at build time and the build allowance is the real constraint. |
| Concurrent builds | Not documented | A content site rebuilds on every edit. One build slot turns a busy publishing day into a queue. |
| Edge network | Supported | A prerendered Astro site is a directory of static files. After that, the only thing left that affects speed is where they are served from. |
| Git deployment | Supported | Astro's usual workflow is a push that triggers a build. Anything else means wiring the build yourself. |

## What it costs to run there

|  | Railway |
| --- | --- |
| Entry paid plan | $5 / month (Hobby) |

| 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.
