Aria vs Railway. Flat, not metered.
Railway made deploying services and databases pleasant, and bills for what they use. Aria gives you one server that is yours alone, puts every service and database on it, and charges one flat price however busy they get.
In one line: Railway suits small, bursty projects billed by usage. Aria suits a product with several always-on services and databases that you want at a predictable monthly price.

What Railway does best
Railway has one of the nicest developer experiences around: a visual canvas of services, instant databases and templates. For prototypes and small apps that idle most of the day, usage billing can be very cheap.
Choose Aria when
- Your services and workers run all day, so usage billing adds up.
- You want the month’s bill known in advance, not after.
- You want your app and its databases on one machine, with local connections.
- You want your coding agent to deploy with server-enforced approval gates.
Stay on Railway when
- The project is small and idle most of the time, so usage stays low.
- You rely on Railway’s templates or its multi-region features.
Moving from Railway to Aria
- Ask your coding agent to write aria.yaml listing your services and databases (it reads your Railway setup from the repository).
- Aria recommends the smallest server that fits the whole stack.
- Move your Postgres with a dump and restore; add your variables once.
- Launch, then point your domain.
Questions
Is Aria a Railway alternative?
Yes, for products with several always-on services and databases. Aria puts them on one dedicated server at one flat monthly price instead of billing each by usage.
Will my bill change with traffic on Aria?
No. The price is per server per month. If you outgrow it, you move up a size, and you choose when.
Can I run background workers on Aria?
Yes. Workers are long-running services on your server: they never sleep and are included in the price.
What if my stack doesn’t fit one server?
Aria estimates memory from aria.yaml before you pay, and recommends a bigger size or tells you when it won’t fit.
How much does Aria cost compared with Railway?
Aria charges one flat monthly price per server, from £9 a month ex VAT (draft prices), in GBP, with no charges per seat, per app, per database or per request. Railway’s pricing is on its own pricing page (https://railway.com/pricing); its model is summarised in the table above, checked 22 October 2026.

How the price works
No charges per seat, app, database or request
- No charge per seat
- No charge per app
- No charge per database
- No charge per request
One server. One price.
An Aria plan is one monthly price for one server. Run as many apps, workers and databases on it as it can hold, and invite your agents too: nothing is metered per seat, per app or per request.

Let your coding agent write aria.yaml and see which server fits your stack.
