Railway vs Stackap

Railway bills what your services use on infrastructure it runs; Stackap runs on one server you rent at a fixed price, and the difference shapes everything from cost to how you scale.

The short answer

The cleanest way to compare them is to ask what happens when your app gets ten times busier. On Railway, you are billed for the extra usage and the platform finds the capacity. On Stackap, the app gets more copies on the same server until the server is full, and past that you need a bigger server or a second one, which is not built.

And the reverse question, what happens when your app is idle? Railway's bill falls toward nothing, while a Stackap server costs the same whether it is busy or not.

The other difference is who does the unglamorous work. On a hosted platform, patching the host, replacing failed hardware and watching capacity are someone else's job. On Stackap they are yours, helped by a monitor that checks CPU, memory, disk, certificates and backups, and alerts you, but cannot replace the hardware.

Side by side

	Railway	Stackap
Capacity	Elastic, billed by use	Fixed at one server; 1 to 8 copies of an app
Idle cost	Falls with usage	The server price, always
Busy cost	Rises with usage	Flat until the server is full
Ceiling	The platform's limits	About 700 requests per second per 4-CPU server on one measured site
Failure domain	Spread by the platform	One server
Backups	Provided by the platform	Daily, encrypted, restore-verified, to your bucket
Who patches the host	Railway	You
Data location	Where the platform places it	Where you rent the server

Choose Railway if

Your traffic is spiky and you do not want to size a server for the peak.
You want someone else to patch the host and absorb hardware failure.
You run many services that talk to each other.

Choose Stackap if

Your traffic is steady and fits on a four-core machine.
You want to know your monthly bill in advance.
You want your own encryption key and backup bucket.

What the money looks like

There is no universal winner. A mostly idle app is cheaper on usage billing. A steadily busy app, or a fleet of small ones, is cheaper on a fixed server.

Take your last three months of usage on Railway, find the busiest week, and check that week against the one measured figure of about 700 requests per second per server. If you are far below that, a fixed server probably costs less.

Early-access scope

Stackap has no elastic capacity and no multi-server scaling.
One server is one failure domain, and a full rebuild from nothing has not been tested.
The 700 requests per second figure is from one test of one site's pages and is not a promise for yours.
Stackap is invite-only early access.

Questions

Which is cheaper?

It depends on how busy your app is, as the section above explains. Check your own numbers, not ours.

Can I move gradually?

Yes, one project at a time. Each app and its database moves on its own.

Can I mix the two?

Yes. Keeping a spiky or multi-service system on Railway and moving steady, simple apps to a fixed server is a reasonable split.
