Monthly cost for three real workloads

The rate cards applied to identical usage. This is where the winner changes.

Workload	Fly.io	Railway	Cheaper
Side projectA personal site or small app with modest traffic, a few gigabytes of assets, and one small always-on process.	$5.19	$10	Fly.iosaves $4.81/mo (48%)
Growing SaaSA funded product serving a few thousand daily users, with an image-heavy frontend and two application servers.	$23	$55	Fly.iosaves $32/mo (58%)
Media-heavy siteA publisher or video product where delivery dominates the bill and compute is almost an afterthought.	$203	$505	Fly.iosaves $302/mo (60%)

Workload definitions are identical on every comparison page, so figures here can be read against any other pair in the same category.

What each one is for

Fly.io

by Fly.io

Containers run as Firecracker VMs across dozens of regions, billed per second, with the cheapest egress of any application platform by a wide margin.

Railway

by Railway

Bills per second of actual CPU and memory consumption rather than per provisioned instance, which makes irregular and low-traffic workloads markedly cheaper than flat-rate platforms.

Free tier: $5 of usage included on the Hobby plan
