In short
Railway bills what your app actually uses, so a small or mostly idle app is cheap, and bandwidth costs $0.05 per GB from the first gigabyte. Render sells fixed instances, which keeps the bill predictable, but its Hobby workspace includes only 5 GB of bandwidth and charges $0.15 per GB after that, so traffic-heavy apps pay more there. Render has a free tier that sleeps; Railway has a small free plan and services that sleep when idle.
Railway
- Usage-based: $20 per vCPU-month and $10 per GB-month of memory actually used, billed per second.
- Hobby costs $5 a month and includes $5 of usage; Pro costs $20 and includes $20.
- A free plan gives $1 of usage a month, capped at 1 vCPU and 0.5 GB of memory per service.
- Idle services can sleep and cost nothing while asleep; the next request wakes them.
- Egress $0.05 per GB from the first gigabyte; volumes $0.15 per GB-month, up to 5 GB on Hobby.
- Postgres runs as an ordinary service at the same rates. Replicas can't use volumes.
Render
- Fixed monthly instances from $7 (0.5 CPU, 512 MB) to $175 (4 CPU, 8 GB), billed by the second.
- Free instances sleep after 15 minutes idle; a workspace gets 750 free instance hours a month.
- Hobby workspace (one seat): 5 GB of bandwidth, then $0.15 per GB. Pro: $25 a month with 25 GB.
- Postgres from $6 (256 MB) or $19 (1 GB) plus $0.30 per GB of storage; free Postgres expires after 30 days.
- Disks $0.25 per GB-month; a service with a disk can't scale to several instances.
