- From
- Free
- Free plan
- Yes
The short version
- Each has a real cost: Railway plan fees are usage credits rather than allowances, so the $5 Hobby and $20 Pro fees are spent on compute and anything beyond is billed on top; Vellum pricing varies significantly by computational tier, making budget planning difficult
- They diverge on capability: Railway covers Git integration, Vellum covers Persistent AI identity.
- Prices and features above were last checked on 30 August 2026.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Railway
- Plan fees are usage credits rather than allowances, so the $5 Hobby and $20 Pro fees are spent on compute and anything beyond is billed on top
- The free plan carries $1 of monthly credit and caps a service at 1 vCPU and 0.5 GB
- Compute is metered per second for both memory and CPU, so cost tracks uptime rather than traffic and an idle service still bills
- Egress is $0.05 per GB on top of compute
- The Pro fee is per workspace rather than per user or per project
Vellum
- Pricing varies significantly by computational tier, making budget planning difficult
- Requires explicit permission for sensitive actions, limiting autonomy
- Self-hosting option may intimidate non-technical users
- Learning curve to develop customizations with plugins
