Railway vs Vault
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; Vault vault 1.15.0 and later is licensed under the Business Source License 1.1, not an OSI open source licence, with IBM Corporation as licensor
- They diverge on capability: Railway covers Git integration, Vault covers Secrets management.

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
Vault
- Vault 1.15.0 and later is licensed under the Business Source License 1.1, not an OSI open source licence, with IBM Corporation as licensor
- The Additional Use Grant forbids offering Vault to third parties on a hosted or embedded basis in a paid product that competes with IBM's paid versions of Vault
- Each version only converts to MPL 2.0 four years after that version is published, and the Change Date is tracked per version
- Replication, HSM support, namespaces, performance standby nodes, FIPS builds, control group authorisation, multi-factor authentication, secrets sync and lease count quotas all require a Vault Enterprise licence
- A Vault Enterprise licence must be applied to the cluster before any Enterprise feature can be used
