Railway spending cap: Yes
Does Railway have a hard spending cap?
Yes Per the docs as of Oct 14, 2026: Usage Limits let you set a custom email alert and a hard limit, separately for Compute and Agent usage.
How do I turn on a spending limit in Railway?
- Workspace Usage page > Set Usage Limits (workspace admin required).
- Set a Custom email alert and a Hard limit for Compute Usage (and Agent Usage).
- CLI alternative: railway usage limit set --target workspace --soft 75 --hard 125
What happens when the Railway limit is hit?
Hitting the Compute hard limit takes all your workloads offline; hitting the Agent hard limit disables the agent but leaves workloads running.
Gotchas
- Hard limit = your services go down.
- Personal account vs workspace limits are separate; use the account switcher.
