Everything Polylane reads from your Railway workspace.
Project Environment Service Deployment Volume Domain TCP Proxy Notification Rule Polylane reads every service, log and metric.
Deployment - crashed
- investigation starts right away
Knows when a service crashes
Railway tells Polylane the moment a deployment fails or crashes, and the investigation starts right away.
- CPU vs its normal
- memory vs its normal
- disk vs its normal
Tracks CPU, memory and disk
Each service is checked against its own normal. No thresholds to tune.
Evidence - deploy logs
- runtime logs
- proof the lines that show it
Reads deploy and runtime logs
Polylane pulls the logs while it investigates, so the answer comes with the lines that prove it.
Project - Service
- Volume
- Domain
- database next to its services
Databases next to their services
Projects, environments, services, volumes and domains sit in one graph, with each database next to the services that use it.
- variable name read
- variable value never read
Reads variable names, never values
Variable names are enough to link services across clouds. Polylane never reads the values.
OAuth - read scopes
- code fixes repo behind the service
Read scopes only
Code fixes go to the repo behind the service.
Use Railway with any coding agent. Polylane connects them.
Connect your agent to Polylane once and it can query Railway alongside the rest of your stack.

Common questions.
Is Polylane an AI SRE for Railway?
It does that work; we call it self-operating software. Polylane keeps your projects, services, deployments and volumes in one graph, investigates what breaks and fixes it.
How does Polylane know a deploy failed?
Railway webhooks flag failed and crashed deployments the moment they happen and clear on the next good deploy. You can also have Polylane review every deploy.
Does Polylane read my environment variables?
It reads variable names, so a service pointing at a database in another cloud shows up connected in the graph. It never reads the values.
Can Polylane change my Railway services?
Polylane investigates and explains. Code fixes are opened on the repo behind the service.
Does it work with my observability provider?
Yes. Polylane supports all the major observability providers, and you can connect any other through MCP. The full list is on polylane.com/integrations.
What does it cost?
Every plan, price and limit is on polylane.com/pricing.
