## Polylane reads every service, log and metric.

### Knows when a service crashes

Railway tells Polylane the moment a deployment fails or crashes, and the investigation starts right away.

### Tracks CPU, memory and disk

Each service is checked against its own normal. No thresholds to tune.

### Reads deploy and runtime logs

Polylane pulls the logs while it investigates, so the answer comes with the lines that prove it.

### 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.

### Reads variable names, never values

Variable names are enough to link services across clouds. Polylane never reads the values.

### Read scopes only

Code fixes go to the repo behind the service. Any write against Railway waits for your approval unless you've allowed it ahead of time.

## 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 with your approval.

**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, and any write, including a restart or redeploy, pauses for your approval unless you've allowed it ahead of time.

**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?**

There's a free plan to get started. Every plan, price and limit is on polylane.com/pricing.

Get started with one command: `curl -fsSL https://polylane.com/setup | bash` installs the CLI, connects your coding agents, and creates the account.
