Polylane.

Polylane connects a team's code, cloud infrastructure and observability data into one context graph. Its agents investigate incidents, open pull requests with proposed fixes, and review code changes against live telemetry so risky merges are caught before they reach production. Engineers can also ask about production in Slack or through MCP and CLI tooling.

On-call still depends on people piecing together alerts, logs and code after something breaks, while coding agents ship changes without that production context.
