Perplexity

Claude Code controls Fly.io compute

Run `create_machine` and `delete_machine` through your terminal scripts. Claude Code manages your horizontal scaling during build pipelines without a GUI. This fits into your existing CI/CD workflow. It automates the provisioning of ephemeral compute for testing and production tasks.

Headless diagnostics with Claude Code

Use `exec_machine` to run bash commands on remote nodes. Claude Code pipes the output into your shell, making it easy to parse data or trigger follow-up actions. It is designed for backend engineers who prefer the terminal. You get full visibility into your machine processes without needing a browser.

Automate Fly.io state with Claude Code

Claude Code tracks your persistent hardware with `list_volumes` and `get_machine`. It ensures your volumes are attached before your app logic runs. This prevents runtime errors in your deployment scripts. You can verify your infrastructure status before proceeding to the next step of your build.
