Telemetry

@c15t/cli collects anonymous usage data to help us prioritise features and find rough edges in workflows. It is fully optional — the CLI works the same with telemetry disabled.

What we collect

• Which command was run (e.g. setup, codemods, self-host migrate).
• Whether the run succeeded or failed.
• Which framework was detected (React, Next.js, vanilla).
• The CLI version and Node.js version.
• A randomly generated, anonymous machine ID (rotates if you reset config).

What we do not collect

• Source code, file contents, or file paths.
• Environment variables or secrets.
• Configuration values from your c15t.config.
• Personally identifiable information.

How to disable

Per-run:

pnpm dlx @c15t/cli setup --no-telemetry

Permanently for your user:

export C15T_TELEMETRY_DISABLED=1

Add the export to your shell profile (.zshrc, .bashrc, etc.) to make it persistent.

Source

The telemetry implementation is open source — see packages/cli/src/utils/telemetry.ts for the exact event names and payloads.
