These settings apply to all code editor panels across every tool.

All tools run entirely in your browser. No data leaves your device — there are no accounts, no analytics, and no telemetry. Tool inputs are saved in localStorage so you can switch tools without losing your work.

elvion devtools is a growing collection of local-first developer tools. All processing happens in your browser — no accounts, no telemetry, no data sent anywhere.
