Are my files uploaded to a server?

No. OpenEdit processes everything locally in your browser using Web APIs, so your file never leaves your device.

Is this tool free to use?

Yes. Every OpenEdit tool is free, requires no account and adds no watermark to your exports.

Can I create a new Dart file from scratch?

Yes. Use the “Start a blank Dart file” button and you get an empty .dart buffer with Dart highlighting already enabled.

Online Dart Editor

Edit Dart and Flutter sources with widget-friendly folding. OpenEdit runs the same editor engine as VS Code directly in your browser tab — open a .dart file or start from a blank one, and nothing is ever uploaded.
