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 Solidity file from scratch?

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