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 Ruby file from scratch?

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

Online Ruby Editor

Edit Ruby scripts with block folding and highlighting. OpenEdit runs the same editor engine as VS Code directly in your browser tab — open a .rb file or start from a blank one, and nothing is ever uploaded.
