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 JSX / TSX file from scratch?

Yes. Use the “Start a blank JSX / TSX file” button and you get an empty .tsx buffer with JSX / TSX highlighting already enabled.

Online JSX / TSX Editor

Edit React components in JSX or TSX with full syntax support. OpenEdit runs the same editor engine as VS Code directly in your browser tab — open a .tsx file or start from a blank one, and nothing is ever uploaded.
