Frequently asked questions

Is CodeStudio Playground free?

Yes. CodeStudio Playground is free for everyone and needs no sign-up to use. An account is only needed to export, download or print, because every export is recorded.

Are my files uploaded to a server?

No. CodeStudio Playground works inside your web browser, so the files you open are processed on your own device. If you sign in, the work you save (such as drafts and registers) is also kept in your account so it follows you to other devices.

Does it work on a phone?

Yes. It works in current versions of Chrome, Edge, Safari and Firefox on phones, tablets and computers, with nothing to install.
