Common questions

Do I need an account to use Codepad?

No. Click "+ new pad" and you get a shareable URL instantly. Your collaborator opens the same link, no signup either.

Is Codepad free?

Yes. Codepad is free to use, with no plan upgrades and no seat counts.

How is Codepad different from Google Docs?

Codepad gives you the same "send the link" ergonomics as Google Docs, but with a real code editor underneath: syntax highlighting for 40+ languages, line numbers, bracket matching, multiple files per pad, and a private notes panel.

Can I share code without signing up?

Yes. Type into the editor on the homepage and hit share. Codepad creates the pad and gives you a URL you can send to anyone. Neither of you needs an account, and whoever opens the link can edit alongside you straight away.

Can I run code in Codepad?

Codepad is for writing, discussing, and sharing code. It does not include a compiler, terminal, or test runner. Use your local environment to execute a solution.

Does a read-only link lock my pad?

No. It creates a separate link for viewing the saved code. People with the edit link can still make changes, and those changes may appear when the read-only page is opened or refreshed.
